AGG1 Show Issue THUR FEB 18 9 30 11 00 A M Dust control in crushed stone sand and gravel operations Rick Felde Dust Control Technology Dust control is an important part of stone and gravel processing transfer and storage operations The presence of dust can pose a health risk to workers be a nuisance to neighbors increase equipment maintenance costs and impair visibility Dry collection and wet suppression are commonly used in the aggregates industry This seminar focuses on the applications and costs associated with each technology and discusses the most effective control strategies for optimum performance Safety and health management systems Steve Boydston DNV Business Assurance Increasingly companies are looking to systematize their approaches to safety and doing so in as strategic a manner as possible For this reason development of a safety and health management system is seen by many industry leaders as vital This presentation discusses various approaches such as ANSI Z 10 and instructs on such key elements of a system as training accountability measurement and continuous process improvement The presentation discusses potential obstacles to creation and implementation of programs and ways to avoid those challenges Washing Texas style Brian Bailey Vulcan Materials Co Blend new and old technology to build todays wash plant By combining new and old technology Vulcan has designed and built their sand systems including tanks screw washers dewatering screens separators and fines recovery systems Where they fit in the system will be shown by actual field case studies using Vulcans Texas operations as an example Maximizing plant productivity by benchmarking and evaluating performance Bob Bartok Paschal Associate Sales George Fox Luck Stone Phillip Gosnell Rogers Group and Dan Humpal Martin Marietta Materials The presentation demonstrates the advantages gained by establishing plant performance benchmarks and tracking actual changes or simulating proposed changes to determine the impact on productivity The theory and practical application will be demonstrated using real life before and after operating results Elements include establishing benchmarks in new and existing plants reviewing plant data and performance through field samples and evaluating process equipment performance Equipment from AGG1 exhibitors Superior Industries The company introduces a new set of transfer conveyors designed for a new level of efficiency during loading and unloading In less than 10 minutes the three unit conveyor system can be converted from a transport to operational mode The idea behind the newly released Slide Pac conveyors is first to reduce freight costs transporting up to 240 ft of conveyors in one load Secondly after transportation the system is designed with a roll style slide off system for safe and speedy unloading of the top two conveyors from the bottom trailer unit From start to finish the entire unloading process takes minutes to complete The three in one conveyor system is available in lengths of 60 ft and 80 ft for up to Rail transportation of aggregates Robert Pickel National Steel Car Changes in aggregate production locations and consuming markets have dramatically increased the role of rail transportation of aggregates Higher oil prices have made rail desirable over truck hauling This phenomenon has been complemented by an emerging market of increased demand of aggregates for scrubber stone in coal fired electric power plants These events have had a dramatic impact on the way aggregates are handled by the railroads the equipment railcars that hauls the product and the handling of such traffic at origin and destination by producers and consignees Tier III engines and beyond Caterpillar John Deere and DA Lubricant Co This topic explores Tier III compliant engines with special emphasis on lubricants and impact performance of low sulfur fuels and then considers the next step Tier IV engines The intent of this session is to prepare producers for the cost and effort that will be needed to meet these new engine requirements and to provide some guidance on steps to take prior to enactment of the regulations 240 ft of conveyor length in one load The trailer unit can be raised to a 125 ft discharge height is equipped with air brakes a fifth wheel hitch and travel lights The company manufactures its 80 ft units with a tandem axle design www superior ind com Booth 2317 Linatex Corp of America Featuring abrasion resistant compounds easy serviceability and an interchangeable design the Linatex G4 pump range includes rubber and hard metal pumps The rubber pump is designed for use in abrasive slurry and chemical applications while the hard metal pump is engineered for coarse particle size and high head applications Each features hydraulic designs which reduce internal turbulence and minimize power draw for greater efficiency and each offers reduced downtime via easy access to all internal parts and components Plus all wear components are manufactured from natural Linatex premium rubber www linatex com Booth 2127 24 PIT QUARRY February 2010 www pitandquarry com
