filling level monitoring at the
material hopper minimises the pull effect even at constantly
high rotor speeds, thereby ensuring that the material bed is
maintained and guaranteeing uniform quality, low wear costs,
and low dust emissions under full or partial load.
The SBM V8 vertical impact crusher has around 7.5 tons and is
an easily relocatable unit in a steel structure with a
surrounding maintenance platform. Therefore, it was very
simple to integrate it into the existing installation in Saaldorf.
The crusher is fed by wheel loader via a pivoting conveyor belt;
the crushed material is transported to the double-deck screen
by oversize material return conveyor belt to the feed hopper;
and there are wide conveyor belts for the final grain sizes 5/8
mm chippings and 0/4 mm crushed stone fines.
It all adds up
After some 200 operating hours, Matthias Moosleitner is very
positive: ‘We were able to integrate the SBM V8 into our
crushing plant without any problems. It delivers consistently
high-quality products, both in terms of grain form and grain
size distribution, which is essential for the controlled addition
to our washed concrete sand.’ The production output is also
excellent: ‘With 60 to 70 t/h, it easily equals the sand output of
our washing plant, and its independent operation gives us
complete flexibility to process any oversize aggregates at
hand.’
Plant Manager Peter Gastberger also emphasises the
advantages of the SBMM vertical impact crusher: ‘With V8, we
can precisely adjust the properties of the crushed material 0/4
mm to the washed material. Currently we are working with
three pre-settings in the crusher control system taking into
account the usual variability in the washed sand.’ The SBM V8
crusher also excels in operation and maintenance: ‘Even under
full load, the crusher operates quietly, with low vibration and
virtually no dust thanks to the inlet control. Especially in direct
comparison with our cone crusher, wear is extremely low,
which minimises maintenance and significantly increases the
availability of the V8 due to the electric drive concept.’ Take
winter operation, for example: While the cone crusher, with its
some 300 l of gearbox respectively hydraulic oil, requires a
considerable lead time at low temperatures, the SBM crusher
V8 is ready for operation in no time at all thanks to its grease
lubrication and only 10 litres of hydraulic volume necessary for
the gap adjustment.
