Introduction :
Dolomite is a carbonate mineral, respectively iron dolomite and manganeRecycling Machine se dolomite. Its crystalline structure resembles calcite, often rhombohedral. When cold dilute hydrochloric acid will slowly bubble. Some dolomites glow orange under cathode rays. Dolomite is the main mineral composition of dolomite and dolomite limestone. It is mainly used as flux for basic refractory and iron smelting in blast furnace. Calcium magnesium phosphate fertilizer and magnesium sulfate; And the production of glass and ceramic ingredients.
Dolomite can be used as refractorWashing Equipment y inner layer, slag making agent, cement raw material, glass flux, kiln industry, fertilizer, building and decoration stone material, paint, insecticide and medicine of reformer used in steelmaking. Can be used in building materials, ceramics, glass and refractory materials, chemical and agricultural, environmental protection, energy conservation and other fields.
Dolomite series products of various qualities: dolomite ore, dolomite sand 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-80 mesh, 80-120 mesh, dolomite powder 10 mesh through, dolomite ultra-fine powder 140 mesh, 325 mesh,600 mesh, 1000 mesh, 1600 mesh.
Dolomite heating to 700 ~ 900 ºC is decomposed iCleaning Swab nto carbon dioxide and a mixture of calcium oxide and magnesium oxide, said caustic magnesium marble, easy to react with water. When the cloud of writing 1500 ºC calcination, magnesium oxide become periclase, a - CaO CaO into crystals, compact structure, strong water resistance and refractoriness is as high as 2300 ºC.
