The graphite powder is soft and black and gray; has greasy feeling and can contaminate paper. The hardness is 1-2, and the hardness can be increased to 3-5 along the vertical direction with the increase of impurities. The specific gravity is 1.9-2.3. Under the condition of isolating oxygen, the melting point of the mineral is more than 3000 ℃, and the mineral is one of the most temperature-resistant minerals. The graphite powder has stable chemical properties at normal temperature and is insoluble in water, dilute acid, dilute alkali and organic solvent; the material has high temperature resistance and electric conductivity, and can be used as a refractory material, a conductive material and a wear-resistant lubricating material.

However, when the graphite powder is poured out by opening the cover of the conventional graphite powder grinding device, the graphite powder is overflowed in a limited space due to the fact that the cover cannot be closed and sealed in time, so that the graphite powder is harmful to the bodies of operators working for a long time. In view of this, we propose a sealed graphite powder grinding device.
