abrasive grade bauxite supplier, calcined bauxite producer

Abrasive grade bauxite

Abrasive grade bauxite, the calcined bauxite for abrasive, the most important raw material of BFA(brown fused alumina). Abrasive grade calcined bauxite has an Al2O3 content of 80-88% and a maximum silica content of 5%. The ratio of iron to silica should not exceed 3:1. The titania content, important in controlling the crystal structure and the hardness of the alumina grain, must be in the range of 2-4%. When it comes to calcining, refractory grade bauxite is usually fired at temperatures in the range of 1400-1800°C and abrasive grade at 1100C. Sinocean abrasive bauxite owns excellent genes for kinds of abrasive materials, high content in Al2O3(87%), low Fe2O3(2.0%max), low SiO2(around 5.0%), TiO2(2.5%-4.0%), perfect chemical composition for abrasive.

 

Application  

Raw material for high alumina refractories;

Raw material for Fused brown corundum; 

Some of this calcined bauxite is used directly as a fairy cheap abrasive product, but by far the largest amount is used as feedstock for the manufacturer of brown fused alumina (BFA) used in refractories.
