The SAG mill discharge is classified on a trommel screen. In this application the SAG mill discharge is treated with a Trunnion Magnet or a drum type magnet to collect the grinding media as it discharges the mill. The Trunnion Magnet is replaces the trommel screen and removes grinding ball fragments directly from the mill discharge.

The Eriez Trunnion Magnet is a powerful system for the automatic separation and removal of processing balls and ferrous chips from milled ore in ball or SAG mills. Typically the system consists of a permanent magnetic arc that partially covers a rotating blind trunnion positioned at the ball or SAG mill discharge.
