  • 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
