 · Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose but presents the problem that the maximum temperature of the feed inside the kiln is over 1400°C while the gas temperatures reach 1900°C.

Cement Kilns Rotary kilns

 · With the arrival of rotary kilns in Britain in 1900 cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water to form a slurry containing typically 30-45 water or they were ground dry to form a powder or "raw meal".
