2021-10-9 The production process of gypsum products can be broken down into four stages: exploration, quarrying, processing, panel production. The data resulted from the first process, i.e., the exploration process is used to determine the configurations of the components used in the later stages of gypsum production.

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. Advertisements
