Advantage Of Wet Grinding In Cement Manufacturing

As a result, the inefficiency of the wet process is an advantage—to the manufacturer. What is the purpose of adding gypsum in cement? During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the "setting of cement".
