The belt and pulley is driven by the motor, which make the jaw move up and down through eccentric shaft rotation. The angle between toggle plate and moving jaw increases when jaw moves up. Meanwhile, the movable jaw plate is closing to fixed plate to make material crushed in the chamber. The angle between toggle plate and moving jaw decreases when moving jaw moves down. Meanwhile, the movable jaw plate is away from fixed plate by rod, springs, and hydraulic system effect to discharge the material. With hydraulic system, automation is realized, and the above periodic motions repeat to achieve batch production.
