It will take more than pay increases to attract new drivers. Rather than harping onneeding more trucks and drivers, a new approach needs to be taken to determine asolution for the existing problems; the industry needs to consider ways to better utilizeexisting trucks and drivers.

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.                   

This year has truly blown by. It’s hard to believe that it’s already August – which means it’s practically Christmas, right? I have a very large family, so usually around this time is when I start to budget and plan for Christmas shopping. I have a difficult time in large crowds, so the hustle and bustle of Christmas shopping in the mall isn’t my thing whatsoever. I prefer staying home in my PJs and shopping around on my favorite app – Amazon. Despite my early jump on the holidays, there are ALWAYS those few friends or family members that I forget about – perfect opportunity for Amazon! While I’m shopping around for a gift, the app gives me an estimate of when my goods will be delivered before I hit “purchase.” Real-time tracking gives me peace of mind to know that everything I ordered will be here before Christmas. Business is all about the customer: what the customer wants and what they get. I’m always a very satisfied customer when I use Amazon, and that’s why I continue to do so. I love constantly receiving information about the goods that I’ve purchased and having confidence that they will be delivered to me when I need them. What if you could also provide your customers with an experience that sets you apart from your competition? What if you too could offer a way for your customers to feel empowered during the order and delivery process? MOBILEjobsite can work for your business in ways that Amazon works for me. Your customer can receive dispatch data in real-time, regardless of their location. Like my Amazon app, this tool is an easy-to-navigate app that gives the user information on orders scheduled for today, upcoming orders for future days, real-time truck locations, load-level summaries of completed and upcoming orders, notifications when a load is on the way to your site, and records of load status times. A consumer survey conducted by Convey, a team of supply chain and technology professionals, showed that the customer forms impressions about the brand throughout the purchase experience, and these impressions are reaffirmed or destroyed by the experience they receive through the delivery process. To succeed, customer loyalty must be a core focus. Gain a competitive advantage by efficiently improving the delivery experience.

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.

