When the action moving jaw and movable jaw plate in the eccentric shaft, spring back, the previously been crushed or split pieces of material from the lower jaw of the discharge port discharge. With the motor continuously rotating motor broken jaw for periodic crushing and waste material, to achieve mass production.
