More - What's Maintenance and What's Not!
PAUL D TOMLINGSON
If its equipment and you do something to keep it running, make it run or make it run better then it’s maintenance. If its equipment and you modify it or move it, that’s not maintenance. If you build, construct or install something, you can’t maintain it until it exists. Wait, there’s more . . .   All equipment is in a constant state of deterioration. That’s why PM is ‘detection oriented.’ The idea is to find the problem and fix it before it blows up!   An overhaul can’t be PM as some think. When an overhaul is required there is so much wrong with the equipment that it must be removed from service. There is nothing left to prevent.   Overhauls and rebuilds are not the same thing. You rebuild the truck engine. And you overhaul the truck.   If your objective is to avoid premature equipment failure and extend equipment life, it’s PM.   If the idea is to use continuous monitoring to asses equipment performance to extend equipment life and avoid the consequences of failure its Reliability Centered Maintenance (RCM). And if you are trying to identify the causes of failure and reduce or eliminate them, you must be able to define reliability. Try this:    Reliability – A measure of the capability of a unit of production equipment, process or circuit to operate at designed capacity within its specified operating envelope while adhering to prescribed maintenance requirements within a designated time period and meet established levels of product output or service duration.     Other stuff  - -     When maintenance has not determined which work requires planning, bad stuff happens. First, planners are overcome with processing work orders for jobs that don’t need planning. Then, by the time the maintenance supervisors are alerted, these small jobs have become emergency repairs. And, when the planner realizes he has been conned into ‘the work order administrator’ he has no time left to plan anything.   The term ‘CMMS’ doesn’t really exist. Few maintenance organizations have a dedicated information system. Most use a work order system which is part of a fully-integrated system also used for inventory control, payroll or purchase order tracking all tied to an accounting. It’s a mystery why other departments think the work order system is the exclusive means of maintenance work control. If you do work - - of any kind - - like road grading in the pit - - use the work order system.      The most successful maintenance managers are those who have figured out that they need help from other departments and have managed to tell them how!   The best mine or plant managers are those who recognize that maintenance needs help from other departments and verifies that they get it.   Operations supervisors are really diplomats. They must ensure that operators don’t bust the equipment while trying to find out what maintenance really does and how to get it.   Maintenance craftsmen are actually ‘frustrated art appreciators’. They know that well-planned work make their jobs easier and allows them to perform higher quality work.   Maintenance foremen have the most difficult jobs in industry. No matter who busted the equipment or who is responsible for the ‘no show’ preceding the sudden failure, it’s their fault!   In the view of most operations folks, ‘downtime’ is only a maintenance term.                   
The Best Training Results
PAUL D TOMLINGSON
The Best Training Results - Industry-specific maintenance management training yields positive results. Public maintenance management seminars are often generic and provide few ideas that have immediate application to the mining industry. Other attendees usually have little understanding of mining and cannot share any useful experiences. Expensive attendance fees often preclude attendance and associated travel costs further limit those who might attend. Some topics like ‘supervision’ may have universal themes but the chief janitor has little in common with the smelter foreman. Off-site courses can pull key personnel away from the operation for the seminar duration plus travel time creating a troublesome gap in essential control of work. The timing of potentially useful courses might be in conflict with shutdown schedules further limiting attendance. While specialized topics like condition-monitoring technologies have potential utilization, the factors of cost and absence may outweigh the value gained. Similarly, specialized reliability topics can be valuable but the absence of a maintenance program platform can preclude their useful implementation. And remote mining operations often cannot even consider off-site training no matter the topic or its potential value. Their response is no training no matter the urgency. The tradition of promotion from within ultimately to maintenance manager has produced dismal results primarily because no training is being provided. No public seminar or course can fill this need. This training must come from within. It must not only be industry–specific, it must be site-specific.   These factors were the incentive for creation of the Mining Maintenance Management Course. It mitigates all of these negative training factors by providing complete on-site maintenance management training available to all - - anytime - - without limits. See attachment.
Festival of Maintenance
PAUL D TOMLINGSON
“In 1533 a noblewoman in Calais presented a visiting grandee with a peculiar gift: her personal toothpick, which, she was eager to point out, she had used for seven years.” The visitor’s reaction was not recorded but this tale launched an unusual conference “dedicated to keeping things in good nick.” Held at the Museum of London, its observations were reported in the October 20th issue of the Economist. “Events about making new things are ten-a-penny but less common are events about keeping things as good as new. Maintenance is often dismissed as mere drudgery but - - repair is often trickier than making them.”  “Maintenance lacks the glamour of innovation and it is mostly noticed by its absence -- the tear in a shirt, the mold on a ceiling, the sputtering of an engine.” “It (wear and tear or ‘consumption of fixed capital’) is also more difficult to measure. Statisticians must estimate the lifespan of (assets) and make assumptions about how they deteriorate. Some are like light bulbs, which work well until they stop altogether while other assets were assumed to wear out in a straight line.”   These observations suggest that maintenance is a difficult to execute, measure or manage activity. But they also raise questions. Why is maintenance improvement a perpetual mining industry goal? Are enough of the right things being done to achieve necessary improvements? Do decision-makers know what to do? Is there acknowledgement that effective maintenance is the single most important guarantee of reliable equipment that can ensure a successful mining operation?

