Cement Production Process Wet Vs Dry Ppt

Dry Process. 1. This method is adopted when the raw materials are hard. 2. The quality of cement prepared by this method is inferior. 3. The dry process is slow, difficult and costly. 4. Raw materials are fed into the rotary kiln in the form of a slurry. 5. This method is rarely used now a day. Wet Process. 1.
