Graphite powder is a widely used industrial material, which is obtained from high-purity graphite after crushing, grinding, and screening. The classification of graphite powder is mainly based on the particle size, ranging from 50 mesh to 30000 mesh. The larger the mesh, the finer the particle size, and the higher the price.
Request a quoteGraphite powder is soft, black gray; It is greasy and can pollute the paper. The hardness is 1 ~ 2. Along the vertical direction, the hardness can increase to 3 ~ 5 with the increase of impurities. The specific gravity is 1.9 ~ 2.3. The specific surface area is concentrated in the range of 1-20m2 / g. when isolated from oxygen, its melting point is above 3000 ℃, which is one of the most temperature-resistant minerals. It can conduct electricity and heat.
There is no pure graphite in nature, which often contains SiO2, Al2O3, FeO, Cao, P2O5, CuO, and other impurities. These impurities often appear in the form of quartz, pyrite, carbonate, and other minerals. In addition, there are gas parts such as water, asphalt, CO2, H2, CH4, and N2.
The raw graphite ore after blasting is sent to the Stonebreaker through the ore car for crushing, and then to the ball mill for flotation. The wet graphite material from flotation is sent to the ball mill for grinding and selection. The selected wet material is bagged and sent to the drenching dryer for drying, which becomes the drenching material. The drenching material is already a finished graphite product. The drenching materials are sent to the drying workshop for drying and bagging, that is, ordinary graphite powder. The average carbon content of the finished products is 90%.
Graphite powder has excellent physical and chemical properties, good temperature resistance, self-lubrication, thermal conductivity, conductivity, thermal shock resistance, corrosion resistance, and other properties. It is widely used in, electronic picture tube manufacturing, fire-resistant materials, conductive materials, wear-resistant lubricating materials, high-temperature metallurgical materials, the atomic energy industry and national defense industry, pencil lead, pigment, polishing agent, etc.