Top 3 Issues That a Top-Notch Mobile Sales Solution Will Address
Command Alkon
Spend More Time in the Field Generating Business Mobile technology that allows real-time information to be collected and shared is changing the face of the construction industry. This technology is being used to track daily activities and critical information, and streamline collaboration between teams in the field and at the office. What's shaking up sales processes in the technology world? Mobile sales solutions. Many sales people love their current manual or isolated quoting processes because they’re easy and have very few constraints. However, the rest of the organization often suffers from the headaches resulting from the lack of visibility or audit trails inherent to these processes, which ultimately negatively impacts your organization’s operational stability and growth plans. If this sounds like your organization, it may be time to investigate automated solutions that are designed specifically for the Heavy Building Materials industry that can empower accurate sales forecasting and minimize quoting inaccuracies. What Can A Mobile Sales Solution Do for My Business? Three problems that a mobile sales solutions address includes: 1) Generating timely and accurate quotes: Roughly 25% of Heavy Building Materials production volume is quoted and shipped within 24 hours. Without real-time information, there is room for unintended errors to easily creep into the process; such as outdated pricing and unauthorized discounts. According to well-regarded research firms, these rebills can cost companies up to 5% of the original transaction value. Progressive Ready-Mix Producers and Bulk Material Suppliers are using mobile sales solutions to more effectively perform quoting, monitoring, and forecasting through an investment that can easily pay for itself by eliminating just a handful of credit and rebill situations. 2) Maintaining realistic pipeline estimates and forecasts: Recent research by the Aberdeen Group shows that only around 55% of companies that do not implement a best-in-class forecasting process achieve their sales quotas, compared to 97% of companies that choose to implement advanced forecasting approaches achieving theirs. With a sales solution in place that provides real-time visibility into both an accurate backlog and an accurate sales forecast, you are empowered to make decisions and adjustments that steer your organization in the right direction on a daily basis (even a hourly basis, if needed) instead of relying on a monthly snapshot of quickly outdated information.  3) Missing opportunities due to lack of visibility in the field: How often does your company miss opportunities simply because a bid date is missed?  Does each sales team member have their own approach to selling, quoting, and closing opportunities?  Is pricing consistency a problem you deal with? With a mobile sales solution designed specifically for the industry in place you can gain the visibility you need to monitor and enforce sales activities and ensure a consistent and professional buying experience to your market. MOBILEsales is Command Alkon’s mobile sales solution for the Heavy Building Materials industry. This tool helps you standardize your sales approach across your team and eliminate issues that arise from inaccuracies and inefficiencies.
Eliminate Paper Processes so You Can Focus on What Really Matters
Command Alkon
What's All the Buzz About Electronic Tickets?Paper tickets - this has been a trending topic across the Heavy Building Materials industry for quite some time. Why? Because paper processes are entirely outdated and inefficient, and in an industry that is on-the-go, they can be a hassle to keep track of. Using paper discourages quick billing and quick driver turn around. With the use of mobile technology, drivers can now deliver electronic tickets as soon as materials are delivered. This means quicker invoicing to suppliers and enhanced partnerships. Let's Break It down for You - How Can MOBILEticket Improve Your Business?·        MOBILEticket provides paperless tickets that can’t be lost, rained on, or thrown away. The ticket is an electronic document that is distributable via email without scanning.·        MOBILEticket’s native integration with MCM’s Apex system provides seamless data routing from dispatch to the drivers.·        The intuitive workflow within MOBILEticket makes it easy to learn for new employees.·        Using tablets in their trucks, MOBILEticket can be set up and implemented quickly.Midwest Concrete Materials Sees the Advantages of Implementing MOBILEticketBeing a Command Alkon customer for years, Midwest Concrete rolled out MOBILEticket to the aggregate side of their business. The implementation and training process was straightforward as MCM was already using a number of Command Alkon products. The results of this tool were almost immediate - radio traffic decreased, driver time in the yard decreased and MCM’s internal staff were able to invoice quicker.Placing Focus on What MattersMCM’s drivers appreciate not having to contact dispatch for questions on their tickets. With the paperless tickets they no longer have to manually fill out paper tickets and they get their next ticket displayed on their tablet as soon as they submit the existing ticket. Having all the ticket information on their tablets reduces the amount of questions they have to ask dispatch and there is no risk of the ticket being lost on the jobsite. The reduction in radio traffic increases driver efficiency and allows dispatch to focus on coordinating schedules and getting orders into the system.A+ Customer Experiences and Strengthened Partnerships·The MCM internal staff has seen increased speed at which they can invoice their tickets. The MOBILEtickets are downloaded directly to their financial software and after importing, the tickets are immediately billed. This has reduced time to invoice and eliminated double data entry.Mike Sanson, IT Manager at Midwest Concrete stated, “Our trucks are more efficient, in that they have their assignments immediately upon completion of the previous order. Our drivers have the order information available at their fingertips. The drivers no longer have to fill out paper tickets, and therefore we do not have to double enter to get them into our billing system, eliminating time and mistakes. Our customers receive an email of their ticket immediately in the office alerting them that the material has been delivered, and not waiting on a worker on the job to deliver the paper ticket. Overall, this has streamlined the whole process, and MOBILEticket is a win-win for both our company and our customers.”Want to start a conversation about MOBILEticket? Click here to contact us!
