IROCK Crushers offers a RDS-15 horizontal impact crushing plant. As the name suggests, the RDS — rapid deployment system — provides exceptional portability and rapid set-up time, according to the manufacturer.

The RDS-15 is a versatile, compact crushing and screening system that provides 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-hp Caterpillar C-9 ACERT Tier III engine, the unit can process up to 350 tons per hour (317.5 t). The entire plant is self-contained, with on-board power supplying full plant operation. For added convenience, 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.

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-in. (61 cm) return conveyor, which drops the material back into the crusher. This design enables 20 percent more production than other machines. The boosted efficiency equates to greater production in less time, lower labor costs, less fuel consumption and lower operation expenses. This feature is ideal for applications such as asphalt recycling, where contractors commonly need a consistent half-inch product, according to the manufacturer.

The machine features a 5- by 14-ft. (1.5 by 4.2 m), 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-in. by 14-ft. (101 cm by 4.2 m) vibrating grizzly feeder. The two-step, tapered grizzly removes fines and only allows materials that need to be sized into the crusher, reducing potential wear on the crusher and further boosting efficiency. While 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.

Performance and production are further enhanced by IROCK’s four-bar impactor design. The RDS-15 provides the ideal balance inside the crushing chamber to optimize production and ease uneven wear on the blow bars. 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 rock box uses a shelf system with AR-400 steel wear bar. An innovative 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, which provides enhanced durability over rubber liners used by other crusher manufacturers, according to the manufacturer.

To reduce cleaning and maintenance requirements, 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 ft. (9 m) away.

For ultimate convenience, portability and quick set-up, 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.

IROCK is known for its heavy-duty components, high-quality units and exceptional customer service. The company has convenient 24-hour online parts look up and ordering, fast delivery and live service support from 8 a.m. to 9 p.m. EST.
