Mobile Kleemann equipment for crushing iron ore
The Kimberley Metals Group (KMG) launched the “Ridges Iron Ore Project,” a new mine in the Kimberley region of
Western Australia, in 2011. Here the iron ore is extracted from a mountain ridge, taken by dump truck to a central
location and processed. The processing itself is handled by SJ Crushing as a subcontractor of KMG. “The major challenge
for us was going very quickly from submitting our bid to a stable production of 500 tons per hour,” says Neil Fitzpatrick,
Project Manager at SJ Crushing, describing the project requirements.
Mobile combination of four Kleemann machines
SJ Crushing found its solution with Kleemann. “The director and owner of SJ Crushing, Steve Crabbe, saw clearly that
he needed a decisive advantage in order to be awarded the contract. And he found that advantage in equipment from
Kleemann, with its robust design and its diesel-electric power concept,” continues Neil Fitzpatrick.
Because the initially anticipated project duration was very short, just four years, it quickly became clear that
the solution would have to be a mobile one. The equipment in the mine is also quickly movable in case of changing
conditions or requirements.
Starting sizes of up to 1000 mm edge length, end product 0-10 mm
The cut or blasted material is transferred to the MOBICAT MC 125 Z by wheel loader. The size of the material recovered
by the surface miners ranges from 0-200 mm, while the blasted material can have edges up to 1000 mm long. In addition,
the compressive strength of the material can be far above 300 MPa.
The mobile cone crushers break the material down to a final grain size of 0-10 mm, each of the three units generating
the end product. The material from the bottom and to some extent the middle deck of the triple-decker screen units is
passed on to the next machine in order to ensure the high hourly output rate of more than 600 tons per hour.

Wheel Saw for Pipeline Projects
Otrac Heavy Equipment, the dealer for Bobcat and Doosan
organised two separate demonstration events promote the Bobcat
WS32 wheel saw attachment.
Before an audience of specially invited guests at both events,
the wheel saw attachment was put through its paces, mounted
on a new Bobcat A770HF all wheel steer loader to show why the
wheel saw is ideal for carrying out the trenching work that will be
required on future gas pipeline installation projects in Egypt.
