Refractory Bauxite Rkb 87 Calcined Bauxite 87% Aluminum Oxide Compounds Rotary Kiln Bauxite

Calcined bauxite is a product of raw bauxite calcination which mainly consists of aluminum hydroxide. Calcination takes place in temperature 1650-1700oC in a shaft or rotary kiln. Rotary kiln bauxite has better characteristics than shaft kiln bauxite, in particular higher content of Al2O3, lower porosity and bulk density.
Rotary kiln bauxite is the bauxite produced by rotary kiln. There are three kinds of kilns for bauxite production: rotary kiln, shaft kiln, and round kiln. Comparing with the other two kinds, rotary kiln bauxite is calcined more evenly, benefits from the continuous rotary movement of the kiln body. Calcined Bauxite is obtained by calcining and heating superior grade Bauxite at high temperatures (from 850ºC to 1800ºC) in rotary kiln bauxite. This removes moisture, thereby increasing the alumina content, meanwhile, the high refractory mineral phases corundum and mullite are formed.
