October
11, 2012, Oakwood Village, Ohio – IROCK,
a leading manufacturer of screening and crushing equipment, has introduced the RDS-20 Primary Crushing Plant. The RDS – rapid deployment system – has
been built to provide exceptional portability and rapid set-up time.

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, recyclable materials and base rock for oil fields.

The machine
features a 5’ by 16’ 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 per hour (TPH). The initial vibrating
feed opening is 52 inches by 17 feet, while the crusher feed opening is 56 by
32 inches. 

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. In addition, with on-board power supplying full plant
operation, the entire process is self-contained. The crusher is powered by a
440-horsepower Caterpillar C-13 ACERT Tier 3 engine, but can also be supplied
with a Tier 4 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 patented 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 exclusive ROCK BOX, an innovative 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, reducing
maintenance.

To reduce
cleaning and maintenance requirements, the RDS-20 features a standard dust suppression
system. Catwalks enable easier screen change-outs 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-feet away to
remove it from the dust and vibration of normal operating conditions.
