This equipment absorbed advanced domestic and international techniques on the structural design of rubber powder grinding. Its a new rubber grinding equipment developed by several experienced engineers, initiated a stand joggling construction of grind and axis, high strength alloy sword is used to grind gum grain mechanically. The equipment is featured for its tight construction, little vibration, high powder rate and quality grinding function. Work theory: The rubber grains are rationed into the grinding room (the clearance between the movable grinder turn-plate and the stable grinder turn-plate) through the non-level derailleur with motor. Volume of the rubber grains can be controlled by adjusting the interval between grinders turn-plate to let grains fitting to filter output from outlet.
