www.rockproducts.com ROCK products • July 2015 • 33 EQUIPMENT & TECHNOLOGY CRUSHING & BREAKING I ROCK Crushers introduced the WJC- 2844 wheeled jaw crusher. Recom- mended for use as a primary crusher, the WJC-2844 adds to IROCK's already diverse product line. The WJC-2844 is capable of processing hard rock, recy- cled concrete, sand and gravel, and slag. Powered by a 350-hp Caterpillar C-9 ACERT Tier 3 engine, the WJC-2844 can produce up to 370 tph. Providing a capacity of 10.5 cu. yd., the hopper on the unit was designed significantly larger than competing units. The WJC-2844 is equipped with a 48- in. x 36-ft. discharge belt and features a fixed discharge height of 11 ft., which is the highest stockpiling height in the in- dustry, according to the company. Fur- ther, the superior stockpiling capabili- ty enables users to pair the WJC-2844 with screening units, which commonly have feeding heights of up to 10 ft. A hydraulic adjusting chamber allows operators to adjust crushing size from a 2-in. minimum closed side setting to a 6-in. maximum side setting. The machine includes a 24-in.-wide grizzly bypass conveyor with an ad- justable flop gate, as well as a 40-in. x 14-ft. feeder with a 5-ft. grizzly bar sec- tion. These features ensure that mate- rial, depending on its size, is properly classified and directed to either the side discharge conveyor or the crusher discharge conveyor. In addition, the WJC-2844 is construct- ed with heavy-duty components for durability and is also designed to allow for easy maintenance. Components of the crusher are open and easily acces- sible for ease of lubrication, part re- placements or other maintenance. For added convenience, standard catwalks and ladders provide easy access. For easy transport of the entire plant, the wheeled crusher features radial tires mounted under a 24-in. beam chassis. The unit features quad-axle rear ride suspension and includes a fifth wheel pin. For quick setup, the WJC-2844 is equipped with four hy- draulic outriggers for off-loading and leveling the plant. It can be set up or torn down in less than an hour. IROCK Crushers, www.irockcrushers.com T he Masaba Portable C125 Plant allows for efficient trans- portation. This unit features a grizzly hopper module that hydraulically lifts off the wide flange beam chassis for travel. Hydraulic legs allow this hopper module to be transported on a low boy without the use of a crane. The hopper mod- ule is built from 3/4-in. AR steel and comes complete with hydraulic folding wings to maximize feed capacity. This unit can be customized to fit specific operational needs.