Interested in BIG Productivity Gains? Wipe Out Non-Productive Driver and Fleet Time
Command Alkon
There’s some good, solid news for the construction industry: Dodge Data & Analytics Index projects that we’ll have “moderate strengthening” through the end of 2018. But in terms of productivity, we appear to be heading in a different direction. Of note, a recent survey of 600 global construction leaders* compiled by PlanGrid and FMI Corporation mentions: ·         Poor communication, rework and bad data management cost the construction industry; $177 billion annually in labor costs in the United States alone. ·         Construction workers lose almost two full working days per week solving avoidable issues and searching for project information. ·         Each construction project team member spends more than 14 hours weekly on average dealing with conflict, rework and other issues. ·         Almost half of all rework is due to poor communication among project stakeholders, and poor project information, while 26% of rework is due to poor communication or miscommunication between team members caused unresponsiveness of team members; the inability of project stakeholders to collaborate effectively; and the lack of a common platform for all team members to communicate and share project data. ·         The most common goals for technology adoption included providing better access to project data, improving project productivity and increasing the accuracy of project information. ·         Workers are not taking full advantage of mobile devices and IT investments. Stamp Out Non-Productive Driver and Fleet Time for Big Productivity Gains It stands to reason that companies who address productivity issues will not only avoid scrambling for information and wasted hours and energy but also quickly gain competitive advantage. If you’re managing drivers and trucks that wheel in and out of numerous sites during the day or week and aren’t using automatic processes via technology to more efficiently track and manage your fleet, there’s more good news. You can increase driver productivity and avoid the 20-40 minutes per truck per day that’s lost through clocking in and out and other non-productive activities during: ·         Time in Transit ·         Time at the Job Site ·         Time in the Yard Forty minutes per day, per truck may seem marginal at first glance. But 200 minutes/week x 48 weeks/ year = 9,600 minutes, 160 hours or a total of 4,000 hours of inefficiency for a fleet of 25 trucks. Time in the yard is the lever most within a producer’s control and represents over half of the total nonproductive time per truck. So, rather than simply adding incremental trucks and drivers to the fleet to boost productivity (which unfortunately only adds to the total non‐productive hours and fails to improve operational processes), consider a solution that: ·         Uses automatic processes via technology to more efficiently track and manage your fleet. ·         Enables your drivers to punch the clock from in the cab, an efficiency enhancer that alone could save you up to 20 minutes per day (this is time spent in your own yard, under your own watch, that you can act on quickly to recapture those minutes, regardless of what happens away from your yard). ·         Captures a meaningful portion of that lost time from each driver. ·         Provides a constant view into the location and performance of your entire fleet. ·         Is adaptable and helps your teams collaborate in real-time with a “central source of truth” and access to relevant data when you need it. At least 50% of employees’ non‐productive time can be captured back efficiently and effectively when the right combinations of levers are pulled – both in terms of area of focus (i.e., time in yard) and adaptability to each individual customer’s business process requirements. This equates to big productivity increases over both the short- and long-term.

Is Your Jobsite a Wasteland? Check Out These 3.5 Ways to Reduce Waste and Costs
Command Alkon
No, I’m not talking about piles of leftover debris or even the kind of “trashy” look that’s common on construction sites. While neatness is nice, especially on a highly visible site, the waste I’m referring to is all those insidious, sometimes hidden, wastes that may not look messy but can make a real mess of budget forecasts and construction schedules.Jobsite waste – and the losses it creates – is a serious problem throughout the HBM industry. In fact, according to a 2016 McKinsey study, “Large projects across asset classes typically take 20 percent longer to finish than scheduled and are up to 80 percent over budget.”Most budget overruns are not the result of leftovers or throwaways. Most are a result of squandering 1) time, 2) motion, and/or 3) accuracy. Eliminating waste is an ongoing challenge, but these best practices can help you recognize – and correct – this resource-draining scourge:1) TIME. Wasting time is probably the most common and costly jobsite activity, especially since it’s virtually always unintentional and unobtrusive. What’s the best way to spot it? Recognize that all wait time is wasted time. Any person, place or thing that sits idle or is not ready when needed is generating waste.When workers wait on instructions or tools or equipment or approval or inspection, their time is being wasted. When tools, parts or equipment are unavailable or inoperable, time is being wasted. When one process or procedure is stalled waiting for another to be completed, valuable time is being wasted.Wasted time typically results from inadequate planning, communication or resource allocation, so invest in these time-saving, preventive measures instead:·         Begin with informed planning that includes all pertinent people. Early integration and transparent information sharing improve efficiency at every operational stage.·         Forecast construction schedules, budgets and requirements so that you can realistically anticipate tools, materials and labor.·         Create and communicate contingency plans so that the entire crew stays up to date and in sync.·         Use technology to communicate.  Radios, mobile phones, tablets and other digital tools speed communication and improve clarity.2) MOTION. Going back to the truck to grab another tool, hunting down a colleague for collaboration, moving critical materials or machinery from its current location to where it’s needed, dispatching and transporting workers, even unloading deliveries and distributing parts are all costly operations that reduce productivity. Any unnecessary or unplanned movement of people, equipment, tools or materials wastes valuable time and energy.To minimize wasted motion, use efficient workplace procedures and productivity-enhancing devices:·         Plan ahead to place and prepare critical equipment for use at the point of operation.·         Corral required tools, parts, kits and equipment in well-stocked, well-organized, well-maintained work carts. ·         Equip workers with tool belts, trays, bins and pouches for easy accessibility.·         Use rail-lock aerial accessories (tool bins, pipe racks, cradles, panel carriers, etc.) when working on scissor lifts, boom lifts or other platforms for safe, secure, fast access.·         Use communications technology to locate misplaced or misappropriated resources. ·         Designate a worker to make deliveries and tools runs as needed.3) ACCURACY. Precision in quality control, inventory management, and maintenance and replacement programs is vital for preventing wasted materials and labor. Symptoms of sloppy jobsite practices include tasks that can’t be done due to damaged, defective or missing materials; rework due to poor quality or specification mismatches; “shrink” due to lost or stolen tools or inventory; breakage due to careless handling or improper use; and mistakes in ordering, stocking, storing, handling and accounting for materials.Verifying resources and quality takes attention and vigilance. These common-sense practices can bring valuable order and discipline to your jobsite: ·         Make sure all workers have a clear project understanding, including the latest drawings, specifications and contingency plans.·         Lock up tools and equipment at days’ end and when not in use.·         Remove and replace damaged tools or materials immediately.·         Designate a specific person to order, inspect, label and monitor materials, especially near job’s end, to avoid leftover inventory.Are time and resources going to waste on your jobsite? Command Alkon helps make fast work of unnecessary jobsite losses.

