Product Description

 

Product Description

Bauxite Sand (Powder) is a new senior aluminasilica refractories. It can be used as coating or stuccoing for lost wax casting and refractory aggregate for kinds of casting coating.
 

It 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.

It is typically calssified according to its intended commercial application,such as abrasive,cement, metallurgical and refractory.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.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.

 

2.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.

 

3.Calcined Bauxite for aluminum refining Industry

It can be used for national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities.

 

4.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.
