At this time, the material is ground by the cooperation of the conical grinding roller 132 and the grinding disc 131. After the material is ground into powder, the suction of the powder selecting fan blade 112 will suck the dust upwards and flow into the discharge pipe 111 for discharge. When the powder selecting fan blade 112 rotates, the arc-shaped protrusion 113 will rotate, and when the arc-shaped protrusion 113 contacts the connecting ball 43, the connecting ball 43 will be pushed upwards. Then, the movable rod 41 drives the limiting ring 44 to move upwards and stretch the spring 45, and the impact ball 42 collides with the discharge pipe 111.
