This equipment is developed by several experienced engineers through years of hard-work which absorbed advanced domestic and international techniques. Its a new rubber grinding machine, which originally creates double turn-plate grinding structure, with high strength alloy sword used to cut and grind rubber grain mechanically. The equipment has lots of advantages such as original design, smaller volume, little vibration, low noise, high powder rate and quality grinding. 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 the two turn-plates to let grains fitting to filter output from the outlet
