The raw materials needed to produce cement are generally extracted from limestone rock, chalk, clayey schist or clay.They are then crushed and transported to the plant where they are stored and homogenized.The raw material is preheated and then sent to the kiln.


used at present. This consists of grinding the individual raw materials and feeding at controlled amounts into a rotary kiln and burning until they fuse into small lumps or balls called clinkers. In the wet process, a slurry of the blend is fed into the rotary kiln. The clinkers are cooled and then ground in two operations.
