Bauxite, the main component is alumina, hydrated alumina containing impurities, is a kind of earthy minerals. White or off-white, brown or light red due to iron. Density 3.9 ~ 4g/cm3, hardness 1 ~ 3, opaque, crisp. Extremely hard to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. It is mainly used for aluminum smelting and refractories.
(1) Aluminum smelting industry. For defense, aviation, automotive, electrical appliances, chemicals, daily necessities etc.
(2) precision casting. Bauxite clinker is processed into fine powder and cast into molds. For the military, aerospace, communications, instrumentation, machinery and medical devices sector.
(3) For refractory products. High alumina bauxite clinker refractoriness up to 1780°C, strong chemical stability, good physical properties.
(4) Aluminosilicate refractory fiber. It has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical vibration resistance. For steel, non-ferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, national defense and other industries.
(5) Using magnesia and bauxite clinker as raw materials and adding suitable binders, the overall barrel lining for casting steel drums is very effective.
(6) Aluminium cement, abrasives, ceramic industry, and chemical industry can produce various compounds of aluminum.
Guilin hengda mining machinery Co., Ltd is a professional ultrafine mill manufacturer from China. For bauxite ultrafine mill, HGM series is a good choice, not only for its factory price, but also multiple layers of multiple grinding roller, grinding wheel bracket with a combination of structure, the drive spindle is s multi-angle diamond-shaped structure, crushing power strong, less maintenance, easy demolition, low cost, and the finished product does not turn back.
