Grinding media management in ball mills. Grinding ball additions. Grinding balls should be added each shift. Mill performance is negatively impacted when the mill is not drawing power at targeted level. This results in coarser grind size or loss in throughput. The grinding balls can be added onto the mill feed conveyor when the mill is running.

materials, or for fine grinding in general. Ball mills can blend and grind at the same time, yielding a fine, intimate mixture. Conventional ball mills are usually limited to a particle size of 1µ after one hour of grinding since gravity causes the particles to fall out of the grinding zone (between the media).

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
