Brown Aluminum Oxide uses bauxite with great quality as the main raw material, and created by sloshed into a large melting furnace of electricity by high temperature. It's the mainly raw material of refractory series and abrasive material series. Processing equipments are: Damark machine, Ball crusher and Air swept mill. Brown Aluminum Oxide not only uses in coated abrasive products, grinding wheel, sand blast, cuts, but also uses in steel industry unshaped refractory and castable refractory. We have both abrasive F series (form F12 to F220) and abrasive W series (form F240 to F1500 or form W68 to W5). Refractory series: 0-1mm, 1-3mm, 3-5mm, 5-8mm, 200mesh, 320mesh.
