how to manufacture gypsum used in cement plants

Role of Gypsum in Cement and its Effects - The

In the manufacture process of cement, clinkers are formed. These cement clinkers are cooled down and added with small amount of gypsum. The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it

11.16 Gypsum Manufacturing - US EPA

mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco.

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”. If not added, the cement will set immediately after mixing of water leaving no time for concrete placing.
