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 supplier from China. For Bauxite raymond mill, HD series is a good choice, it breakthrough the bottleneck of the grinding mill, the production is 20-30% higher than traditional raymond mill, The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power. With the original roller assembly, the oiling time increased 6 – 15 times, achieve the application of oil once, use for 30-45 days.Higher Accuracy powder Classify, without coarseness missing, e accuracy is 80-600 meshes. The classify efficiency reached 99%. HD series has the advantages of high production, high qualification rate Low noise and vibration in grinding of the 325-400 meshes.
HD series high efficiency raymond mill specifications:
Max feeding size: ≤35mm
Main motor power：45-315KW
Final product size: 80-400 mesh
Applications : For non-metallic minerals with a Moh’s hardness of 6 or less and moisture content of 6% or less, it has a high productivity and high grinding power, such as talc, calcite, calcium carbonate, dolomite, , Kaolin, clay, graphite, zircon sand, bentonite and other non-metallic minerals.
