Numerous torque mill tests, in addition to the growing plant data base compiled to date, show that media charging near the size that provides highest ball mill grinding efficiency provides a degree of robustness with changing ore grindability. It is rare that the media is incapable of breaking the largest particles as they become tougher.
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.
Jun 19, 2015 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.
