IROCK RDS-20 primary crushing plant has a 5x16-foot, double-deck screen. It can crush, screen and separate up to three different sizes of materials, two sized and one crusher run, at a rate of up to 500 tons per hour. The initial vibrating feed opening is 52x17 feet, and the crusher feed opening is 56x32 inches. Closed-circuit design allows both decks of oversized material to return to the feeder for another pass through the crusher after the initial round of screening. The crusher is powered by a 440-horsepower Cat C-13 ACERT engine.

A heavy-duty, two-step tapered grizzly removes fines and allows only large materials into the crusher. Hydraulically adjustable aprons allow for ease of adjustment and better control over sizing, while three optional auxiliary conveyors sort and stack processed materials. The mobile crusher features IROCK’s exclusive ROCK BOX, which uses a shelf system with abrasion-resistant wear bars that allow crushed material to build up and act as a wear liner, effectively reducing maintenance.

To reduce cleaning and maintenance requirements, the RDS-20 features a standard dust suppression system. Catwalks enable screen changeouts and provide access to crucial maintenance and cleaning points. Operators can remove the machine’s control panel in order to operate the crusher from up to 30 feet away to avoid the dust and vibration of normal operating conditions.
