Brown Corundum 60# /Brown fused alumina Manufacture in china AL2O3 94.5%
Brown Fused Alumina is fused in the electric-arc furnace under the high temperature of above 2250°C with high quality bauxite as raw material and matched by the carbon material and scrap iron .Then, it was crushed by autogenous mill, removed the iron through magnetic separation, screened to variety granularity.
