Further Details:

Fields of Application

Four Roll Crushers are used for primary and secondary crushing. They are particularly suitable for medium and fine grinding processes, demanding a narrow particle size distribution and a low dust content.

Feed Materials

Raw material and products, for example in the

• Fertilizer industry

• Power plant technology

• Chemical industry

Mode Of Operation

• The crushing rolls are individually or driven in pair by electrical motors, counter-rotating via V-belts.

• The material is fed into the primary crushing stage by conveyors while it is spread over the whole width of the roll. The favourable angle of entry, determined by the optimum arrangement of the primary crusher rolls and corresponding grooves guarantees efficient into the primary crushing stage, even in case of large feed lumps.

• The optimum material guiding and the careful adjusting of the roller diameter towards the roller speed of the secondary crushing stage guarantee a gentle crushing process with a minimum of wear and tear.

Special Features

• Gap width of the primary crushing stage may be adjusted independently of the secondary crushing stage and ensures an easy and optimum coordination between the crushing stages.

• Depending on the application, the primary crusher roll are equipped with either grooves or teeth.

• In case feed materials are used with a tendency to clog, the crushing chamber and the material guides are lined with rubber.

• The Four Roll Crusher integrates an overload protection in both crushing states, which allows foreign particles to pass without causing damage to the machine.

• In order to facilitate maintenance, the roller shafts are arranged in amply-dimensioned spherical roller bearings. The bearings housing are equipped with lubricated labyrinths to avoid dust and dirt penetration.

Versatility

• The uniform final grain size is affected by the gap between the rolls/comb plate in the individual crushing stages.

• In order to alter the gap and to compensate wear and tear, the primary and secondary crushing stages are equipped with an adjusting devices.

• Gap width adjustment of the secondary crushing stage is effected mechanically or hydraulically.

Advantages

• High and constant capacity

• Space-saving simultaneous integration of two crushing stages

• High availability

• Gap adjustment independent of primary and secondary crushing stage

• Easy replacement of wear and spare parts

• Wide range of application

• Gentle crushing

• Overload protection

Scope Of Application

• Feed Size: Up to approx. 20mm

• Product size: Up to approx. <1mm depending on the feed material and its size

• Capacity: Up to approx. 15 t/h

• Max. required power: Approx. 45kW

Accessories

• Automatic gap adjusting device for the individual crushing stages

• Automatic grease lubrication system