Is Your Jobsite a Wasteland? Check Out These 3.5 Ways to Reduce Waste and Costs
Command Alkon
                  No, I’m not talking about piles of leftover debris or even the kind of “trashy” look that’s common on construction sites. While neatness is nice, especially on a highly visible site, the waste I’m referring to is all those insidious, sometimes hidden, wastes that may not look messy but can make a real mess of budget forecasts and construction schedules.Jobsite waste – and the losses it creates – is a serious problem throughout the HBM industry. In fact, according to a 2016 McKinsey study, “Large projects across asset classes typically take 20 percent longer to finish than scheduled and are up to 80 percent over budget.”Most budget overruns are not the result of leftovers or throwaways. Most are a result of squandering 1) time, 2) motion, and/or 3) accuracy. Eliminating waste is an ongoing challenge, but these best practices can help you recognize – and correct – this resource-draining scourge:1) TIME. Wasting time is probably the most common and costly jobsite activity, especially since it’s virtually always unintentional and unobtrusive. What’s the best way to spot it? Recognize that all wait time is wasted time. Any person, place or thing that sits idle or is not ready when needed is generating waste.When workers wait on instructions or tools or equipment or approval or inspection, their time is being wasted. When tools, parts or equipment are unavailable or inoperable, time is being wasted. When one process or procedure is stalled waiting for another to be completed, valuable time is being wasted.Wasted time typically results from inadequate planning, communication or resource allocation, so invest in these timesaving preventive measures instead:1) TIME.

When tools, parts or equipment are unavailable or inoperable, time is being wasted. When one process or procedure is stalled waiting for another to be completed, valuable time is being wasted.Wasted time typically results from inadequate planning, communication or resource allocation, so invest in these timesaving preventive measures instead:Begin with informed planning that includes all pertinent people. Early integration and transparent information sharing improve efficiency at every operational stage.Forecast construction schedules, budgets and requirements so that you can realistically anticipate tools, materials and labor.Create and communicate contingency plans so that the entire crew stays up to date and in sync.Use technology to communicate.  Radios, mobile phones, tablets and other digital tools speed communication and improve clarity. 2) MOTION. Going back to the truck to grab another tool, hunting down a colleague for collaboration, moving critical materials or machinery from its current location to where it’s needed, dispatching and transporting workers, even unloading deliveries and distributing parts are all costly operations that reduce productivity. Any unnecessary or unplanned movement of people, equipment, tools or materials wastes valuable time and energy.To minimize wasted motion, use efficient workplace procedures and productivity-enhancing devices:Plan ahead to place and prepare critical equipment for use at the point of operation.Corral required tools, parts, kits and equipment in well-stocked, well-organized, well-maintained work carts.Equip workers with tool belts, trays, bins and pouches for easy accessibility.Use rail-lock aerial accessories (tool bins, pipe racks, cradles, panel carriers, etc.) when working on scissor lifts, boom lifts or other platforms for safe, secure, fast access.Use communications technology to locate misplaced or misappropriated resources.Designate a worker to make deliveries and tools runs as needed.3) ACCURACY. Precision in quality control, inventory management, and maintenance and replacement programs is vital for preventing wasted materials and labor. Symptoms of sloppy jobsite practices include tasks that can’t be done due to damaged, defective or missing materials; rework due to poor quality or specification mismatches; “shrink” due to lost or stolen tools or inventory; breakage due to careless handling or improper use; and mistakes in ordering, stocking, storing, handling and accounting for materials.Verifying resources and quality takes attention and vigilance. These common-sense practices can bring valuable order and discipline to your jobsite:Make sure all workers have a clear project understanding, including the latest drawings, specifications and contingency plans.Lock up tools and equipment at days’ end and when not in use.Remove and replace damaged tools or materials immediately.Designate a specific person to order, inspect, label and monitor materials, especially near job’s end, to avoid leftover inventory.Are time and resources going to waste on your bsite?

Get More Performance Out Of Your Crusher
Stedman Machine Company
Get More Performance Out Of Your Crusher impactor maintenanceThere’s an urban legend out there about the company whose maintenance crew mistakenly installed a new crusher with the rotor spinning backwards. It still worked! And you think you have issues? To get the most from your equipment investment, you need to put in the time. Yes, a crusher costs a bit more than your average automobile, but that doesn’t mean it’s maintenance-free. An automobile needs oil changes too, right? Performing regularly scheduled maintenance on impact crushers is crucial for guaranteeing day-to-day reliability and optimum product output. Did you know you can boost output and quality by doing just a little bit more? Even daily cleanups and inspections can increase service life. It’s a no-brainer, though possibly easier said than done. Here are some steps and practices to incorporate in your ongoing operations and maintenance. Beginning with maintenance team education, parts logs, and general maintenance record keeping, plus troubleshooting, these guidelines will help your crusher go the distance. Training: Proper training for consistent maintenance is one of the most fundamental requirements for successful, reliable production. Begin with the crusher’s operation and maintenance manual. Incorporate the manual’s suggested routine maintenance schedule into the maintenance team’s duties. Appoint a “lead person” for each crusher as the go-to for that machine. This person is the historian for the unique operational adjustments the producer has incorporated for raw feed and product requirements. Daily log (document the following every 8 hours): Amperage draw: See if it changes from day to day. If amperage is exceeding normal levels, it could be a signal of bearing problems, loose belts, or general feed issues. Coast-down time: You’re going to need to know (and log) how long it takes the machine to come to a complete stop after shutdown. Here’s why: If the time starts to shorten, this could indicate a bearing problem. Oil pressure: You’ll want to record performance in a variety of operating conditions. This will allow you to identify trends and help to detect problems before they cause costly damage or downtime. Daily maintenance (every 8 hours): Check oil level, sight glass, grease appearance, and other lubrication schedules. Check high temperature or low hydraulic pressure indicators and switches. Check wear parts. Tighten bolts. Inspect belts. Remove dirt and debris from crusher frame surfaces and areas around the machine. Check intake/discharge chutes for any obstructions and/or build up. Check alarms. If electrical changes are made or programs are altered in automated systems, verify that all alarms and interlocks function properly. Don’t be afraid to replace switches or timers that appear damaged or are in poor condition. This is more economical than a major overhaul, but never disable or alter any alarms or interlocks! Lubrication: Completely drain and thoroughly clean out the inside of the oil tank (if you have one) to eliminate any contaminants before refilling. Find contaminant