  • Brochure: Ball Mill/SAG Mill Ball Separator

    Eriez announces the availability of a new, FREE, full-color brochure that describes the many features and benefits of the Eriez Trunnion Magnet. This revolutionary magnetic 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, pump life is extended and throughput is increased.

    The brochure explains that 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 discharge 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.
