Product Description
Calcined bauxite is one of the principal ore of aluminum. Rotary kiln calcined bauxite is obtained by calcining superior grade bauxite at high temperature (from 850ºC to 1600ºC) in the rotary kiln. 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%.
Besides, through calcination, the density and refractory resistance will also be improved to varying degrees. The grade of bauxite can be increased greatly.
The calcined bauxite can be processed into bauxite sand and bauxite powder of different particle sizes, both of which can be directly used as refractory sand. It has a very high status in the field of refractory materials.
Features and advantages of our Refractory grade calcined bauxite :
1)low iron (Fe2O3) content ,less than 2.0%,
2)2)big bulk density
3) other impurity is very low,as we select raw material for one time and second time after discharge from furnace 4)efficient supplying capability
5) competitive price and strict quality management
Application of our refractory calcined bauxite:
high alumina refractory bricks,corundum bricks, refractory castable
Specification of our hot seller Refractory grade CALCINED BAUXITE:
