BFA/Brown Aluminum Oxide for Sandblasting
Product Description
Brown fused alumina is made of high-quality bauxite, anthracite and iron filings. It is cooled and smelted in a high temperature by more than 2000 degrees in an electric arc. It is crushed and shaped by a jaw crusher and a ball mill. After magnetic separation, the sieve is divided into various kinds. Its compact texture, high hardness, suitable for the manufacture of ceramics, grinding of high tensile metal and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture advanced refractory materials.
