Irock’s rapid deployment system designed to process up to 350 tons per hour

Irock, Valley View, Ohio, offers a RDS-15 horizontal impact crushing plant. As the name suggests, the RDS—rapid deployment system—provides portability and rapid set-up time, according to the company. 

The RDS-15 is a compact crushing and screening system that is designed to provide increased efficiency and the precision to produce a uniform product. While it can process a variety of products, the RDS-15 is ideal for processing smaller materials such as reclaimed asphalt pavement (RAP). 

Powered by a 350-horsepower Caterpillar C-9 ACERT Tier 3 engine, the unit can process up to 350 tons per hour (tph). The entire plant is self-contained, with on-board power supplying full plant operation. The unit features three outlets for powering optional auxiliary conveyors to sort and stack processed materials. Further, a P.T. electronic hydraulic clutch reduces power loss and increases fuel efficiency, according to the company

The unit’s closed circuit design gives operators the option to recirculate material requiring further sizing. By closing the flop gate, the two decks can feed onto the 24- inch return conveyor, which drops the material back into the crusher. This design enables 20 percent more production than competitors’ machines, says Irock This feature is ideal for applications such as asphalt recycling, where contractors commonly need a consistent half-inch product.

The machine features a 5- by 14-foot, double-deck huck-bolted screen frame. By opening the flop gate, the machine can process, screen and separate up to three different sizes of materials, two sized and one crusher run. 

Within the full-length fabricated steel plate hopper, the unit features a heavy-duty, 40-inch by 14-foot vibrating grizzly feeder. The two-step, tapered grizzly removes fines and only allows materials that need to be sized into the crusherWhile operators have an option to add Irock’s Hydraset Hopper, the unit is compact and light enough to be transported without the removal of the hopper. The hydraset hopper is designed to hydraulically attach and remove the hopper/feeder unit in one piece, with just one person, so it does not require the use of any outside lifting device. 

Blow bars can be removed, flipped and re-installed for a second lifecycle. Adjustable aprons are used to control the size of the crushed material. 

Irock’s exclusive Rock Box uses a shelf system with AR-400 steel wear bar. An alternative to discharge chutes found on similar units, the Rock Box allows crushed material to build up and act as a wear liner, effectively reducing maintenance and cutting down on costly labor and wear parts. Irock incorporates specialized AR-400 steel plate liners for each material transfer point.

The RDS-15 features a standard dust suppression system. For further protection from dust and vibration of normal operating conditions, operators can remove the machine’s control panel for operation from up to 30 feet away.

The mobile crusher can be hooked up to a truck and hauled as one unit. In addition, catwalks enable easier screen changeouts and provide convenient access to crucial maintenance and cleaning points.