Teamwork Helps Integrate Design, Manufacture and Installation of Size- Reduction Systems By Eric Marcotte, Inside Sales Manager, Stedman Machine Company Designing and deploying size-reduction systems takes experience. Many people can collect and install some of the pieces they feel are needed to create a working system, but experience with the interrelationships between components is harder to find. And to ensure safety and performance, crushing, screening, storage and handling systems need to be professionally engineered. A system is always more than just a collection of parts; they must work together whether it’s a properly designed chute or an elaborate processing plant. Retrofitting new crushers, conveyors, screens or other pieces of equipment is also not always an easy process. Even if drawings and specifications no longer exist, plant designers need to make sense of what is there and know what it takes to make new pieces fit in an existing puzzle. If continuing production during the upgrade is required, system bottlenecks will need to be prevented. For example, raw material or finished product stockpiles may be required to keep downtime to a minimum. Also, access and space requirements need to be confirmed and double-checked. First - Assemble a Team Engineering and expertise in a variety of areas are required to develop size reduction systems, including: crushing, screening, structures, conveyors, chutes, hoppers, dust collection and storage, whether for a small equipment retrofit or a large turnkey facility. CAD and process design software applications are must have. Limit multiple layers of personnel. Work directly with the engineers and personnel to select the equipment and design the system. Project management, installation, scheduling and tracking experience will be needed. Be sure supervisors and installers are MSHA trained and have experience in fieldwork. Second - Process Design While most projects present new challenges, a widely experienced team will bring in ideas from other industries. Typical projects involve the following processes and types of equipment. industrial crusher Load out and material receiving This can be a feed hopper with an apron feeder, belt feeder, vibratory or screw feeder, truck dump or railcar unloading system. Bulk material transportation Designing, building or procuring belt conveyors, stackers, apron conveyors, screw conveyors, and pneumatic handling conveyors. Crushing Crushing is the basic building block of a size-reduction system. Experience with a large range of crushing equipment offers many solutions. Properly feeding material into the crusher greatly increases its efficiency, contributes to even wear and maximizes wear metal costs. Bulk material storage Specifying, providing and installing a range of silos, hoppers or other bulk storage solutions. aggregate crusher Screening Experience with many screening manufacturers to include the right screening solution into the system. Dust Collection Including the proper dust collector and dust collection system is a key component to allow a crushing system to work properly. Experience with many dust collection vendors will facilitate properly sizing, connecting and installing the best dust-collection system solution. Controls and Electrical Components To make sure that all components of a system work together, work with control system engineers, panel builders and electrical contractors to create a working, integrated system. Buildings, Foundations and Structure Design, procurement and specifications for buildings, foundations and structures for the equipment supplied on any system. Third - How to Do It Every project has a different set of circumstances that are unique to it. Try to follow a simple checklist to ensure the best possible solutions to the problems. Initial project team meeting. Crusher and screening testing as required. Define required scope for the system. Create preliminary concepts and drawings. Review with operators and supervisors. After receiving feedback, fine-tune the drawings, concepts and put forth a detailed proposal. Set up kick off meetings as required. Proceed with the purchase of major components. Proceed with a detailed system arrangement. Detail major assemblies. Assemblies put out for detail drawing creation. Drawings are self-checked and then crosschecked for accuracy. Assemblies are re-entered into system layout from detail assemblies to verify fit. Approval drawings sent out as required. Vendor drawings checked and approved. Items checked as they are received. Work with vendors and shipping to verify shipment accuracy. Pictures are taken of all shipments for record purposes. Installation supervisor works with install crew to identify, locate and erect items as needed. As installation finish date nears, begin check of motor rotations, sensors etc. Final customer acceptance – formal reviews to finalize “punch list,” follow up items and document the system is performing as specified. Example - Typical Quarry Expansion A limestone quarry running since the 1950s and producing 500,000 tons per year wanted to increase yearly production capacity up to 1.5 million tons with a new automated plant. The new design needed to have the capability to stockpile hundreds of thousands of tons of finished product. The focus was on creating a state-of-the-art plant with designed-in flexibility to do different product sizing. The automated plant needed to have the ability to run production all day as well as to be able to change the product sizes within 10 minutes. The design and fabrication of a new plant may take up to two years to complete as each idea is considered and "wish lists" are sorted out. You don’t want to come back and say we should have done this or done that. Get the very best of everything you can get into the plant for longevity. The project will include numerous conveyors, sensors, controls, vibrating screens, feeders and other equipment. size reduction machine Installed electronics and control systems feed a programmable logic controller. Each conveyor at the plant is equipped with terminal strips that are all wired to communicate information to one main processor, bringing all of the information together in one place to make it easy to operate. All of the feeders and conveyors are monitored to collect all of the information required to operate the plant. With the ability to monitor the speed of the conveyors and feeders, the quarry can keep an eye on production and troubleshoot maintenance issues. The reason for having an automated control system is that if something goes wrong on one of the conveyors, you’ll see it fast enough to prevent a catastrophe that might require digging out a conveyor. If something does go wrong, the computer can take over and begin dropping conveyors, discharging material and shut the feeder down. Since the quarry can now monitor the conveyors moving, the speeds and the tons per hour, limitations can be set to help catch problems before they become too serious. If something is going wrong, say conveyor 2A is slowing down, you can put limits on how much you want to allow it to slow down before the feeder is paused and then limit how long that feeder stays paused. In the end, the quarry was able to more than double their production capacity with the help of the automated plant. The plant was built, delivered and installed as planned with no problems. This is an ideal situation if a quarry is sitting on huge reserves of limestone and plans to operate the crushing plant well into the future. Projects such as this are successful when the customer’s needs are defined and understood, and the project team – including the customer and all supplier partners work to accomplish the project goals.

In 2017, a large fire brought the interstate bridge 85 to collapse in Atlanta, Georgia. It became a transportation crisis for commuters and local residents so the Georgia DOT decided on accelerated construction techniques. The durability of bridge decks is severely compromised by shrinkage cracks which can lead to immediate access for water and deicing chemicals to the steel reinforcement and internal concrete. PREVent-C technology was selected to be used in an accelerated mix and a 3-day curing period versus a more standard 7-day curing period. When accelerated strength and minimal curing are used, cracking would be visible immediately following the end of curing. When the curing was removed from the 1-85 Bridge, there was no observance of cracking.

The East Columbia Basin Irrigation District in Othello, Washington, receives regulated water from the East Low Canal to irrigate agricultural land. Water is moved from basins, dams, and irrigation canals through concrete siphons. Signs of deterioration through cracking has occurred and rises complications such as water loss, eroded soil, and seeping of agricultural chemicals. All of these complications pose a threat to local environmental health and public safety. The East Columbia Basin Irrigation District chose PREVent-C when building two siphons which led to a 1 percent joint failure compared to 25 percent.

Echo Dam is a 158-foot high earthfill structure on the Weber River in Summit County, Utah. Inspections concluded that modifications needed to be implemented with concerns of soil liquefying during a seismic event causing deformation of the aged spillway structure. Challenges arose before the project started such as the required low slump, long transport distance, and project timeline. The US Bureau of Reclamation chose PREVent C to reduce shrinkage cracks, based on successful field trials from the past. The use of PREVent-C can allow an increase in joint spacing, since the potential for concrete shrinkage cracks is greatly reduced.

