Chat OnlineGRINDING BALL CHARGING EQUIPMENT GRINDING MEDIA . During the grinding process grinding balls are consumed due to abrasive wear and must be replaced progressively (and ideally continuously) to maintain the optimum charge within the mill. Safe and reliable feeding and delivery of new grinding balls to the mill is a key concern for many mine
Chat OnlineWhen charging a grinding mill the standard practice is to dump tons of balls into the mill at once and replace them somewhere between once a shift and once a week. It s an inefficient practice that wastes energy impacts product particle size distribution and risks breakage of mill linings and grinding media.
Chat OnlineMedia to media contact for rods mills is linear rather than point to point (as with balls) and are much heavier. The larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded. This leads to a narrower size distribution and significantly less slime compared to ball mills.
