Dolomite is a carbonate mineral, including iron dolomite and manganese dolomite. Its crystal structure is like calcite, often in the form of rhombohedrons; bubbles will slowly appear when exposed to cold dilute hydrochloric acid; some dolomites emit orange-red light under cathode ray irradiation. Dolomite is the main mineral component of dolomite and dolomitic limestone.

Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy saving and other fields. It is mainly used as a flux for alkaline refractories and blast furnace ironmaking; production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; and ingredients for the production of glass and ceramics. It is also used as a flux in the glaze. Some ancient kilns in the north, such as Ding Kiln, often add dolomite to the glaze, and dolomite is also added to some glazes in Jingdezhen, which requires a dolomite mill. support.

Dolomite powder is pure white, insoluble in water, with a relative density of 2.5, stable chemical properties, and a slippery feel. As a plastic filler, dolomite powder can improve the hardness, fire resistance, acid and alkali resistance, electrical insulation and dimensional stability of the product. It is widely used in plastics, rubber, cables, paints, coatings, ceramics, EVA, and other industries.

Application of Dolomite:

• Used in rubber, it can increase the volume of the rubber, improve the process ability of the rubber, play a role of semi-reinforcement or reinforcement, and can adjust the hardness of the rubber.
• In plastics, it can increase the volume of the plastic, reduce the cost of the product, improve the dimensional stability of the plastic and the hardness and rigidity of the plastic, improve the heat resistance of the plastic, and improve the astigmatism of the plastic.
• Used for exterior wall insulation mortar, putty powder, ball factory lawn self-leveling mortar, epoxy floor, exterior wall latex paint, real stone paint, FRP sand pipe, plastic, rubber, paint, coating, etc.
• Dolomite is used in friction material as a stable friction coefficient. Dolomite can also improve process performance, the wear resistance of friction material, and reduce the cost because it is fairly cheaper when compared to other fillers.

It can be seen that the application market of dolomite has broad prospects. Dolomite powder processing is generally divided into dolomite coarse powder processing (0-3mm), fine powder processing (20 mesh-400 mesh), and dolomite ultrafine powder deep processing (400 mesh-1250 mesh) and micro powder processing (1250 mesh) -3250 mesh) four types, select the appropriate equipment according to different processing techniques.
