1. Structure and Working Principle. Jaw Crusher: Jaw crushers have a fixed jaw plate and a movable jaw plate. The movable jaw plate moves back and forth against the fixed jaw plate, crushing the material by compressing it between the two plates. Impact Crusher: Impact crushers consist of a rotor with hammers or blow bars that spin at high speed.
