Refractory Grade Calcined Bauxite 0-1-3-5-8mm Chemical Composition: Al2o3 70min

Calcined bauxite is one of the principal ore of aluminum. Rotary kiln calcined bauxite is obtained by calcining superior grade bauxite at high temperature (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 70% to 85%.
Besides, through calcination, the density and refractory resistance will also be improved to varying degrees. The grade of bauxite can be increased greatly.
The calcined bauxite can be processed into bauxite sand and bauxite powder of different particle sizes, both of which can be directly used as refractory sand. It has a very high status in the field of refractory materials. We are not only bauxite supplier, but also your loyal partner who can provide qualified products.
Calcined Bauxite for refractory material
Such calcination of bauxite has the properties of high alumina, low iron, high hardness, small thermal expansion coefficient, high refractoriness, and stable thermal chemical performance, so it is the main raw material of producing alumina and artificial corundum refractory materials.
Calcined Bauxite for precision casting
The alumina clinker which is processed into fine powder and made into cast mould can be used in military, aerospace, communications.
Calcined Bauxite for aluminum refining Industry
It can be used for national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities.
A Calcined Bauxite for high friction surface coating
Calcined bauxite has 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.
Besides, calcined bauxite also can be used in making refractory bricks, cement, castable and welding flux, etc.
