In the embodiment shown in FIG. 1, a recess 130 is provided on the base 110, and the recess 130 is located at the lower part of the base 110. The receiving container 300 is provided in the recess 130 and below the grinding part 400 for receiving grinding. Good powder. A powder outlet channel 210 is also provided in the base 110. The powder outlet channel 210 communicates with the grinding part 400 and the container 300 to form a relatively closed powder flow cavity for accommodating the flow of powder. The powder in the grinding part 400 is ground. It directly enters into the receiving container 300 through the powder outlet channel 210, effectively preventing the powder from being scattered. The area through which the powder flows in the grinder 100 is made of anti-static material. When the powder is ground and flows, it is easy to generate static electricity due to the extrusion and friction between the powders. The powder with static electricity is easy to be absorbed by the grinder 100. On the inner wall, the area through which the powder of the grinder 100 flows is made of anti-static material, which can effectively reduce the powder sticking to the inner wall of the grinder 100 due to electrostatic adsorption, and is easy to clean.
