Top 25 Rollouts of 2012
Sandvik says its new Vibrocone crusher is the next generation of crushing technology, which changes the rules for crushing and opens the way for energy savings and new eco-efficient crushing alternatives. It is said to combine the best of conventional crushing and grinding principles to produce a finely crushed product, while enabling up to 30-percent energy savings in downstream processing. In existing crushing circuits with rod and/or ball milling stages, it can replace the rod mills or act as a pre-grinding unit for the ball mills. The technology is covered by several U.S. patents, as well as additional international patents.
Superior says its new conveyor belt scale is designed to produce precision measurements with two, independent load cells that display readings separately on the diagnostics screen. The scale is available in two models — WB and HD. The WB model, with an accuracy rating of 1.0 percent (+/-0.5 percent), features independent weigh-bridge brackets and accommodates multiple belt widths. The HD model, built with a continuous weigh bridge for increased accuracy and structural integrity, boasts an accuracy rating of 0.5 percent (+/-0.25 percent). Both models can handle up to 2,000 tons per hour of material. An optional speed sensor mounts to most conveyor frames and adjusts to applicable belt widths.
Telsmith, Inc., an Astec company
Telsmith launched its new T900 cone crusher, a mine-duty machine designed to deliver maximum uptime, productivity, safety, and ease of maintenance. Output capacity ranges from 550 to 2,100 metric tons per hour. With up to a 15-inch feed size, the 900-horsepower crusher is designed with eight cylinders, rather than 12, and is said to be rated with the largest-in-class clearing stroke and the highest-in-class crushing force. It is nitrogen-free and engineered with a patented release system that eliminates the need for maintenance-intensive hydraulic accumulators. A new, patent-pending anti-spin feature mounted on top of the machine prevents head spin, which helps to extend manganese life.
Terex’s TA400 Generation 9 articulated haul truck boasts a 444-horsepower Tier 4 Interim-compliant Scania DC13 engine with a maximum torque of 1,548 foot-pounds at 1,350 revolutions per minute and a fully automatic Allison transmission. Additional features include a maximum payload of 41.9 tons, a heaped capacity of 30.3 cubic yards, dual retarder systems, a transmission retarder and exhaust brake, permanent 6 x 6 all-wheel drive, and equalizing rear suspension. The electronic-assisted hood raise and fully tilting cab simplify access to major components and ground-level service points. The truck is equipped with computerized systems that communicate with each other through a CAN-bus system to ensure everything is running at peak efficiency. Terex Corp.; terex.com.
