Plant Description
Job Report
HAZEMAG & EPR GmbH has erected a new primary crushing plant for the Abyek Cement
Company, one of the major cement producers in Iran. The concept was successfully achieved
by constructing a state of the art plant incorporating 2 apron conveyors and a prescreening unit
for the processing of the raw material components marl (60 %) and limestone (40%).
The marl is dumped into the main hopper, from where it is extracted by a rugged, 14-metre
long apron conveyor. The limestone is extracted from a smaller hopper by a second apron
conveyor at right-angles to the marl conveyor.
Due to the high percentage of fines present in the feed material, a HAZEMAG wobbler feeder
is installed upstream of the impactor to eliminate the < 70 mm fraction from the material flow;
in this manner, the material flow rate to the crusher is reduced and at the same time the abrasive,
wet fines kept away from the crusher. The wobbler feeder surface comprises a series
of rotating shafts spaced at defined intervals and onto which are welded triangular discs; the
shaft spacings allow the unwanted fines to pass through the resultant gaps. The wobbler feeder
is designed to handle some 2,400 t/h, with a maximum of about 600 t/h fine material being
expected to pass through.
Technical Data
HAZEMAG wobbler feeder
Thanks to the high percentage of fines removed from the material flow, the size of the impactor
could be reduced and a smaller model selected. Nevertheless, the HAZEMAG Impactor
Type AP-PMH 2525 with a capacity of 1,800 t/h is still the largest impact crusher in the Iranian
cement industry. In addition to the rugged GSK-type rotor, the impactor is characterised by its
HAZtronic hydraulic impact apron adjusting system, which secures the aprons in their pre-set
position. On overloading or on entry of non-crushables, the impact aprons retract in a controlled
manner, returning to their original settings as soon as the hazard has passed. The gap
settings can be altered at the touch of a button, either at the machine itself or from the control
desk. The hydraulic control system provides for ease of operation, an extremely high degree
of operational safety and a consistent product quality.
