1. Calcined Bauxite Introduction
Calcined bauxite is produced by sintering/calcining with natural bauxite ore of low iron, low alkali at temperatures of 1600 - 1800 degree Celsius in the rotary kiln or round kiln through pre-heationg, calcination, cooling and other processes. During Calcining, it can be removed impurities and improving the content of alumina. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.
