It is used to estimate the energy require as affected by the cooling process, plays a significant role in ment for grinding the clinker to a given fineness. There are grinding. Airquenched clinkers were found to be more several different laboratory testing methods developed for grindable than those cooled by planetaries . determining the grindability of clinkers.
The last stage of making cement is the final grinding process. In the cement plant, there are rotating drums fitted with steel balls. Clinker, after being cooled, is transferred to these rotating drums and ground into such a fine powder that each pound of it contains 150 billion grains. This powder is the final product, cement.
