Technology for making magnesium oxide light calcium carbonate from dolomite

Posted: 2019 12 26 Source: Kefid Shanghai Machinery Views: 327

Dolomite is calcined at a certain temperature, passes professional milling equipment, and is then digested, decontaminated, kiln gas purification and compression, carbonization, filtration, pyrolysis, separation, drying, calcination, and classified packaging to obtain industrial magnesium oxide, high-purity magnesia, active magnesia and other magnesia products. The waste residue generated in the filtering process is magnesium-containing calcium carbonate. After further processing, ultra-fine lightweight calcium carbonate products can be prepared. The intermediate product prepared in the production process is basic magnesium carbonate, and a light magnesium carbonate product can be prepared by drying, pulverizing, and packaging.

The processing and processing of magnesium oxide with Kefid Mill is mainly used in the manufacture of ceramics, enamels, refractory materials; as a filler in the manufacture of polishing agents, adhesives, paints; in artificial fibers, rubber (neoprene, fluorine rubber ) is used as an accelerator and catalyst; it is also widely used in the fields of medicine and food; in the building materials industry, magnesium oxide can be used to produce special cements containing magnesium and insulation boards; in the chemical industry, it is used to produce metal magnesium and magnesium chemicals; In the field of environmental protection, it is used for water treatment and flue gas desulfurization; in addition, it is also widely used in glass, dye, cable, metallurgy, electronics, electrical, insulating materials, petroleum additives, casting, phenolic plastics and other industries.

Magnesium carbonate can be used as an excellent filler and reinforcing agent for rubber products. It can also be used for thermal insulation and high temperature resistant fire insulation materials. Light magnesium carbonate is an excellent insulation material used in shipbuilding and boiler manufacturing sectors. In addition, it is also widely used in glass products, magnesium salts, pigments, paints, fire-resistant materials, printing inks, ceramics, cosmetics, toothpaste and other daily chemicals, as well as medicine and food.