sources. Contaminants such as dust particles and water can get in where oil leaks out. Inspect hydraulic systems and tag any leaks for corrective action on the very next maintenance cycle. Use the proper grade of oil. Use the proper specification of filters. Keep the oil breathers clean. Understand grease versus oil lubrication. Grease requires less-intensive maintenance than that of oil-lubricated systems. Automatic oil lubrication systems or sealed cartridge bearings are for higher speed crushers like vertical shaft impactors, air swept fine grinders, or high-speed cage mills. Most horizontal shaft impactors, hammer mills, and cage mill applications are below 1,000 rpm and grease is sufficient. Maintain a scheduled oil sampling program. By creating a baseline of normal wear, it helps indicate when abnormal wear or contamination is occurring. The exact condition of a mechanical assembly is reflected in the oil. Belts: Inspect V-belt drives for damaged belts or loose belt tension. By replacing cracked, glazed, torn, or separated belts, plus maintaining proper belt tension, you’ll optimize your plant’s performance. Wear parts: Don’t overextend wear parts. Avoid running them so long that they become too worn. You may find that you can no longer rotate breaker bars or interchange wear plates to lower wear areas — and now, you’ve lost half of the wear. Guards: Rubber and chain curtains located in the feed and discharge openings of the crusher are subject to wear and tear. Since they are a first line of protection, it’s important to inspect them regularly and to establish a schedule of regular maintenance. Electrical: When (or if) electrical changes are made, you’ll need to verify that all alarms and interlocks still properly function. Same goes for programs when altered in automated systems. Always check with the manufacturer before making any modifications. Spares recommendation: Keep the recommended spares on hand and order replacements as soon as they are used. A list of recommended spares may be included with your equipment operations manual. If not, contact the manufacturer for recommendations. Update your equipment: All equipment evolves, and the recommended manufacturer upgrades are a good investment for increased life and better crusher performance. Check with the manufacturer for any possible updates. Unapproved modifications: Manufacturer design engineers have considerable field experience, which helps them as they calculate the design and perform prototype testing. Their engineering tasks include calculating bearing loads and bearing clearances. They’ve also worked to maximize throughput by establishing the most efficient speed and setting combinations to optimize impact on the material undergoing reduction. So when plant personnel suggest modifications that alter the intended design, these changes will more than likely hurt the purpose of the original design. As a result, you’ll have a less productive and reliable crusher due to potential damage and overload. Since the manufacturer has a vested interest in how well the crusher performs, contact them before making any modifications Cage Mill Operation and Maintenance Requirements for optimum production and wear part utilization include the following: sleeve wear patterns cage wear pattern identification To increase multi-cage sleeve life, cage rotation should be reversed regularly, if possible. (Some cage mills can be reversed, while others cannot.) By reversing the cage direction, sleeves will be worn from both sides, thus extending wear life. Wear parts: Index and or replace sleeves periodically. Inspect or replace hopper ring and shaft protector, if needed. Cage rebuilding is an option. Bearings: Follow the manufacturer’s recommended specifications and schedule for lubrications, temperature, and vibration ranges of spherical roller bearings in pillow block housings. Horizontal Shaft Impactor Operation and Maintenance Variables affecting product gradation include the following: Rotor speed – Higher rotor speeds produce finer product output.Breaker bar wear & new edges crush finerBreaker bar changes. Apron gap settings – Closer gaps retain the feed longer producing a finer product. Breaker bar wear – Regular inspection and turning will lower operating costs. Throughput (tons per hour) – Overfeeding a crusher can make the output more coarse, but it also causes a number of wear and longevity issues making overfeeding a major concern to avoid. Moisture – Moisture cushions the impact, producing a coarser product. Apron wear – Worn plates can be replaced or moved to areas of lower wear. Spring bridge operation – Spring set height is critical to maintain proper operation of spring bridges. Spring bridges return the aprons to their original positions after an overload situation. The use of altered or non-specified springs can cause equipment damage or catastrophic failure. Requirements for optimum production and wear part utilization include the following: Protect inlet and outlet. Restrict maximum feed size. Maintain feed rate within allowable limits. Check rotor rotation. Use metal detection (required). Check for wear. Follow recommended breaker bar rotation setting sequence. Check rotor breaker bar, wedge, and stop block or jack screws. Check liners and breaker plates. Vertical Shaft Impactor Operation And Maintenance The vertical shaft impactor uses high rotor speeds (1,000 to 3,000 rpm) to apply high energies to the material, and since Energy + Material = Size Reduction, it can create sand from 2-inch feed. Requirements for optimum production and wear part utilization include the following: optimized parts in rotor tube Limit feed size. Use metal detection (required). Observe any vibrations with the use of continuously monitored vibration sensors. Listen to the equipment, if something sounds unusual, shut down and inspect. Limit recirculating product in a closed system. If using water for dust suppression, introduce it into the discharge area if possible. Introducing water in the intake will increase wear. Place weight match shoes opposite one another. The image above shows rotor tubes indexed 90 degrees providing a new wear surface. Wear parts include the following:recommended parts for vertical shaft impactors Shoes and tubes Anvil ring or other inserts Housing liners Rotor table liners and assembly Spares recommendation: Shoes (one complete set) Table liner Anvils (one complete set) Discharge plate The spare parts inventory shown above is recommended for vertical shaft impactors. Hammer Mill operation and Maintenance Up running hammer mills combine impact and shear to reduce material. Down running hammer mills primarily use shear by immediately taking feed to the screen or grate bars where hammers shear the material, until it passes through the openings. Requirements for optimum production and wear part utilization include the following: Lubricate bearings regularly. Regularly inspection (unclamp or unbolt front upper half housing for access to screens and hammers) liners, hammers, hammer bolts, rotor discs, grate bars, and screens. Spares recommendation: Hammers Screens Liners Grinding plate Summary A partnership begins between the manufacturer and the customer when the crusher is installed in the field. The manufacturer needs the customer’s help as much as the customer needs the manufacturer’s help to achieve the highest performance possible. Maintenance service after the sale, although mentioned last, is a central part of crusher system performance. And just in case, the manufacturer will have the people and the parts available 24/7 to assist with any problems. Regardless of the field application, the training of personnel is key to successfully and optimally operating equipment. For the size-reduction industry, crusher maintenance problems are mostly related to inadequate training. This exists at plants both large and small. The most effective education is a current and ongoing program for crews — and that’s what will result in legendary performance.
