In the dry process, the raw materials are crushed first and dry mixed. Contrarily, in the wet process, the crude ingredients are wet-ground i.e., water is added whilst their crushing. Both of these methods are discussed in detail. The figure below delineates the general process diagram for the manufacture of cement.
