Talc is a common silicate mineral that is very soft and has a slippery feel. It is the softest mineral known, with a hardness of 1 on the Mohs scale. Talc has excellent physical and chemical properties such as lubricity, anti-adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, softness, good gloss, and strong adsorption. Talc crystals The structure belongs to the monoclinic system, which is composed of magnesium and silicon in hot water solution and rocks. It is distributed in Liaoning, Shanxi, Shaanxi, Shandong, Jiangsu, Zhejiang, Jiangxi and other places, and has abundant reserves.

Talc becomes talc powder after processing, which is divided into: chemical grade talc powder, used in rubber, plastics, paint, and other chemical industries as a strengthening and modifying filler; ceramic grade talc powder, used in Manufacturing high-frequency porcelain, radio porcelain, various industrial ceramics, architectural ceramics, daily ceramics and ceramic glazes, etc.; cosmetic-grade talc powder is a high-quality filler in the cosmetics industry and has the function of blocking infrared rays, thus enhancing the sun protection and anti-aging properties of cosmetics. Infrared performance; pharmaceutical and food-grade talc, used as additives in the pharmaceutical and food industries; paper-making grade talc, used in various high- and low-grade paper-making industry products. The paper produced can achieve smooth and delicate paper, save raw materials, Improve the service life of the grease mesh; and brucite powder, used in the manufacture of electric porcelain, radio porcelain, various industrial ceramics, architectural ceramics, daily ceramics and ceramic glazes, etc. The finished products of talc powder are available in 200 mesh, 325 mesh, 500 mesh, 600 mesh, 800 mesh, 1250 mesh and other specifications.

The processing technology of talc powder is to select high-quality talc from the mined talc (the raw material of talc powder) and then directly crush it with a Raymond mill or other high-pressure mill, and use a woven bag (50kg, or 25kg woven bag) is the finished product after packaging. At present, due to the popularity of cosmetics and other industries, the application market of talc powder is gradually becoming wider and the demand is increasing. The mining and processing industry of talc resources has also begun to become popular. Since the processing of talc powder requires grinding equipment such as Raymond mills, the mining and processing of talc resources will inevitably drive the further development of the grinding mill equipment market.
