After pulverization, the feed raw materials will be in the activated dust collector 12, connecting pipe 22, pulverizing material pipe 17 and exhaust pipe. With the cooperation of 18, the pulverized feed raw materials are directly guided from the connecting pipe 22 to the pulverizing material pipe 17, and finally back to the drum screen 7. At this time, the drum screen 7 is used for docking and screening again. The bottom of the inner wall of the shell 19 is dropped, and then from the discharge port to the collecting screw conveyor 14, and finally from the discharge pipe 15 to the raw material bin, and then it is directed to the semi-circular receiving block 10 again after it does not meet the particle size. , and then pulverized with the pulverizer 16 again, and then returned to the drum screen 7 through the cooperation of the connecting pipe 22, the dust collector 12, the pulverizing material pipe 17 and the exhaust pipe 18, and so on. Separation and pulverization will be carried out continuously. When the feeding screw conveyor 13 does not feed, the feeding screw conveyor 13 can be stopped first, and then the drum rotating motor 9, the collecting screw conveyor 14, the pulverizer 16 and the dust collector are in turn. 12.
