Ball Mills Mineral Processing Metallurgy. Ball Mill Charge volume. The mill power is approximately directly proportional to the charge volume within the normal range. When calculating a mill 40 charge volume is generally used. In pebble and ball mills quite often charge volumes close to 50 are used.
