  • Optimization of continuous ball mills used for finish

    The L/D ratio of the ball mill was varied in four steps of 1.75 2.1 2.79 and 3.49 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.
