This set of laboratory and pilot scale of crushing and screening plant is crushing the Polysilicon. First the raw material will be feed to the top hopper by the vacuum transfer pump.

Under the hopper, there is a small feeder, which will feed the raw material to the double roller crusher which equipped with tungsten carbide roller. after the material is crushered by the tungsten carbide roller crusher, it will enter into the round vibrating screen for different size seperation.

The parts contact with material adopt the tungsten carbide or polyurethane material, which will for high pure crushing work.
