Brown fused alumina powder using calcined bauxite, coke, and iron by controlled melting in an electric arc furnace at a high temperature. Bauxite Used for producing BFA contains high α-Al2O3. After the fusion process, the materials are mixed and fused into liquid materials, then cooled down and crushed(milled)into lump sizes. The lump sizes are then ground into finer grades or powders. Brown fused alumina has high compression strength, toughness, excellent self-sharpening, low thermal expansion coefficient, and excellent hydrophilia and cleanliness.
The process of brown fused alumina fine powder 0-1mm for refractories:
Calcined bauxite is broken into crushing machine — elevating– roll crusher mill– sizing —magnetic separator —fine sieve —water washing (acid washing )—package (25kg/pp bag or paper bag,40 bags/ton bag or pallet )

Application of brown fused alumina fine powder 0-1mm for refractories:
1. Abrasive: Produce ceramic grind wheel, resinoid grinding wheel, Grinding stone, Grinding block, sandpaper, sand cloth, sand belt, polish wax, abrasive paste, coating, etc.
2. Refractory material: Mainly used for abrasion and high temperature resistant, inoxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy, various industrial stoves, electric furnaces, etc.
3. Sandblasting abrasive: Mainly used for various material workpieces to decontaminate, derusting, prevent corrosion, remove oxide skin, etc.
4. Abrasion resistance ground: Mainly used for non-slip of airport and road, chemical factory board paving.
5. Precision casting: Investment casting technics of stainless steel and aluminium casting in the coating.
The best way to have abrasive products retain maximum performance and work life is to store them properly. The bonding and backing materials used in abrasives are very sensitive to changes in temperature and humidity. Abrasives are best stored at temperature levels of 60 to 80 degrees Farenheit and a
Silicon carbide (SiC) is produced from coke and quartz sand applying the Acheson process in an electric resistance furnace. When petrol coke and quartz sand are grouped around a graphite electrode and heated to a temperature of 2,000°C, black and slightly higher-quality green SiC are obtained. Green SiC has a
Generally, we suggest to make shipment by sea which costs less. We also can follow other transportation method you asked.
Grit size typically runs from coarse (16 -24 grit), medium (36 – 60 grit) and fine (80-120 grit). Superfine grits run from 150 and higher. Grinding wheels usually will be between 24 and 100 grit. Honing stones and jointing stones and other polishing abrasives will be 150 grit and higher.
When processing minerals in a furnace, materials can either be melted or sintered. When materials are melted during the production process the minerals go from a solid state, to a liquid state, then is re-solidified during the cooling process creating uniformity in the chemistry throughout the entire batch. The sinerting process
Structure is basically the spacing between abrasive grains. An open structure would be 12 or higher while a closer structure would be 6 or so. Here again, the structure depends on a variety of factors not the least of which is how difficult the material is to grind.
