3.Description
Bauxite is earthy mineral which consists mainly of Al2O3 , a kind of hydrated alumina containing impurities. According to the usage, It can be divided into the levels of Metallurgy, chemical industry, grinding, cement, and refractory. Clinker is pale yellow and dark grey. It is mainly used for high aluminum refractory material, and also can be used to make the fused corundum. Our materials of calcined bauxite is mainly D-K Style Bauxite Ore.

5.Material
Our material is from Yangquan, Shanxi,China. Yangguan bauxite ore have the best plasticity and adhesion. It can improve their product life.
Furnace and fuel,We have 6 shaft furnaces and use the gas for fuel. It can increase the temperature to fully burn, improve the bulk density and reduce impurities. In addition, using the gas can reduce the energy consumption, less CO2 emission for improvement of the work environment.
Annual supply, 60,000mt of calcined bauxite per year

Application,
1, Aluminium metallurgy
2, Precision casting/Investment casting,
bauxite grog fines can be made into mold for precision casting.
3, Refractory, High alumina bauxite's refractoryiness can reach 1780oC. It is charactered by good chemical stability and mechanical performance.
4, Aluminium silicate refractory fiber, The high alumina bauxite grog can melt under 2000oC to 2200oC in the electric arc furnace.After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket, cloth, plate and so on
5, Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.
6,Producing bauxite cement
7,Abrasives
8, Ceramics industry
9, Chemistry industry for all kinds of aluminium compound.
