The feeding chamber 19 has a conical inner cavity, and the feed port 18 is connected to the top of the cone. The feeding rotor 8 rotates at high speed to draw the material into the feeding chamber 19. The high-speed rotation of the feeding rotor 8 drives the material to be sheared and crushed in the feeding chamber 19, and then ground by the grinding rotor 9. The powder that meets the required mesh size enters the discharging chamber 20 through the filter screen 10 and is discharged from the discharge port 11 by the discharging rotor 3.
