C series jaw crusher is mainly composed of a frame part, eccentric shaft rotating part, crushing cavity working part, safety device, discharge port adjustment device, etc. The crushing method of the C series jaw crusher is curved extrusion type. The motor drives the belt and pulley, and the movable jaw swings up and down through the eccentric shaft. When the movable jaw pushes the movable jaw to move toward the fixed jaw, the material is crushed or chopped. When the movable jaw and the movable jaw plate retreat under the action of the eccentric shaft and the spring, the previously crushed or chopped materials are discharged from the lower discharge port of the jaw plate. With the continuous rotation of the motor, the crusher jaws periodically crush and discharge materials to achieve mass production.