All You Need to Know About: Vertical Shaft Impactor (VSI) Primers
Stedman Machine Company
All You Need to Know About: Vertical Shaft Impactor (VSI) Primers By Eric Marcotte, Inside Sales Manager, Stedman Machine Company Vertical Shaft Impactor What Is VSI? All roads, you might say, lead to the Vertical Shaft Impactor (VSI) because these crushers make it possible to create roadways and just about everything else. Francis E. Agnew of California patented one of the first Vertical Shaft Impactors in 1927. His configuration stacked three VSIs atop each other to produce sand, thus starting the VSI evolution. Today, VSI crushers – and the folks who rely on them – have produced many configurations to include everything from the addition of cascading material into the crushing chamber, to air swept separation of lighter product. One version suspends the shaft from above like a sugar centrifuge. It’s also one of the most feature-patented crushers, so some of the things mentioned here might be unique to a single manufacturer. VSIs apply a large amount of energy to crush material and that’s why it’s one of the most versatile crusher configurations today. View our VSI Machine Specifications, and get a quote today! VSI Benefits When it comes to producing materials such as aggregate for road making, VSI crushers use a high-speed rotor and anvils for impact crushing rather than compression force for the energy needed for size reduction. In a VSI, material is accelerated by centrifugal force by a rotor against the outer anvil ring, it then fractures and breaks along natural faults throughout the rock or minerals. The product is generally of a consistent cubical shape, making it excellent for modern Superpave highway asphalt applications. The rotor speed (feet per minute) controls final particle size. The VSI’s high cubical fracture percentage maximizes first-pass product yield and produces tighter particle size distribution. It has a high-throughput capacity ideal for beneficiation (elimination of soft material). Properly configured the VSI accepts highly abrasive materials. It has simple operation and maintenance. You can quickly change product size by changing rotor speed or cascade ratio. Some models have reversible wear parts to reduce downtime. The VSI typically has low operating costs even in high-moisture applications because of reduced energy costs and low wear cost per ton. VSI Disadvantages There are some feed size limitations with a VSI because of the small feed area available in the center of the rotor. Tramp material in the feed such as gloves, tools, etc. can cause problems with imbalance. The high RPM and HP require careful balance maintenance such as replacing shoes on both sides of the rotor at the same time. High wear part cost may be a problem for some hard abrasive materials, but the VSI may still be the best option. VSI Applications Major limestone applications are for Superpave asphalt aggregates, road base, gravel, sand and cement. Industrial uses include: corundum, corundite, ferro silicon, glass, refractories, silicon carbide, tungsten carbide and zeolite. Mining applications include: bauxite, burnt magnesite, iron ore, non-ferrous metal ore, perlite and trona sulfate. VSIs are excellent for everything from abrasive materials to waste and recycling applications. Verticl Shaft Crushers VSI Crushing Method The VSI is typically used after a primary or secondary crusher. This makes a VSI ideal for making sand and for making coarse and medium aggregates for concrete/asphalt production. Feed size and characteristics will affect the application of a VSI. The feed size is limited by the opening in the center of the rotor. Normally less than 5-inch material is desired, but very large VSIs can handle up to 12-inch feed. Another feature that will affect application is moisture, which can make the feed sticky. Required production capacity is the final limiting criteria. Large primary horizontal shaft impactors can output up to 1600 TPH and more. 1000 TPH is about the maximum for a VSI because of the limiting motor size and the rising G-force of a high-speed rotor, which is calculated by multiplying the radius times the square of the RPM. Shoe configurations are many: rock on rock, groups of rollers, special tip wear parts and many others. The metallurgy of the shoes is also highly varied. Rotors can have three to six shoes. The number of shoes is typically governed by the diameter of the rotor. The larger the diameter rotor, the more openings are possible. Computational Fluid Dynamics (CFD) mathematical models are utilized to simulate the flow and collision forces to reveal solutions for lower wear cost, consistent final product, and higher energy efficiency. The material to be crushed is fed into the center of an open or closed rotor. The rotor rotates at high rpm, accelerating the feed and throwing it with high energy into the crushing chamber. When the material hits the anvil ring assembly, it shatters, and then the cubical shaped product falls through the opening between the rotor and the anvil and down to the conveyor below. The rotor speed (feet per minute) controls final particle size. Speeding up the rotor will produce more fines, slowing it down will produce fewer fines. Feeding Methods Center feed The typical VSI is fed, from above, into the center of its rotor. The material is then flung across an open void to the crushing chamber. It then impacts the outer anvil ring. This crushing action imparts very high energy to the material and is very effective on most types of material. It gives a very uniform and consistent grade of product. Cascade feeding V-Slam Impactors In cascade feeding, material bypasses the rotor and enters the crushing chamber from above. It’s called cascade feeding because as material fills up a large feed bowl, with an outer diameter larger than the outer diameter of the rotor, it spills over the side and falls into the crushing chamber from above, bypassing the rotor. The effect of increasing feed through cascade is similar to slowing the rotor. Cascade feeding in amounts up to 10 percent may have no effect on particle size distribution or quality. The product gradation curve and product shape will change, if an increased amount of cascade feeding is used. Vertical Shaft Impactor for Aggregates (Above: Vertical Shaft Impactor, No Cascade vs. With Cascade Feed, Particle Size Distribution Chart) Rotor and Anvil Configurations The VSI features multiple rotor/anvil configurations for various applications. From open or enclosed rotors to the tubular rotor, each machine is configured for their unique application. In many cases the rotor table, rotor assemblies, anvil ring or rock shelf are interchangeable, allowing maximum application flexibility. Crushers for Aggregate Industry Open top metal rotor shoe on metal anvil The open top metal rotor is good for large feed or medium to very hard material, but it will work best for softer materials. It can handle medium abrasive, dry or wet, but not sticky materials. High reduction ratios are common, which are excellent for sand and gravel production in closed loop systems. Shoe shape can change the production size range. A straight shoe face design