irc_magnum20_thumbSeptember 10, 2013, Valley View, Ohio – The new Magnum
crusher from IROCK is a high-performance four-bar impactor with heavy-duty
components built to improve reliability, as well as increased efficiency and
precision.

IROCK offers the Magnum in three sizes – the Magnum 15, Magnum
20 and Magnum 30, all of which are built to handle quarry rock, demolition
debris or recyclable material.

The Magnum 15, 20 and 30 are equipped with Cat ACERT Tier 3
engines and feature 350-, 440- and 550-horsepower respectively. The Magnum 15 is
capable of processing up to 350 TPH, the Magnum 20 up to 500 TPH and the Magnum
30 up to 650 TPH. Each unit includes three auxiliary outlets for the operation
of transfer or stacking conveyors. Additionally, each unit is equipped with a
P.T. Tech clutch, which decreases power loss and increases fuel efficiency.

Magnum crushers are portable, and operators can
enhance the ease of transport with IROCK’s optional patented Hydraset Hopper.
The Hydraset Hopper operates from an internal power pack, which allows the
hopper to be detached and placed on a trailer in a matter of minutes without a
lifting device. This is crucial with the Magnum 30, which cannot be transported
without the removal of the hopper because of weight limitations. After relocating,
the hydraulic outriggers make for fast and easy set-up.

A vibrating feeder with a heavy-duty, two-step tapered
grizzly removes fines and allows only large materials into the crusher. The
feed openings vary in size with each model, ranging from 40 by 32 inches to 56
by 43 inches.

Hydraulically adjustable aprons with three-stage crushing on
IROCK’s impactor crushers allow better control over sizing. The four-bar
impactor design offers maximum material reduction that minimizes wear and
enhances performance and production.

The mobile crusher features IROCK’s exclusive rock box, an
innovative alternative to discharge chutes found on similar units. 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. It also
incorporates specialized AR-400 steel plate liners for each material transfer
point, which provides better durability compared to rubber liners used by other
crusher manufacturers.

Finally, an optional in-line discharge belt reaches a
discharge height of 10 feet 11 inches for higher stockpiling and the ability to
pair Magnum crushers with screening units.
