Minimization of variation in clinker quality
The cement is prepared by grinding the clinker in a coal mill. Recent studies have shown that the cement clinker variations have a greater effect on the workability and strength of cement. The unexpected variations may lead to serious disturbances in production in the form of poor compaction, too low early strength and strand slippages. This is causing increased waste in .

INVESTIGATION ABOUT THE EFFECT OF CHEMICAL GRINDING .
Cement grinding is a continuous process: the clinker/gypsum/additions blend is continuously fed at mill entry and extracted as fine fraction from separator. The mass of material sent back to the mill as coarse fraction can be several times the fresh feed, depending on the fineness required and separator type. For modern cements production, the mass of material moving through the .
Cement grinding Vertical roller mills versus ...
In the grinding process heat will be generated and the cement will be heated up. The temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process. It will typically be in the range from 90 to 120 deg. C. At this
Cement Manufacturing Process
Cooling and final grinding. After exiting the kiln, the clinker is rapidly cooled down from 2000°C to 100°C200°C by passing air over it. At this stage, different additives are combined with the clinker to be ground in order to produce the final product, cement. Gypsum, added to and ground with clinker, regulates the setting time and gives the most important property of cement, .
