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.
