First semi-mobile Impact Roll Crusher of
HAZEMAG in Austria
Customer: LEUBE GmbH Cement Plant, Austria
Impact Roll Crusher SB 1515 R with integrated roller screen
Plant Description
HAZEMAG & EPR GmbH supplied the first semi-mobile impact roll crusher plant in Austria. It was purchased
by “Zementwerk Leube GmbH”, one of the leading companies of the Austrian building materials
industry.
Besides the compact and simple semi-mobile design (which is rather unusual for a 600 – 800 t/h limestone
crushing plant) the integration of a feeder grate as a primary screen was the decisive reason for
the purchase of the impact roll crusher.
Even with high through put and the large feed size of up to 1.2 m the end product had to have a final
crush size of 0-250 mm with a minimal amount of fines production in the final product.
The plant utilizes a 15 m² feed hopper and is fed using front end loaders. Thanks to the unique technology
of the horizontal flow neither a bench edge, nor a loading ramp is required for the feeding in comparison
to conventional primary crushing plants. Therefore, the unit may be relocated easily and quickly.
It is simple to use a front end loader to reposition the plant in less than 30 minutes without any problems
or any special pad to set the unit on.
The material is conveyed from the feed hopper via a solid chain conveyor (KF 1200) to the crushing
chamber. The roller screen (RR 1,1x14x25), which is integrated in the chain conveyor, guarantees a primary
screening of up to 120 mm. The feed greater then 120 mm is crushed in the impact roll crusher to
a conveyor-sized dimension with a grain composition of k98 = 250mm. In doing so, the end product will

only contain up to 17% max. grain size range of 0-16 mm.
The roll of the crusher is fitted with 7 adjustable impact
elements 3 on one side and four on the same plane on
the other side. These impact elements crush the material
directly on the chain conveyor as it fed into and through
the crushing chamber. The crushed limestone is then fed
to the discharge belt of the crushing plant which transports
the material via a downstream mobile conveyor plant to the
secondary crushing plant.
In comparison to most other mobile plants of this performance
class, this plant is exclusively environment-friendly,
utilizing 100% electric line power. The compact design means
there is no powered tracks required, which means there
is no requirement for a diesel generator to operate the
necessary hydraulics to operate the powered tracks.
Within only 10 days the plant was assembled in the quarry
and the first test runs with and without material could
be carried out After the necessary fine adjustments the
customer’s target values with regard to throughput rate and
fine grain were achieved.
