Cement Kilns: Rotary kilns

Cement Kilns: Rotary kilns

Rotary Kiln Processes 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".
