Ball mill media optimization - Metcom Tech

parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change. • Population balance modelling was deemed unsuitable for this purpose. As noted by Meloy

Grinding Balls Rods - 911 Metallurgist

20/10/2016  In an operating mill a seasoned charge, containing media of all sizes from that of the renewal or replacement size down to that which discharges automatic ally, normally produces better grinding than a new charge. It is inferred from this that a charge should be rationed to the mill feed, i.e., that it should contain media of sizes best suited to each of the particle sizes to be ground. Usual practice is, however, to charge a new mill

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. This addition should be spaced over time to prevent overloading a section of the belt, plugging the feed, etc. If the mill
