2004-12-10 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.
