     in this research the results of liner wear measurements at the sarcheshmeh copper mine sag mill (9.75 m ×4.87 m) was used to study the effects of liner wear impact on charge behavior. the largest difference in the angles of charge impact points after 3759 h of operation along the mill length was found to be 61o. for 5186h of operation in the region between 0.8 and 1.7 m from the feed end the average impact angle reached 311o which clearly showed rolling down of the charge to toe. the results indicated that the charge dynamics not only varies during the operation times but also changes significantly along the mill length.
