CLINKER GRINDING IN CEMENT PRODUCTION

21-02-2019  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.

Lower CO2 cement production with activated clay. Clinker is the most important component in making cement a hydraulic binder. For years, cement manufacturers have been striving to reduce the so-called clinker factor – the proportion of clinker in cement – by adding additives. This is because the higher the proportion of clinker, the more CO2 is released during cement production. The polysius® activated
