Product description
Brown fused alumina powder for refractory
Brown fused alumina Refractory is made of high-quality bauxite, anthracite and iron filings. It is cooled and smelted at 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.

Brown fused alumina 95% Brown fused alumina 94%
What the different of the two kinds of BFA refractory section and:
1.Purity:
Brown fused alumina refractory sand made by Barmac milling machine get an Al2O3 purity min 95%.
Brown fused alumina refractory sand made by ball milling machine get an Al2O3 purity min 94%.
2.Shape:
Brown fused alumina refractory sand made by Barmac milling machine was reshaped and get a rounder sand shape.
Brown fused alumina refractory sand made by ball milling machine is with sharper sand shape.
