ball mill and screen circuits iron wx; Grinding Circuit - an overview | ScienceDirect Topics. The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible.Grinding Ball Fragments in the milling circuit impact on two critical areas. One is the crushing circuit where companies have observed damage to crushers, unscheduled downtime and loss of production. The other is the grinding circuit where companies have discovered wear to pumps, sumps, piping, hydrocyclones, mill liners as well as inefficient
