Cement Manufacturing Process How the Cement is Made
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.
