Dec 24, 2018 Alumina Rotary Kiln Description Rotary kiln is thermal equipment for the sintering of alumina clinker. During manufacturing alumina, alumina bauxite, pure alkali and lime are proportionally loaded into rotary kiln, calcined at 12001300, the calcined bauxite clinker needs to be further processed to make Al OH3.
Aug 01, 2013 The production process of alumina rotary kiln. The shape of an alumina rotary kiln is a cylinder with angle of inclination . Pulverized coal is sprayed into the burning zone through the primary air that is 15 m away from the kiln head. They then will combine with secondary air which comes from bottom to cool the high temperature material, burn in high temperature, and release a lot of heat.
