Technical Field

[0001] The utility model belongs to the technical field of grinding equipment, and specifically relates to a titanium dioxide grinding device. Background Art

[0002] Titanium dioxide is an inorganic compound with the chemical formula TiO2. It is a white solid or powdered amphoteric oxide with a molecular weight of 79.866. It is non-toxic, has the best opacity, the best whiteness and brightness, and is considered to be the best white pigment in the world today. Titanium dioxide has strong adhesion, is not easy to undergo chemical changes, and is always snow-white. It is widely used in industries such as coatings, plastics, papermaking, printing inks, chemical fibers, rubber, and cosmetics. It has a high melting point and is also used to make refractory glass, glazes, enamels, clay, and high-temperature resistant experimental vessels. Titanium dioxide can be extracted from rutile by acid decomposition or obtained by decomposition of titanium tetrachloride. Titanium dioxide exists in three allotropic forms in nature: rutile, anatase, and brookite, in addition to several artificially synthesized crystal forms.
