CLINKER GRINDING IN CEMENT PRODUCTION
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 Milling
This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O.
Oman Cement unveils initiatives to boost capacity
The debottlenecking and enhancement project will lift the clinker production of Line 3 from 4,000 tonnes per day (tpd) to 6,000 tpd, while also boosting clinker quality, according to the CEO. Additionally, the company has decided to install a new cement mill (CM 6) with a packing and truck loading facility to meet increased cement demand.
A Comprehensive Guide to the Cement Manufacturing Process
This is done inside a ball mill where it is further mixed with a small proportion of Gypsum. Gypsum is important because it acts as a regulator of the cement's setting time and prevents it from early hardening after the addition of water. The ball mill pulverizes the clinker and gypsum into a fine powder.

Clinker
Clinker is the main ingredient used in the manufacture of Portland cement. Clinker is formed in lumps or nodules, usually 3-25mm in diameter, by sintering limestone and alumino-silicate (clay) during the cement kiln stage. Clinker is ground in a mill, usually with gypsum, to produce Portland cement.
