The polysilicon is sprayed with water through the water nozzle 208 to cool it down. At the same time, the output shaft of the servo motor 206 drives the crushing shaft 203 to rotate. At this time, the polysilicon is crushed under the action of the first crushing teeth 204 and the second crushing teeth 205. The crushed polysilicon will fall into the inside of the drain frame 210.
