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
ADVERTISEMENTS: Portland cement can be manufactured by intimately mixing together calcareous and argillaceous stones containing silica, alumina, and iron oxide etc. and burning it in large rotary kilns at a temperature of approximately 1400°C to 1500°C. At his temperature the materials partially fuse, forming clinker. This clinker is cooled and ground to fine power. Usually […]
