Charging Grinding Media Grinding Classification. 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.
Although the amount of the media charge is application dependent, a good rule of thumb to start with is 50. A good starting point for material loading is to have enough material in the mill to fill all of the voids and just cover the grinding media. The point at which the charge breaks away from the periphery of the mill as it is carried upward.
