Addition of Grinding Balls Watch raw mill SEC daily and add grinding balls in right timing →10% energy saving expected Ball diameter shrinks as time passes due to erosive effect. This leads to gradual increase of raw mill SEC. Filling level of grinding balls is also important in grinding efficiency. Optimum level of filling should be maintained.

subsequently cement entails three major functions: kiln feed preparation, clinker production, and finish grinding9. 1) Kiln Feed Preparation. Using dry or wet processes, mineral inputs are reduced to ground meal (powders or slurries, respectively) before they are sent to kilns for clinker production.
