Eriez® Trunnion Magnets Protect Downstream Equipment
Erie, PA -- Eriez®Trunnion Magnet Separators effectively remove 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, damage 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.
Powerful magnetic circuits provide maximum performance to help extend pump and hydrocyclone life and increase milling throughput by as much as five percent. Depending upon mill capacity, ball size and other parameters, Eriez will select and specify the appropriate construction features.
