Cement Clinker an overview | ScienceDirect Topics

52 Raw Feed in Cement Clinker Production The cement clinker manufacturing process traditionally involves intimate mixing and the subsequent heat treatment of a blend of calcareous rock, such as chalk or limestone, and argillaceous rock, such as clay or shale A series of chemical reactions of calcium, silicon, alumina and iron oxides present leads to the formation of the clinker material

The cement kiln

The original rotary cement kilns were called 'wet process' kilns In their basic form they were relatively simple compared with modern developments The raw meal was supplied at ambient temperature in the form of a slurry A wet process kiln may be up to 200m long and 6m in diameter It has to be long because a lot of water has to be evaporated and the process of heat transfer is not very efficient
