Fig: Manufacture of Cement by Dry Process. b) Wet Process The raw materials are firstly crushed and made into powdered form and stored in silos. The clay is then washed in washing mills to remove adhering organic matters found in clay. The powdered limestone and water washed clay are sent to flow in the channels and transfer to grinding mills
