Working principle of rock jaw crusher

The electrical motor transmits power to the eccentric shaft through v-belt and belt pulley. Then the exciting force generated by the eccentric shaft will make the movable jaw move upwards and downwards. This movement would trigger the toggle plate to push the movable jaw forwards and backwards. When the movable jaw moves forth towards 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 meet the requirement will be discharged from the outlet. Since the motor keeps working. The crusher will crush and discharge periodically to achieve mass production.
