    The same policy is employed for the make-up charge where adding different ball sizes is done in order to optimize the mill performance. Chimwani et al. (2015) developed a simulation program that could predict optimal make-up balls to be added in order to achieve a required product fineness. Ball mills of greater length are termed "tube mills " and when hard pebbles rather than steel balls are used for the grinding media the mills are known as "pebble mills. In general ball mills can be operated either wet or dry and are

  • Mill (grinding)Wikipedia

    Ball mills normally operate with an approximate ball charge of 30 . Ball mills are characterized by their smaller (comparatively) diameter and longer length and often have a length 1.5 to 2.5 times the diameter. The feed is at one Add to this another 10 -15 above the ball charge for total of 23 to 25 product loading. So as a rule of thumb we use 25 solid loading. Empirical Check Once the mill has been loaded and run for a few minutes open the cover and look down into the mill.
