Spreadsheet based modeling of liner wear impact on charge

01/12/2022 · A spreadsheet based software was developed to model the charge trajectory in tumbling mills using the methodology proposed by Powell 1991 2 The 3 D liner wear profiles at various operation hours were used to predict the charge trajectory along the mill length in a × m SAG mill at the Sarcheshmeh copper complex 3

Grinding Media Growth Steel

Media 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
