The crushing chamber consists of a fixed jaw and a jaw that moves in an elliptical motion with a conical gap between them. The material is forced against the fixed jaw by the moving jaw, causing it to be crushed and fall down through the crushing gap. During the crushing process, very high forces act on the material at low speed.
