The crushing method of the PEV series jaw crusher is the curved extrusion type. During operation, the motor drives the pulley, which swings the movable jaw up and down through an eccentric shaft. When the movable jaw rises, the movable jaw plate approaches the fixed jaw plate, and at the same time, the material is subjected to multiple crushing processes such as compression, rubbing, and rolling; When the movable jaw descends, it leaves the fixed jaw plate under the action of the reset spring, and the crushed material is freely discharged from the discharge port under the action of gravity. With the continuous transmission of the electric motor, the crusher's jaw undergoes periodic crushing and discharging, achieving mass production.
