    2019-03-14  Wet and semi-wet process cement kilns. Clays in general are both hydrophilic and fine, and clays milled alone produce pumpable slurries with 60-70% water content, although some comparatively rare "swelling" clays require much more water: a bentonite clay paste with 95% water is

  • Cement Kilns: Rotary kilns

    2019-03-14  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".
