Rotary kiln calcined bauxite is obtained by calcining superior grade bauxite at high temperatures (from 850 to 1600) in the rotary kiln. This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57% to 58% in raw bauxite, calcined bauxite has an alumina content of 84% to 88%. Besides, through calcination, the density and refractory resistance will also be improved to varying degrees. The grade of bauxite can be increased greatly.
As we all know, China is the world's leading supplier of bauxite, producing over three million tons per year for refractory, abrasive, and welding applications. Calcined bauxite is made of excellent bauxite ores, fired in a kiln to impart its superior abrasive qualities, hardness, and long-term frictional resistance. This materials are in stable index, homogeneous structure and excellent high-temperature performance. Its high alumina and low iron make calcined bauxite be the ideal raw material in refractory and abrasive products.

Brown Fused Alumina (BFA) is produced by a reduction fusion of high quality bauxites in electric arc furnaces. It is both a hard and tough material with high strength, making it an excellent abrasive grain for applications such as grinding wheels, sandpaper, blasting media, metal preparation, lapping, polishing, and grinding. Its thermal properties make it an excellent raw material for refractory applications. Application Range Abrasive: Produce ceramic grind wheel, resinoid grinding wheel, Grinding stone, Grinding block, sand paper, sand cloth, sand belt, polish wax, abrasive paste, coating etc.. 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 furnace etc.. Sandblasting abrasive: Mainly used for various material workpieces to decontaminate, derusting, prevent corrosion, remove oxide skin etc.. Abrasion resistance ground: Mainly used for non-slip of airport and road, chemical factory board paving. Precision casting: Investment casting technics of stainless steel and aluminium casting in coating.
White Fused Alumina (WFA) is kind of electro-corundum, which produced by controlled melting of alumina in an electric arc furnace. Its iron-free, ultra purity and extremely hardness make it as excellent materials in sandblasting, precision casting, abrasive and refractory.
SEPPE Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants. The color of cenospheres varies from gray to almost white and their density is about 0.4-0.8 g/cm�³, which gives them a great buoyancy. Flows like a liquid, with the appearance of a powder. Provides lightweight bulk to a varied and expansive range of compounds. Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.
Garnet as a natural abrasive can be used for waterjet cutting because of its high hardness, high cutting speed. It is a cost-effective alternative to silica sand, mineral slags and steel grits and shot as the perfect symbiosis of grain size, density and hardness/durability creates the optimum abrasive efficiency, lowest abrasive consumption (kg/m2) at the highest production rates (m2/hr). Compared with rock garnet, river garnet sand can keep the cutting surface smooth and flat. Because river sand is formed after a long time of impact, so its grain edge surface is more rounded, less damage to the material. Products cut from river garnet are more popular with consumers. -Sharpe Angular Edges; -High Hardness, Faster Cutting Efficiency; -Uniform Size Distribution, No Stuck in Nozzle; - No Free-Silica.
SEPPE Garnet is an integrated garnet mining, processing, shipping and distribution organisation providing the best quality industrial garnet for the surface preparation and waterjet cutting industries. It is a cost-effective alternative to silica sand, mineral slags and steel grits and shot as the perfect symbiosis of grain size, density and hardness/durability creates the optimum abrasive efficiency, lowest abrasive consumption (kg/m2) at the highest production rates (m2/hr). SEPPE garnet for waterjet cutting, they're extracted from almandine, since it is more angular in form, more efficient in cutting. Mixed with very high pressure water, garnet is used to cut steel andother materials in waterjets. SEPPE garnet for sandblasting, it is a alluvial garnet grains which arerounder, more suitable for blasting treatments.

Provides lightweight bulk to a varied and expansive range of compounds. Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers. Cenospheres are now used as fillers in cement to produce low-density concrete. Some manufacturers have begun filling metals and polymers with cenospheres to make lightweight composite materials with higher strength than other types of foam materials. Such composite materials are called syntactic foam. Aluminum-based syntactic foams are finding applications in the automotive sector. Silver-coated cenospheres are used in conductive coatings, tiles and fabrics. Another use is in conductive paints for antistatic coatings and electromagnetic shielding.
