Brown Fused Alumina For Abrasive

Cooled and smelted under an electric arc at a high temperature above 2000 degrees, brown fused alumina for abrasive is composed of quality bauxite, anthracite and iron filings. Normally, the brown fused alumina for abrasive will be crushed into shape by jaw crusher and ball mill. After magnetic separation, it will be screened into many kinds. HAOYUN brown fused alumina for abrasive has a dense texture and it has a high hardness of 9 Mohs.