The Glen Elder Dam and Spillway is located in Kansas and originally built in 1968. The dam serves many purposes in order to control flooding and create the Waconda Lake which is used for municipal and irrigation water. In 2010, extensive repair and renovations occurred due to freeze-thaw damage which promoted alkali- silica reaction. When new concrete was placed, extensive shrinkage cracking occurred within the first seven days. PREVent-C was chosen as a trial admixture to evaluate its effectiveness on shrinkage cracking. After approval by the US Bureau of Reclamation, the results were impressive. Cracks were completely prevented in two of the test slabs and about 90% reduced in the third slab.

Liberty University in Lynchburg, Virginia built a new state-of-the-art natatorium that would measure up to 75,000 square feet. The facility is unique to the campus as it holds the largest diving platform in the United States and would be hosting USA swimming programs and national meets. Any crack in a pool is detrimental because a pool is meant to contain water and cracking can compromise the high-quality look and feel to it. PREVent-C provides controlled expansion resulting in volume stability creating 90 percent fewer cracks on average compared to standard concrete. Eight months after the project was completed, the results showed there were zero cracks.

The Intracoastal Way runs along the East Coast that helps shipping traffic in and out of the United States. In 2014, a seawall in Naples, Florida was due for reconstruction after years of salt water damage. Repair costs continued to increase with extensive cracking in the concrete and severe corrosion of the steel which caused spalling. The owner of the project was considering multiple options for a replacement wall. He wanted to ensure that the new structure would be able to withstand the salt water. The seawall needed to obtain a component that would create less cracks so the salt water would not come in contact with the concrete causing it to crack. The owner was confident that PREVent-C would give the structure a long life-cycle. After 3 months, there was no evidence of shrinkage cracks in the precast wall panels.

Logan International Airport, located in Boston, Massachusetts, decided to increase parking capacity in their West Garage that provided an additional 2,050 parking spaces. The majority of the project utilized precast concrete with topping slabs in order to expedite the construction timeline. Using these applications caused concern for shrinkage cracking and early deterioration due to the harsh environment the garage was located in. PREVent-C admixture was chosen to provide a dual mechanism shrinkage-mitigation technology creating nearly a crack-free project.

Around 40 years ago, the Rodgers Roads Bridge over I-95 was built in Wilmington, Delaware. In order to preserve the bridge's structural integrity a maintenance project was due for long term stability. With a variety of rehabilitation options, a mill-and-overlay repair was scheduled to take place. Overlays come with hardships such as a high occurrence of shrinkage cracks that lead to freeze-thaw deterioration requiring additional maintenance in the future. PREVent-C500 shrinkage-reducing/compensating admixture was implemented and reduced shrinkage cracking by 85-90% that will lead to a longer life cycle.

Listed on the U.S. National Register of Historic Places, the Cathedral Church of St. Paul in Boston Massachusetts went through vigorous interior renovations to create long term stability for its patrons. With extreme winters on the east coast, there needed to be radiant heating tubing in the new concrete floor which becomes a challenge. With high-paste content and the need to place joints in the concrete - shrinkage cracking and curling would take place and result in floor damages. PREVent-C Shrinkage Reducing/Compensating admixture was used during the project resulting in a crack-free 7,000 square foot slab.

After historic flooding to Fort Randall Dam, located in South Dakota, inspections made it clear there needed to be repairs toward the dam to promise long term stability. In order to reduce concrete shrinkage for such a large product, the owner chose to use PREVent-C admixture at a 5% dosage rate in their specialty concrete mix design. With 130,000 dowel anchors being required to be drilled into the concrete, PREVent-C would help the amount of strain it would create to the concrete.

Prevent Cracks with Volume Stable Concrete. The University of Utah’s basketball team needed to avoid concrete shrinkage and curling if they were going to be able to feature high quality wood flooring in their practice facility. With PREVent-C and 4 lbs/CY macro fibers, the entire 14,000-square-foot concrete slab was poured continuously with no joints. The floor flatness and levelness numbers were twice as stringent as required by specifications and no grinding was needed.

This Special Section appeared in May 2015 Rock Products and features comprehensive resources on Frac Sand geology, production, news, equipment and technology. Frac sand is a specialized sand that is added to fracking fluids that are injected into unconventional oil and gas wells during hydraulic fracturing. While the principal source for frac sand is the traditional glass sands of the Midwest that are primarily pure silica, the high silica content is but one of the necessary criteria. Among the additional specifications are requirements for high sphericity/roundness, a uniformly medium- to coarse-grain size, high crush resistance, low solubility, low turbidity, and good friability. Additional factors that influence the economics of frac sand mining are the deposit’s accessibility at or near the surface, areal extent and thickness, textural uniformity, nearness to trucking and rail transportation routes, and proximity to the active unconventional petroleum basins.
