Brown Fused Alumina is made of bauxite and coke (anthracite) as the main raw material, and is produced by high-temperature smelting in an electric arc furnace. Grinding tools made of it are suitable for grinding metals with high tensile resistance, such as various common steel materials. , malleable cast iron, hard bronze, etc., can also be made of advanced refractory materials.

Brown Fused Alumina by Barmac Crushing is processed through Barmac production line. It has the characteristics of high bulk density, high purity, dense texture, strong self-sharpening, good toughness, and extremely low magnetic material content. Sharp cutting, low heat generation rate, high grinding ratio, and less adhesion during use, the sintered abrasive tool has the characteristics of dark blue, no mesh cracks, and no rust spots after firing. After washing, the dust is reduced to Lowest, suitable for the manufacture of ceramics, resin high-consolidated abrasives and grinding, polishing, etc.

Brown Fused Alumina by Barmac Crushing Process: it is made of artificially selected brown corundum blocks and processed by means of rollers, ball mills, barmac, etc. The grain size is used by F8-F325. It is mainly used for polishing, grinding, industrial grinding, etc. The customer requires the processing of water washing, pickling and other methods to meet the different needs of customers.

Brown Fused Alumina by Barmac Crushing Specifications: After pre-furnace and special process re-treatment, reduce the residual carbon content of brown corundum so that the product does not powder, burst, toughness is the first choice for the abrasive abrasive industry, refractory industry raw material.

Brown Fused Alumina by Barmac Crushing Use: mainly used for ceramic abrasives, high-grade abrasives, organic abrasives, abrasive belts, coated abrasives and so on.

Brown Fused Alumina by Barmac Crushing Features: according to the residual carbon content is divided into: calcined corundum C ≤ 0.05%, low-carbon corundum C ≤ 0.10%, ordinary brown corundum C ≤ 0.15%. The common name is also known as corundum, which is a brown fused alumina produced by melting and reducing alumina, carbon, and iron scraps in an electric furnace.
