Product Description

 

Product Description

Calcined bauxite is a general term for a rock composed of hydrated aluminum oxides. It is the main ore of alumina to make aluminum.Also used in the production of synthetic corundum and aluminous refractories. 
 

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% to 88%.the heating is carried out in rotary kilns.

As raw material for use in high alumina and super duty refratory bricks and shapes ,plastics ,castable refratory, motors, gun mixes, ramming mixes, abrasive grains and other products chemical composition.

Application

1.For refractory material. It has the properties of high alumina, low iron, stable thermal chemical performance and so on , thus it is the main raw material of producing alumina and artificial corundum refractory materials.

2. For Precision casting. The bauxite clinker is processed into fine powder to form a mold and then precision cast. 

3. For usage on refractory products. High bauxite clinker has a refractoriness of up to 1780°C, strong chemical stability and good physical properties. 

4. For Manufacturing high alumina refractory cement.

5. For High fraction surface coating. Such as anti-skid road surface treatment.
