se：to produce fine rubber powder of 40-100 meshes.
Construction and Principle：The unit consist of three main grinder，whirlwind collecting mechanism，water cooling mechanism and a complete set of electric equipment。The main grinder consists of the frame，main motor，stepless variable speed motor，feeding mechanism，regulation mechanism and a pair of grinding dicss(a moving grinding disc and a static grinding disc)。
The basic principle is as follows：The material is ground under the function of the shearing and grinding activated by the rotation of the moving grinding disc。The water and the air effectively control the temperature during the grind process,thus ensuring the quality of the ground material。The stepless variable speed motor is used for the feeding mechanism。The feeding speed can be adjusted for the different material,thus achieving the most ideal capacity and quality。The end powder is sucked out under the whirlwind collecting mechanism.During the whole process，there is no powder flying。
Features：small size，low noise，high capacity，low power,easy to handle，convenience for operation and no pollution。
