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.

Clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. The composition of clinker, such as free lime, has to be closely monitored to ensure the quality of the cement.
Class silicate cement clinker grinding process in cement produce a representative sample, with limestone and clay as the main raw material, after crushing, raw ingredients, fine grinding is made, and then feeding calcined mature material, in cement kiln and clinker and a moderate amount of gypsum (sometimes mixed with mixed material or ...
The proposal is to add up to five percent finish mill additives during the cement manufacturing process. These additives are softer than the clinker they replace. Therefore, less energy is used in the grinding and mixing of clinker, gypsum and mill additives. Limestone is not available at the cement manufacturing location.
Dec 08, 2014· re Clinker grinding with limestone. Hello Shastri, 100oC seems a bit low. Normally you should try to keep the mill outlet temperature at between 110 and 115oC. Have you tested the water content of the cement blocking the diaphragm? If you use water sprays they may not be atomising correctly, causing localised buildup of moist cement.

Sweden: Cementa's Skövde plant working on project to optimise its grinding process and reduce the clinker factor of the cement it produces. The project is looked at grinding limestone separately as opposed to grinding it with clinker and gypsum, which it currently does. The plant is using a mill it only uses occasionally to grind the limestone to the desired size.
Portland Limestone Cement Part I - Preparation of Cements 1340 İnan Sezer [5] investigated the physical and mechanical properties of cements prepared by replacing 0-6-21 and 35% of clinker with limestone by intergrinding method. The time required to obtain a Blaine value of 330 m2/kg has been determined. All other blended
Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
