Clirik Dolomite Ultra Fine Grinding Mill 2019-11-22

Clirik ultra fine grinding mill can be used in 300 mesh to 2500 mesh dolomite powder making and the powder also can be used in many industries. As a solvent and refractory material, it is widely used in the metallurgical industry; it is used in the chemical industry to make calcium magnesium phosphate fertilizer, granular fertilizer and magnesium sulfate; in the building materials industry, it is also a glass and ceramic ingredient and building stone; sometimes used Refined magnesium metal.

1. Dolomite refractory materials:

Dolomite has been used as a refractory material for more than 100 years. At present, dolomitic refractories have a large number of applications in the industry. Metallurgical dolomite sand and tar dolomite bricks containing free calcium oxide and stable dolomite bricks without free calcium oxide are the main products, which are widely used in refining. The lining of steel flat furnace, electric furnace, converter, non-ferrous metal smelting furnace and cement firing kiln and the refractory material at the furnace wall, the product has strong resistance to erosion of alkaline slag, and it can greatly extend the life of the furnace.

2. Dolomite is used in the metallurgical industry:

Dolomite is divided into refractory products and used in the furnace lining of metallurgical industry furnaces. It is also widely used as blast furnace smelting flux and sintering pellets. Adding a certain amount of dolomite during ironmaking can dilute the slag and reduce the melting point of the slag, thereby improving the smelting conditions and the quality of pig iron. In the process of steelmaking slag, adding a certain amount of limestone to replace part of the quicklime can suppress the magnesium oxide in the lining material. Dissolved in the slag to protect the lining.

3. Dolomite is used in the construction industry:

Bonding materials such as gas-hard dolomite, hydraulic dolomite and magnesium cement can be produced by light burning from marble. The magnesium-containing cement prepared by light burning from marble ore with magnesium chloride solution or magnesium sulfate solution has high adhesion and plasticity, short solidification time, strong binding force with organic substances, hard and beautiful color after hardening. The building materials have good heat insulation, sound insulation and wear resistance. The hardness and elasticity are also stronger than the general cement. The light burned dolomite is mixed with the organic aggregate to make the products such as particle board, wood chip, artificial marble and heat insulation material. It has been widely used in the construction industry. Dolomite is processed into white cloud ash by appropriate calcination. It has whiteness, strong adhesion, coagulation force and good fire and heat insulation properties. It is suitable for interior and exterior wall coatings. Dolomite can also be used as an ingredient in cement, glass and ceramics in the building materials industry. The addition of dolomite (40%) to the cement can accelerate the hydration speed of the cement; dolomite can increase the strength and luster of the glass; the ceramics with dolomite as the ingredient are called "dolomite pottery".
