IROCK has introduced the RDS-20 primary 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-20 is a highly portable, easy to operate mobile unit. It combines a closed circuit design, high-performance four-bar impactor and heavy-duty components for reliability, increased efficiency and the precision to produce a uniform, cubical product. It also is versatile enough for use across multiple industries and can process a variety of materials, including quarry rock, demolition debris, recycled concrete, recycled asphalt and base rock for oil fields.
The machine features a 5- by 16-ft. (1.5 by 4.8 m), double-deck screen. It has the ability to 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 (453.5 t) per hour (TPH). The initial vibrating feed opening is 52 in. by 17 ft. (132 cm by 5 m), while the crusher feed opening is 56 by 32 in. (142 by 81 cm).
The equipment’s 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. This allows for 20 percent greater production than other machines. In addition, with on-board power supplying full plant operation, the entire process is self-contained. The crusher is powered by a 440-hp Caterpillar C-13 ACERT Tier III engine. The RDS-20 also can be supplied with a Tier IV engine.
Performance and production are further enhanced by IROCK’s four-bar impactor design. The RDS-20 provides the ideal balance inside the crushing chamber to optimize production and ease uneven wear on the impact bars. 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 RDS-20 is available with IROCK’s Hydraset hopper. The Hydraset hopper is designed to 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. The system operates from an internal power pack, which allows the unit to be easily detached and placed on a trailer in a matter of minutes.
The mobile crusher features IROCK’s rock box, an alternative to discharge chutes found on similar units, which cuts down on costly labor and wear parts. The rock box 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. It also incorporates specialized AR-400 steel plate liners for each material transfer point, which provides enhanced durability over rubber liners used by other crusher manufacturers.
To reduce cleaning and maintenance requirements, the RDS-20 features a standard dust suppression system. Catwalks enable easier screen changeouts and provide convenient access to crucial maintenance and cleaning points. And operators can remove the machine’s control panel and operate the crusher from up to 30-ft. (9 m) away to remove it from the dust and vibration of normal operating conditions.
