Jaw crusher

Operating principle 

Jaw crushers operate according to the principle of pressure crushing. The crushing material is crushed in the wedge-shaped pit between the fixed crusher jaw and the crusher jaw articulated on an eccentric shaft. The material is crushed by the elliptic course of movement and transported downwards. This occurs until the material is smaller than the set crushing size.

MPEX offers a range of jaw crushers for different feed and grain sizes and performance capacity. The single toggle jaw crusher has openings up to 1060 x 870 mm in size. The maximum capacity is up to 500 t/h.

Cone crusher

Operating principle 

With these crushers the crushing is effected by pressure crushing in an opening and closing crushing gap between the bowl liner and mantle. The opening and closing are affected simultaneously on the opposite sides of the crushing chamber.

With the cone crusher the crusher axle is pressed into the main frame. The mantle support is mounted on an eccentric hydraulic drive. The gap between the mantle and bowl liner is opened continuously with the rotation of the hydraulic drive. The grain size to be produced is changed by lifting or lowering the bowl liner.

Impact crusher

Operating principle 

In comparison to pressure crushing, the principle used here is impact crushing. In this process, the crushed material is picked up by a fast moving rotor, greatly accelerated and smashed against an impact plate ("impact toggle"). From there, it falls back within range of the rotor. The crushed material is broken again and again until it can pass through the gap between the rotor and impact toggle.
