Optimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput. Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimising operational cost.

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.

Mill Charge An Overview Sciencedirect Topics

Since grinding effort is related to grinding energy, there is little increase in efficiency (i.e., delivered kWh t 1) above about 4050% of the critical speed. It is also essential that the cataracting medium should fall well inside the mill charge and not directly onto the liner, thus excessively increasing steel consumption.

Grinding Media is typically a bead of uniform size, shape, and density. The media is agitated in high concentration with a slurry (or mill base) to be ground. In a small media mill a central shaft agitates the media and slurry. Energy is transferred from that shaft to the nearest layer of beads and from that layer to subsequent layers of beads.
