Input dynamic by motor, the pulley drives eccentric shaft to make the movable jaw move upwards and downwards with SPC belt. When the movable jaw moves forth toward the fixed jaw, materials in the crushing cavity will be squashed or chopped. And then the movable jaw travels back, the chopped or squashed materials which met the requirements will be discharged from the outlet. Since the motor keeps working, the Jaw Crusher Machine will crush and discharge periodically to achieve mass production.
