Crusher Series The Working Principle

Crusher Series The Working Principle

Jaw crushers; The working principle

Jaw crushers work according to the principle of pressure reduction. The crushing of the crushed material takes place in the wedge-shaped shaft between the fixed and the eccentric shaft moving crushing jaw. Due to the elliptical movement process, the crushed material is crushed and transported downwards. This happens until the material is smaller than the set crushing gap.

The jaw crushers of series

Hawkplant offers jaw crushers in various sizes and performance levels. The single-stage jaw crushers of the HWK series have inlet openings of up to 1600 x 2100 mm in size. The maximum capacity is up to 1500 t / h.

Cone Crusher; The Working Principle

In these crushers crushing takes place in a circumferentially opening and closing crushing gap between crushing shell and crushing cone by pressure crushing. The opening and closing takes place simultaneously on the opposite sides of the crushing chamber.

With the cone crusher, the crusher shaft is pressed into the subframe. The crushing cone carrier is displaced on an eccentric drive unit. Due to the rotation of the drive unit, the gap between crushing cone and crushing shell opens circumferentially. The size of the grain to be produced is changed by raising or lowering the crushing coat.

Impact Crusher; The Working Principle

In contrast to pressure reduction, the principle of impact crushing is used here. The material to be crushed is picked up by a high-speed rotor, accelerated sharply and thrown onto a fixed baffle ("impact swing"). From there it falls back into the circle of the rotor. Thus, the crushed material is further and further broken until it can pass the gap between the rotor and impact swing.

The Impact Crushers Of The Series

The impact crushers of the hwk series are so-called secondary impact crushers, so they are mainly used from the second crushing stage. They are suitable for medium-hard to hard rocks and gravel for feed sizes up to max. 250 mm. From pre-shredded material mineral mixtures and precious chips can be produced here. But even as primary crusher for river gravel SNH impact crushers achieve very good results.
