CLINKER GRINDING IN CEMENT PRODUCTION

Feb 21, 2019· Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.

Why adding of gypsum to cement? - Education Club 24hrs

May 31, 2020· The setting time of the cement is adjusted by putting more or less gypsum in with the clinker when it is being ground. The gypsum affects the reactions of the aluminate phase (C3A) in the Portland cement to moderate the setting time. Adding an excess of gypsum can produce "false set" where the gypsum itself sets quickly, before the cement does.
