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.

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.
