Brown aluminum oxide is made by high quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200C, and made into different grain sizes through crystal, choosing, crashing, magnetic, separating, screening, washing etc. It is characterized by its high hardness, good toughness and sharp shape in particles. Brown Fused Alumina(BFA) is made from Calcined Bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting and as polishing Media. Refractory grade BFA is used as a raw material in the manufacture of high Alumina refractory. It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.

Corundum with high quality bauxite as raw material, anthracite, iron Xiao, adopted in the arc smelting. Furnace 2200 above high temperature purification, impurity removal, crystallization, sorting, crushing, magnetic separation, screening and other processing means made of various particle size products. Its dense texture, high hardness, spherical particles, suitable for the manufacture of ceramics, resin high consolidation abrasive and grinding, polishing, sand blasting, precision casting, but also can be used to manufacture advanced refractory materials. Brown fused alumina with high purity, good crystallization, strong liquidity, low linear expansion coefficient, corrosion resistance. The practice of dozens of refractory production enterprises verified that the product has the characteristics of non-detonating, non-chalking and not cracking in the application process. Product size according to international standards and national standards of production, according to user requirements granularity of processing. General size number F4 ~ F320, its chemical composition depending on the size of different sizes. Corundum with high purity, dense texture, bulk density, self-sharpening, good toughness, low magnetic matter content features, with its abrasive grinding sharp, low heat rate, high grinding ratio, and When used with less sticking; made of sintered abrasive with a dark blue after firing, can not afford the mesh cracks, no rust features, suitable for the manufacture of ceramics, resin, high consolidation abrasive and grinding, polishing and so on. Xia Teng Yuan Environmental Protection Materials Co., Ltd. sales of brown corundum salient features prominent small crystal impact resistance, due to the use of self-grinding machine crushing, mostly spherical particles, the company sold corundum abrasive manufacturers wholesale, the price is protected, suitable In all types of rough grinding, deburring processing. Advantages: cutting ability, does not damage the original shape of the workpiece. But only for the hard material of the workpiece, but also easier to polish.

Sand blasting abrasives Fused brown alumina BFA Brown fused alumina is made of bauxite/anthracite coal. Abrasive tools made by brown fused alumina are suitable for metal with high tensile(like: steel, malleable iron, bronze etc).and suitable for grinding, polishing, blasting precision casting, and also for refractory material. Brown fused alumina with characteristics like: high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion resistance, high temperature, high strength.

Brown fused alumina is fused and crystalized under high temperature from a mixture of bauxite and other raw materials. It is characterized by its high hardness, good toughness and sharp shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel, general purpose alloy steel, annealed malleable cast iron and hard bronze, etc. It also can be used as refractory materials.

Brown Aluminum Oxide P Grains Introductionï¼? Brown Aluminum Oxide is made by electric arc furnace smelting under high temperature with the raw materials of bauxite, anthracite and scrap iron. The significant chemical composition of brown aluminum oxide is aluminum trioxide (chemical formula: AL2O3). It is characteristic by high hardness, high toughness, and high abrasion resistance. The brown aluminum oxide P grain has more aggregative in distribution than F grain, with features of sharpness and evenly distributive, brings more efficiency for surface treatment. Brown fused aluminum oxide P grain is widely used in coated abrasive such as abrasive cloth, abrasive paper abrasive belts, etc.

Smelting of black fused alumina powder The smelting method of black fused alumina is basically same with smelting of brown corundum. The production method of black fused alumina is choosing high-quality bauxite, iron oxide and other raw materials, add other trace elements, carefully smelting in dumping-type electric arc furnace , to ensure that the massive black fused alumina block are top grade, less impurities, ,stable quality. This laid solid foundation for producing period of black fused alumina sand , grain size black fused alumina sand and black fused alumina powder that are of moderate hardness, good toughness, good using performance and stability quality. Prices of black fused alumina powder In the abrasive products, brown fused alumina, white fused alumina, black fused alumina are same in using bauxite as main raw material, add iron scrap in high-temperature electric arc furnace smelting, and why the price of black fused alumina is lower than price of brown fused alumina and black fused alumina , The price of aluminum in the market than the price of iron per ton to be much higher, brown fused alumina sand content of more than 95%, while the black fused alumina a sand content of aluminum oxide To 85%, we can see the same level of fused alumina aluminum content is much higher than black fused alumina, and fused alumina products in the most valuable component is alumina, therefore, the price of black fused alumina is much lower than white fused alumina and brown corundum.
