SBM cone crusher manufacturers for you to explain dolomite with major applications cone crusher equipment after processing Crusher Manufacturers In Europe, dolomite cone crusher is widely used inseparable:
use in the metallurgical industry, metallurgical industry
dolomite in the main used as a flux, refractories, refining magnesium and magnesium compounds. Used as a flux, dolomite flux as iron and steel, can play a role in acidic slag, increase the alkalinity of slag, slag FeO reduce the activity, in order to reduce erosion of the lining of the slag. Light-burned dolomite is mainly used in steel-making, to improve slag fluidity, as slagging agent, not only to extend the life of the converter to improve the fluidity of the slag can be improved desulfurization, dephosphorization reaction, the cone crusher can be save a lot of fluorite. The current production of 1t of steel consumes 170kg dolomite. Join dolomite can be diluted when the blast furnace slag, slag lower melting point, lower fuel consumption and improve the quality of pig iron.
use in the building materials industry
after appropriate calcined dolomite, processed into gray clouds, it has white, strong adhesion, coagulation force and good fire resistance, thermal insulation properties, suitable for making interior and exterior paint. After calcined dolomite, magnesium chloride can be used as cement and cement magnesium sulfide, because with good compressive strength, flexural strength Jaw Crusher Machine In Zimbabwe, and can fire anti-moth excellent performance, after adding other fillers can play a very good The waterproof, it can be used for flooring, and low prices. Dolomite powder can be used as a road paved fracture treatment and sintering materials and cement residue. 40% dolomite cement added to accelerate the rate of hydration of cement. Dolomite can also be directly used as building materials. In addition, the construction industry used to do dolomite cement and glass, ceramic ingredients, it can increase glass strength and luster. It is reported that foreign countries have been using the semi-calcined dolomite formed after the inorganic magnesium silicate brick and foam.
use in agriculture
dolomite can be used as soil acidity neutralizers, acid can neutralize a result of the use of urea fertilizer and caused crop production. Dolomite is mainly used for neutralizing acidic soil, use it to compensate for the crop loss caused by absorption of calcium and magnesium in the soil, crop production can be administered dolomite 15-40%. Calcitic dolomite by agricultural lime treated can be used as pesticides for pest prevention and cure.
dolomite is mainly used for the production of chemical industry magnesium sulfate, light magnesium and other chemicals. 30% sulfuric acid and dolomite by mixing, reaction, separation and concentration, temperature conditions under precipitated calcium sulfate, magnesium sulfate solution obtained cooling and crystallization, that was magnesium sulfate (MgSO47H2O).
extracted from seawater Mg (OH) 2, when used as a precipitating agent calcined dolomite, and also recovered dolomite MgO, increased production. Calcined dolomite, digest, carbonation, filtration separation, heavy magnesium water, then heating decomposition filtration, light magnesium [xMgCO3yMg (OH) 2zH2O]. Cone crusher equipment lightweight magnesium carbonate decomposition in light magnesium oxide, which can be fired with high purity magnesia.
dolomite used as a filler can be used for rubber, paper fillers. Quality dolomite powder can be used for expensive titanium dioxide filler substitute is used as a filler of some products can improve product color, resistance to weathering capabilities, improve the mechanical stability, reducing shrinkage and internal tension, reduce water and oil absorption capacity and expansion of the cracks, such products including adhesives, sealants, plastics, paints, detergents and cosmetics.
