Magnetic Separator reduces downstream equipment damage.

June 17, 2005 - Trunnion Magnet Separator removes up to 98% of grinding media steel balls and ferrous chips from milled ore in SAG/ball mill operations. Positioned at downstream end of mill, arc of permanent magnets surrounding almost half of blind trunnion extension attracts and holds steel balls to inner surface of trunnion. Steel balls are carried to top of trunnion, where magnetic arc terminates, thereby releasing balls that then fall into hopper and chute.

Mineral and Mining Innovation from Eriez Magnetics Reduces Damage to Downstream Equipment

Eriez Magnetics' Trunnion Magnet Separator effectively removes up to 98 percent of the grinding media steel balls and ferrous chips from milled ore in SAG/ball mill operations. By eliminating these potentially destructive pieces, harm to downstream equipment is significantly reduced.

As ore is discharged, it is mixed with residual and broken steel balls that are harder than the ore. If these rigid steel balls are not removed from the process, it often causes extensive and costly damage to the pumps and cyclones that are located downstream.

Positioned at the downstream end of the mill, the Trunnion Magnet consists of an arc of permanent magnets surrounding almost half of a blind trunnion extension. As the trunnion rotates, the powerful magnetic circuit aggressively attracts and holds the steel balls to the inner surface of the trunnion. The steel balls are carried to the top of the trunnion where the magnetic arc terminates, thereby releasing the balls, which subsequently fall into a hopper and chute.

The Trunnion Magnet is available in several design variations to accommodate specific ball mill configurations.
