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%.
