22 • ROCK products • July 2018 A t an aggregates operation, conveyors, stackers and ancillary equipment are important cogs in the production process. Here are some of the latest developments to keep material moving. ASGCO ASGCO's line of Tru-Trainer tracking idlers now includes the Dual Return model to accommodate high speed and tonnage associated with aggressive mining operations. The tapered ends sense any potential belt alignment issues and initiate the tracking correc- tions to take place instantly, without the need for edge contact rollers. A seize-proof external central pivot mechanism was designed, eliminating the need for a single, large drum, and enabling a concentric and balanced rotation to be achieved. This propri- etary design also makes Dual Return an excellent choice for reversing belt applications. This integrated design also extends bearing life and is proven to with- stand the toughest mining applications worldwide. "With the effectiveness of our Tru- Trainer flat return, it was natural to develop a variation that could handle the intense demands of high speed and high tonnage operations. We designed the Dual Return for those exact specs and have seen tremendous results in virtually every application," said Vice President of New Business Jeff Jurasits."The urethane version incor- porates rollers that withstand even the most abrasive conditions while continuing to provide excellent grip." Available for 48- to 96-in. belt widths, the Dual Return can accommodate con- veyor belt speeds that exceed 800 fpm and/or greater than 1500 piw. Installa- tion can be performed at the location of existing idler attachment points and can be configured to both push down or pull up depending on the belt's operation. Eriez Electromagnets Incredibly powerful and rugged Eriez SE Series 7000 Suspended Electromag- nets remove damaging tramp metal from coal, limestone, sand, gravel, municipal waste, wood products, recy- cled materials, other ores and almost any nonferrous material conveyed in heavy burden depths on flat conveyors or chutes. Twenty-three magnet sizes, 69 standard models and hundreds of designs are available to suit specific application requirements. Approved by leading safety agencies, these air-cooled, dry-type electro- magnets require no coolant fluids and reduce power consumption by up to 50 percent. UL-Listed construction is offered on units for use in hazardous, dusty and gassy locations. Eriez manufactures both Manual Clean- ing (MC) and Self Cleaning (SC) models. All SE Series 7000 Suspended Electro- magnets are backed by Eriez' exclusive five-year coil warranty. SE Series 7000 Suspended Electro- magnets feature several new design elements such as state-of-the-art, adjustable oil expansion tanks that prevent condensation and protect against hot spots to extend coil life. An array of special options are also available, including upgraded coil design for elevations greater than 3,000 ft. above sea level, high fire point cool- ants, zero speed switches, dust covers, pulley guards and controls, permanent extensions and monitoring devices, force-cooled units for high temperature applications and more. Kolberg-Pioneer Inc., Kolberg-Pioneer Inc. (KPI), which goes to market with Johnson Crushers Inter - national Inc. and Astec Mobile Screens Inc., offers a 170-ft. SuperStacker, its latest model of telescoping stackers. The 170-ft. SuperStacker is a new addi- tion to the product line. SuperStackers minimize material segregation by stockpiling in layers. Tail end coun- terweights and its wide operating footprint provide safe and efficient stockpiling, while also maximizing stockpile capacity. The new SuperStacker also features an updated, more user-friendly Wizard Touch automation control system. "The improved Wizard Touch system is designed to prevent material segre- gation and degradation," said product manager Jodi Heirigs. "The refined system features an expanded selection of stockpile options and is capable of inputting multiple stockpile recipes for operation diversity." High-Tech Material Handling Recent Product Introductions and Improvements Give Aggregates Producers New Options to Move and Handle Material. By Mark S. Kuhar Conveying
