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. Our specification is as follows,
AL2O3 85%min
Fe2O3 2.0%max
SiO2 9%max
TiO2 4%max
CaO+MgO 0.5%max
R2O 0.3%max
Moisture Absorption 3% max
Bulk Density 3.0g/cm3 min
Size,200mesh,325mesh,100mesh,0-1mm,1-3mm,3-5mm and 5-7mm
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.