produces finer product, and a curved shoe face design produces coarser material. Stedman VSI Impactor Tubular metal rotor shoe on metal anvil The tubular rotor creates higher tip-speeds, which increases first pass yield with tighter particle size distribution and also reduces the recirculation loads. One unique feature is that the rotor rotation is reversible, allowing wear on both sides of the tube. Rotating the tube itself one-quarter turn also doubles the wear. Vertical Shaft Impactor Benefits Enclosed metal rotor shoe on metal anvil The enclosed top plate on a rotor primarily prevents material from escaping from the top of the rotor, which could happen with an overfed open top rotor. Vertical Shaft Impactor Applications VSI Crushers (Above: Rock shelf when VSI at rest. In operation, the brown rock fills the chamber to the upper roof ring. Rock impacts rock in operation.) Enclosed autogenous rock rotor table on autogenous rock shelf Any time the material or rock is used as an impact wear surface the term autogenous is used. Putting a top on the rotor table and shoes allows autogenous use. During operation of the VSI, a bed of material can be designed to build up inside the rotor against each of the shoe wall segments. The bed, which is made up of material that has been fed to the rotor, extends to a wear tip. The bed protects the shoe wall segment from wear. Concerning the rock shelf anvil, it forms a near vertical wall of material upon which the accelerated material impacts. “Rock-on-rock” crushing reduces maintenance but can require up to 30 percent of material recirculation before meeting size requirements. Also, the rock shelf anvil absorbs energy that could otherwise be used for breaking, which may reduce efficiency. More RPM may be needed to achieve the same result as a solid metal anvil. Good for medium abrasive materials, rock-on-rock configurations of either or both rotor and anvil may produce consistent material with low-wear cost and can handle wet but not sticky conditions. Reduction ratios from 2:1 to 5:1 can be expected. It’s widely used for quarried materials, such as sand and gravel. Due to the many configurations of the VSI feed, rotor, anvil and open- or closed- system design; testing is the only way to ensure proper application of a VSI crusher. V-Slam Supplier Summary The VSI is one of the most versatile crushers available on the market today. Even with some limitations, like feed size and output capacity, VSI features have been and continue to be developed to maximize first-pass yields and lower operating costs. If you test your process on full-scale equipment before choosing your VSI, you won’t be disappointed.

Expect More from your Horizontal Shaft Impactor
Stedman Machine Company
By Eric Marcotte The mineral processing industry usually evolves rather than revolutionizes, but the Horizontal Shaft Impactor (HSI) has revolutionized the crushing process in numerous industries.32 IMPACTOR 400 There are several varieties of the HSI, and their similarities are more numerous than their differences. All varieties feature externally fed horizontal rotors with breaker bars, which propel material into a series of apron-mounted breaker plates that crush or pulverize many different types of materials to specified degrees of fineness. In 1946, Dr. Erhard Andreas of Muenster, Germany, patented the “Andreas Impact Crusher System.” His design utilized old torpedo tubes and steel from decommissioned tanks. Since then, there have been many unique features of the design patented, but they all operate similarly. This article reviews current techniques employed to get the most from this versatile design. Versatility Reduction ratios of up to 30:1 are achievable in a single stage. The simple design offers low capital and operating cost. Low headroom requirements make it easy to install. Product sizes may be varied by changing rotor speed and the clearances between rotor breaker bars (also called blow bars or hammers) and apron breaker plates. HSI applications have gone beyond soft and nonabrasive materials such as limestone, phosphate, gypsum and weathered shales, to harder minerals thanks to the introduction of alloy steel rotor breaker bars. Typical alloy steels contain manganese and/or high or medium chromium content. There are many different crushing chamber designs on the market, and proper selection will depend on the knowledge of the application for proper feed, crushing chamber configuration, metallurgy of the crushing chamber components, gap setting and rotational speed. Finally, computer controls can automatically adjust HSI settings on the fly to adjust for wear or changing specs. Operation HSIs have a lined crushing chamber with rotating breaker bar rotor on a horizontal axis. The size reduction takes place quickly along short fracture lines, producing a more cubical product to meet aggregate specifications. This fast impact fracture is different from the slow compression breaking in cone or jaw crushers that produce more slabby or flat material (5:1 length to height ratio). 32 IMPACTOR2 400Feed enters the primary crushing chamber and meets the rotor breaker bars, which impel the feed against the first apron lined with breaker plates. Impact with the rotor, the breaker plate, and inter-particulate collision all contribute to comminution. Material is reduced in the primary chamber and passes by the front apron breaker plate gap, entering the secondary and, in some configurations, tertiary chambers, for final reduction. A high percentage of the initial size reduction comes from the first impact with the rotor breaker bar. Aprons are shaft suspended at the front and from a spindle in the rear, allowing for continuous gap adjustment as wear progresses. Unlike hammer mills, the open discharge impactor has no screens or grates holding material inside the crusher; material is efficiently processed at high rates for low costs. The rotor breaker bars operate best at specific speed ranges for maximum results. As the total processing capacity and rotors get larger, the number of breaker bar rows increases. On smaller sizes, there are only two rows; on larger rotors, there are four or more rows of rotor breaker bars. The optimum configuration has material delivered to each row of rotor breaker bars in a continuous bed over the width of the rotor for optimum performance and consistent wear part utilization. Some rotor interiors are open, and some are closed depending on feed conditions. For example, concrete recycling requires a closed rotor so rebar doesn’t get entangled. Application The HSI is used for all types of material with compressive strength less than about 20,000 lb. per sq. in. It’s widely used for sand and rock for roads, railways, reservoirs, electrical grid isolation, building materials and many industrial applications such as metal reclamation and recycling.34 IMPACTOR3 400 Wear part metallurgy is critical to proper applications and performance. It’s a good idea to keep a log of these items to determine the best wear part selection and maintenance schedule: feed and discharge information, throughput rates, change out records and measurements of worn parts. Proper selection of wear part metallurgy will