## Optimization of continuous ball mills used for finish

The L/D ratio of the ball mill was varied in four steps of 175, 21, 279 and 349, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25% The experiments clearly indicated that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness

## Optimization of continuous ball mills used for finish

State of the artL/D ratio and ball charge filling ratioThe specific power consumption is, as already said, influenced by the L/D ratio and the ball charge filling ratio of a ball mill The investigations known from the literature were carried out with two compartment cement mills in the 1980s (Kuhlmann, 1985, Tätigkeitsbericht, 19)
