52 E&MJ; • JANUARY 2017 www.e-mj.com EQUIPMENT GALLERY Joy Global introduced its ex- panding line of Joy brand service products and consumables at MINExpo 2016 in Las Vegas. The JoyCut integrated sys- tems solution, for example, in- volves testing, analysis and ulti- mately, the specifi cation, design and manufacture of the right cutting system for each under- ground mining application. The JS Blocksaver Mark I bitholder system is designed for ease of sleeve removal. Joy Fluids program provides free sampling and analysis to help extend equipment life and lower maintenance costs. On the surface, P&H; Optima dipper model upgrades include the heavy-duty Snubrite and roller latch door, which eliminates adjustments between preventative maintenance and extends maintenance intervals. P&H; Delta Series Heavy Duty shov- el crawler shoes with an elongated roller path provide better shoe-roller contact and more durability. Joy ground engaging tools (GET) meet all shovel, mining application and production requirements. www.joyglobal.com Crusher Design Protects Users, Inspectors Superior Industries Inc. launched the Valor Vertical Shaft Impac- tor (VSI), an impact-style bulk material crusher engineered to gen- erate fi nes, eliminate unsound material and shape aggregate into a more cubic product, the company reported. Maximum operating rate is 800 tons per hour (t/h) (725 metric t/h), and maximum feed size is 8 inches (203 millimeters [mm]). The VSI is equipped with a cartridge style, right angle pinion gearbox, which allows for a safer deck-mounted motor arrangement and simplifi es access to the drive and its components. A hydraulically powered lid allows for safe and easy access to the crushing chamber. A combination of automatic and manual safety interlocks protects maintenance inspectors. An autogenous rotor design promotes rock on rock crushing, which extends the life of many internal parts. http://superior-ind.com Engineered Alloys Postle Industries increased its offerings to include a hardfacing wire for ex- treme abrasion applica- tions, a high-hardness al- loy for high stress grinding applications, a manganese steel surfacing wire for equipment restoration, and a matrix welding wire for tungsten carbide embedding. Both Postalloy 2826 and Postalloy 2828-FCO, hardfacing wire for use in extreme abrasion applications like bucket teeth, present wear characteristics similar to those of chromium carbide hard- facing products, the company reported. Postalloy 2836-SPL and Postalloy 218HD resist severe abrasion, including high-stress grinding, low-stress scratching and gouging abrasion. Applica- tions include grizzly bars, conveyor screws and slag ladles. For manganese steel equipment and parts restoration, Postle offers two alloys. Postalloy 2865-FCO and Postalloy 2850-FCO. www.postle.com Custom Screen Liners Offer Durability Cast urethane screen wear products by ASGCO, when compared to rubber, last longer; offer superior abrasion, cut and tear resis- tance; offer superior tolerance to greases, oils, oxygen and ozone; and can better withstand harsh outdoor environments, the com- pany reported. The company's urethane wear products are cast from ASGCO-thane, a polyurethane compound with a durometer of 80/85, along with steel backing plate for extra added support. ASGCO screen feed box liners are patterned for a direct replacement of the current liner confi guration, or, depending on the wear characteristics, change the layout for maximum wear life. Screen side wear lin- ers are boxed in with mild steel or hard plate to pre- vent premature edge wear or damage. Full custom options come standard. www.asgco.com Dual Action Pump Drains Drums in Minutes The two-way, air-powered Vortec VacSystem Drum Pump, with no moving parts and no shock hazard, can fi ll or discharge a 55-gallon Joy Announces New Services
