2020-5-20The limestone powder is then mixed and blended with the other raw materials in differing proportions, depending on the type of cement being manufactured. These blended raw materials are stored in a silo before being fed into the cement facilitys kiln. It is burned at temperatures over 1500 to produce clinker.

There are three types of processes to form cementthe wet semi-dry and dry processes. In the wetsemi-dry process raw material is produced by mixing limestone and water called slurry and blending it with soft clay. In the dry process technology crushed limestone and raw materials are ground and mixed together without the addition of water. Get.

Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.
