ball-mill sized feed. Feed ore with a top size of up to 200 mm (8 in.) and water enter the feed end of a SAG mill through a feed chute; the ore is milled in the shell and milled product exits through grates and pulp lifters at the discharge end (Fig. 1). The discharge is screened and the undersize, typically less than 12 mm (0.5 in.), provides ball
