The main ingredient of bauxite also known as alumina is aluminum oxide. It is an earthy mineral colored white or gray white and could also appear to be brown yellow or light red due to iron inside it . Calcined Bauxite is produced by high temperature calcination. Product usage (1) Aluminum Industry. Used for national defense, aviation, automotive, electric appliance, chemical industry, daily necessities, etc (2) Precision Casting.Calcined bauxite powder can be used for produce mold precision casting and used for military industry, aviation, communication, instrument, machinery and medical equipment department. (3)Used for Refractory Product .The refractoriness of calcined bauxite could be as high as 1780 .And it also has excellent chemical stability and good physical properties. (4)Silicate Aluminum Refractory Fiber. With advantages such as light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical shock resistance .It can be used for steel, non-ferrous metallurgy, electronics, petroleum, chemical industry ,astronavigation , atomic energy, national defense and other industries. The calcined bauxite is added into the high temperature electric arc furnace which is about 2000 ~ 2200 and then process by high temperature melting, high pressure and high speed air or steam injection, cooling and then it become into Silicate Aluminum Refractory Fiber which is white as cotton.It can be pressed into fiber blanket, fiber board or woven into cloth to instead of high temperature industrial furnace lining brick of smelting, chemical , glass industry and other industry . Firefighters can use refractory fiber cloth to make clothes.¸Manufacture alumina cement, abrasive materials, ceramic industry and other aluminum compounds in chemical industry which for alumina produce.
1.Introduction of Bauxite: The main component of bauxite is alumina, which is hydrated alumina containing impurities and a kind of earthy mineral. The density of bauxite is 3.45g/cm3 and hardness is 1-3. Our company mainly supply bauxite clinker. It is also known as high alumina clinker. Bauxite clinker is mainly used for high alumina refractory products. The various high alumina brick is produced by bauxite clinker, which is widely used in the metallurgical industry and other industrys, especially in the top of electric furnace, blast furance and hot blast stove. 2.Specification of Bauxite: Grade Al2O3% SiO2% Fe2O3% Na2O% K2O% Density Water absorption N88 88 6±1 1.5±0.5 0.06 0.25 3.2 4 N85 85 8±1 1.6±0.5 0.06 0.3 3.1 5 N80 80 12±1 1.8±0.5 0.06 0.4 2.95 7

Calcined Bauxite,refractory Kiln Bauxite,80~90 Calcined bauxite is produced by sintering/calcining of low iron, low alkali containing raw bauxites at temperatures of 1600 - 1800 degree Celsius.In this calcination process the high refractory mineral phases corundum and mullite are formed. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.
Calcined bauxite has traditionally been the most commonly used aggregate material used for High Friction Surfacing.The inherent nature of Calcined Bauxite resists shear stresses that lead to polishing of the road surface. Its hardness is also beneficial in internal and external industrial flooring applications where a very hard and long lasting mineral is required to give high-friction, anti-slip performance.Calcined Bauxite has been found to exhibit characteristics far superior to alternative road surface aggregates.
Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85oc to 1600c) .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%to88%.The heating is carried out in rotary kilns.
