All the cement plants set up after 1980 use the dry process for the manufacture of cement. In this process, the calcareous materials such as limestone are crushed and stored in silos or storage tanks. The argillaceous material such as clay is thoroughly mixed with water in a container known as the wash mill. This washed clay is stored in basins.

This process was especially evolved to counter the main drawback of the wet process i.e. high fuel consumption. In this process, the raw materials ground in dry condition are homogenized and then nodulised in a pan noduliser of dish or rotary type by adding controlled quantity of water (10- 12 %).
Type of Process. There are mainly two types of Cement Manufacturing process: Wet Process; Dry Process; Wet Process. Under wet process type, the raw materials are mixed with water so as to ensure better homogenization which leads to better quality of clinker. In the whole process, moisture content in the slurry is 35-50%.
Fig 1: Cement Manufacturing. The process of manufacturing cement involves mixing the calcareous and argillaceous components in a 3:1 ratio. Following by mixing of the materials, two processes can be followed to arrive at the final product of ordinary portland cement. The two processes include. Wet Process; Dry Process; Wet …
