alumina rotary kiln

Aug 01, 2013 · 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
