  • Crushing technology | Technologies | Kleemann

    Jaw crushers operate according to the principle of pressure crushing. The crushed 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 falls down due to gravity. This occurs until the material is smaller than the set crushing gap. The crushing energy acts
