Calcined Bauxite Powder Refractory Castables Bauxite Aggregate

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

What’s the detail of our calcined bauxite?

1).calcined bauxite has high refractoriness, good mechanical strength and moderate slag resistance.

2).calcined bauxite is typically used in ladle working lining, tundish furniture, delta sections, general purpose repairment,aluminium melting furnace and mineral processing.

What’s the size of our calcined bauxite?

0-1mm,1-3mm,3-5mm,5-8mm,200mesh,325mesh,or as buyer’s request.

Clacined Bauxite Classification Introduction:

1. Classified according to the type of bauxite raw materials:

(1) raw bauxite, alumina original ore (natural sedimentary rock class).

(2) the calcined bauxite, the raw bauxite after high temperature calcination (1200 ~ 1700 ℃) is called the calcined bauxite.

2.Calssified according to the different calcining kiln where the bauxtie is divided into:

(1)Shaft kiln bauxite

(2)Rotary kiln bauxite

(3)Round kiln bauxite

3.Calcined Bauxite according to different uses for division:

(1) the refractory grade bauxite

(2) the grinding grade alumina

(3) the welding grade bauxite

Calcined Bauxite Applications:

1.Calcined bauxite in aluminium industry. Used for defense, aerospace, automotive, electrical, chemical industry, daily necessities, etc.

2.Calcined bauxite in the precision casting. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.

3.Calcined bauxite used for refractory products.

4.Calcined bauxite in aluminum silicate refractory fiber. Used in iron and steel, nonferrous metallurgy, oil, chemical space of atomic energy, defense and other industries.

5.Bauxite for pouring ladle whole ladle lining

6.Bauxite rock for alumina cement, abrasive materials, ceramic industry and the various compounds

7.Powdered bauxite can be fused into tiny beads at very high temperatures. These beads have a very high crush resistance, and that makes them suitable as a proppant.
