[0030] Secondly, the plurality of stirring rods 119 are respectively fixedly connected to the rotating rod 120 and are located on the outside of the rotating rod 120.

The electromagnet 116 adsorbs the metal impurities in the attachment, and the brush 122 can facilitate stirring the raw materials between the multiple electromagnets 116, thereby preventing the raw materials from affecting the adsorption of the electromagnet 116 on the metal impurities. When the stirring is completed, the telescopic rod 112 is started to move the two semicircular plates 111 in a direction away from each other. The raw material passes through the gap between the two semicircular plates 111 and enters the pulverizer body 105 for pulverization. Finally, the support cover 114 is taken out, and then the connecting ring 113 is taken out, and the electromagnet 116 is powered off. All the metal impurities adsorbed on the electromagnet 116 fall off, and the impurity removal operation is completed. In this way, the technical problem that iron impurities may be entrained in the raw materials during the processing of the materials, and these metal impurities may damage the production equipment, affect the product quality, and even cause safety accidents if they are not removed in time, is solved.
