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.

CLINKER GRINDING UNIT PROCESS - Mechanical engineering ...

Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills. Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter - grinding in mills.

Cement clinker - Wikipedia

Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall. Organic compounds are also often added as grinding aids to avoid powder agglomeration. Triethanolamine(TEA) is commonly used at 0.1 wt. % and has proved to be very effective. Other additi

What is the purpose of adding gypsum in cement?

Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.

Cement Milling - Understanding Cement

Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL Smidth VRM. As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 4.2H 2 O).
