Product Description

 

 

product description:

Calcined bauxite is one of the main ores of aluminum. Calcined bauxite contains hydrous alumina and aluminum hydroxide and is formed by post-catalysis of aluminum-bearing rocks in tropical and subtropical regions. Calcined bauxite is obtained by calcining (heating) high-quality bauxite at high temperature (85°C to 1600°C). Moisture is removed to increase the alumina content. Calcined bauxite has an alumina content of 75% to 90%, compared to approximately 57% to 58% alumina in primary bauxite. Heating takes place in a rotary kiln.

 

application:

Calcined bauxite is generally classified according to its intended commercial application, such as abrasives, cement, chemical, metallurgy, and refractories. As raw materials for high alumina and super refractory bricks and profiles, plastics, refractory castables, engines, gun mixtures, ramming materials, abrasives and other products.