result in optimum production rates; longer maintenance cycles and fewer changeouts, which reduce costs in labor, increase the wear part’s life as well as reduce downtime. Materials with high moisture content can be successfully handled by using heaters and air cannons to reduce and dislodge material adhering to the crushing components and chamber. Size Control The spacing between rotor breaker bars and breaker plate aprons can be adjusted to produce different products within one crusher. It is possible to crush soft raw material limestone or high-grade harder limestone for cement or asphalt applications with one crusher by externally adjusting the breaker bar and plate settings. Gap adjustment between the rotor breaker bars and breaker plates by manual or computer controlled systems adjusts the crushing gap so that product particle size distribution remains constant. Maintenance HSIs have multi-turn breaker bars for extended life before changeout. Design simplicity offers safe and easy access for breaker bar replacement and access to all areas of the crushing chamber. Front-opening models eliminate the need for a crane in some cases. Rear-opening models can allow unique installation applications. Summary 34 IMPACTOR 400 HSIs have evolved from humble beginnings through improved crushing chamber design and metallurgy advancements to automation controls. HSIs have proven they are capable of size reduction of all types of material sizes and hardness with minimal maintenance and excellent cubical particle size distribution control.

MacLean Innovation Report 2018 - Changing the face of the mining industry
MacLean Engineering
Sometimes a turning point can only be seen clearly in hindsight. Such is the case for the mine of the future as we begin 2018, coming out of a 2017 where major mining companies continued to demonstrate capital spending austerity and focus on debt reduction. All the while, there were growing signals that digitalization, electrification and automation were all gaining momentum, even though actual examples of minesite implementations could as of yet, still be counted on one hand. MacLean took the opportunity that industry downturn presented over the past several years to focus intensely on three key product development ventures – first and foremost, the battery electrification of our entire fleet, which will be complete by the end of 2018; second, the successful introduction of face bolting as a feature on our 975 Omnia bolter; and, third, the launch of the latest addition to our utility vehicle product line – the LR3 Boom Lift for heavy load and high reach applications. The past year was one where for the first time we had a fleet of battery electric vehicles working underground, allowing us the ability to validate our performance and total cost of ownership (TCO) models with real-world data, while at the same time continuing to build out our EV offer across the product lines. Looking forward, as we work hard to fully electrify our fleet of ground support, ore flow/secondary reduction, and utility vehicles, we’re keenly aware that electrification is but one step in the ongoing mechanization of underground mining, a transition to the mine of the future that will be increasingly efficient through digitalization and automation that will increase production and reduce costs.
Making Equipment Replacement Decisions
PAUL D TOMLINGSON
Competition among industries has become globally oriented. Thus, every industry will be examining how they can become more profitable. Increasing the productivity of equipment will be among the logical steps. In turn, older, less productive equipment will be replaced. Modern production equipment will be expensive as well as more complex. Thus, as new capital outlays are considered, there must be more careful consideration than ever before. The singular economic approach to replacing equipment involving primarily accounting personnel must give way to a company team approach. To assure that the best equipment for the job at the best price is purchased, economic as well as performance considerations must be weighed. Maintenance is especially sensitive to this requirement since the new equipment is likely to have many new technological advances that will make it more difficult to maintain. Thus, new maintenance techniques must be introduced and maintenance personnel must be properly trained in applying these techniques. Therefore, plant managers should provide policies that ensure each department recommends features of the new equipment that impact performance and maintenance. Although decisions must embrace performance and maintenance, acquisition cost and long term capital expenses remain an important ingredient. Then, as team decisions are made, there will be better assurance that the right choices are made and that the equipment will effectively support the productivity and profitability requirements of the future
Why Simulation?
IMMERSIVE TECHNOLOGIES
Simulation based operator training has been successfully applied to a range of diverse industries where high risk and high costs are everyday issues requiring smart solutions. Whether piloting a plane or launching a space shuttle, simulation training has been proven to dramatically reduce risk, cost, unscheduled maintenance, increase trainer effectiveness and efficiency while maximizing productivity. Within the often hazardous mining industry, simulation training has quickly gained recognition as a significant method of increasing site safety and profitability through improved operator skill and knowledge. Simulators provide operators a safe environment to learn and practice their skills while allowing the operator to practice for a range of possible emergency situations. Many of these situations are too dangerous, too difficult or too expensive to test in an actual mine. Operators can also be shown and assessed for the proper operating technique much more quickly and accurately than the traditional in machine approach. Focus on improving operator technique with Immersive Technologies’ simulators has delivered proven results including longer tire life, reduced spot time, reduced brake abuse, improvements in fuel use, reduction in engine overspeeds and more. Simulator training allows operators to be shown and assessed without the need to borrow machines from production. This allows new operators to practice many skills before being placed into a production circuit. Because operators are consistently shown and assessed on the proper operator techniques they have a better understanding and knowledge of the real machine. Following Immersive Technologies release of the world’s first mining dump truck simulator in 1998, their customer results, support network, machine range, global mining footprint, level of realism and OEM endorsements are without equal in the industry. Highlighting the benefits of simulation training, four leading Original Equipment Manufacturers, Caterpillar, Hitachi, Komatsu and Liebherr have chosen to exclusively sign technical information licensing agreements with Immersive Technologies, providing access to proprietary technical information necessary to accurately replicate the operation of their mining equipment.
