After exiting the cement kiln, the clinker is cooled and stored. To produce cement, clinker is mixed with a small amount of gypsum and other additives, such as pozzolans or slag. This mixture is then ground in the cement ball mill. The grinding process involves passing the clinker and additives through the rotating drum of the ball mill, where ...

Figure 1 shows the areas of high energy consumption in a cement plant. The numbers clearly indicate that grinding of both raw meal and cement needs highest attention. Grinding by design is a very inefficient process. However, the ball mill has been the industry's workhorse for over a century and has been one of the inefficient ways of operation.
