Structure features:
1 Provide the spring protection device. Higher production capacity and better quality;
2 The safety device greatly reduces stop time.
3 The machine body is cast steel structure. The strengthening rib is installed at the heavy load position.
4 There is the adjuster that can quickly adjust the discharging size.
5 There is whole lubrication system, which will automatically close when the oil temperature is too high or the oil flows too slowly.
6 The good sealing performance of inner structure can effectively stop the dust and other small grains infracting the equipment.

Operational principle:
While the crusher is working, the rotor rotates with high speed under the driving of the motor. The materials getting in from inlet knock to the board hammer on the rotor; and then the materials are crushed after being assaulted by the board hammer. The crushed materials are counterattacked back to the liner for another crushing, finally discharged from the outlet. Adjusting the gap between the counter frame and rotor frame can change the grain size and shape of the materials.
