1. The motor drives the belt and pulley, and the eccentric shaft makes the moving jaw move up and down periodically.
2. When the moving jaw moves upward, the angle between the elbow plate and the moving jaw increases, which pushes the moving jaw plate close to the fixed jaw plate.
3. Materials are extruded, rubbed and ground repeatedly to be crushed.
4. When the moving jaw moves downward, the discharging opening becomes larger, and the finished materials are discharged under gravity.
