The WJC-2844 Wheeled Jaw Crusher byIROCK Crushers processes hard rock, recycled concrete, slag, sand and gravel. The crusher was displayed at CONEXPO-CON/AGG in Las Vegas.

Powered by a 350-horsepower Caterpillar® C-9 ACERT Tier 3 engine, the WJC-2844 can produce up to 370 TPH. The unit’s hopper is significantly larger than competing units and provides a capacity of 10.5 cubic yards.

The WJC-2844 is equipped with a 48-inch by 36-foot discharge belt and features a fixed discharge height of 11 feet, which is the highest in the industry.  Further, the superior stockpiling capability enables users to pair the WJC-2844 with screening units, which commonly have feeding heights of up to 10 feet.

With the WJC-2844’s hydraulic adjusting chamber, operators can adjust crushing sizefrom a two-inch minimum closed side setting to a six-inch maximum side setting. This allows the unit to produce a top size ranging from two to six inches.

The machine includes a 24-inch-wide grizzly bypass conveyor with an adjustable flop gate, as well as a 40-inch by 14-foot feeder with a five-foot grizzly bar section. These features ensure that material, 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 constructed with heavy-duty components for durability and is also designed to allow for easy maintenance. Components of the crusher are open and easily accessible for ease of lubrication, part replacements 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-inch 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 hydraulic outriggers for off-loading and leveling the plant. The WJC-2844 can be set up torn down in less than an hour.
