Eriez Magnetics' trunnion magnet separator effectively removes up to 98% 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.

The trunnion magnet is an enhanced system for separation and removal of balls, chips or scats in a typical ball or SAG mill operation. The trunnion magnet is mounted at the SAG ball mill discharge point and is used in place of a trommel screen.

Mill trommels - flexible solution with long-lasting frames. Is your trommel performing at maximum capacity? Mill trommels, whether used for sizing or scalping, play a vital role in your grinding circuit. With as a partner, you get the best possible support for your trommel today, and are ready to meet the challenges of tomorrow.

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.

Oct 31, 2005· 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 ...

Jun 16, 2016· With More Than 100 Installations Worldwide, ... The Trunnion Magnet is mounted at the SAG mill discharge point and used in place of a trommel screen. It consists of a barrel or "blind trommel" that is mechanically attached to the trunnion or discharge of a ball mill. The barrel rotates around a fixed assembly of ferrite and Rare Earth ...

Eriez has released a white paper for the minerals processing industry titled Magnetic Separation Techniques to Improve Grinding Circuit Efficiency–2014, offering an in-depth exploration of how its trunnion magnets can provide significant cost savings by efficiently separating and removing balls and broken ball pieces encountered in ball mill and SAG mill operations.

chips or scats in a typical ball/SAG mill operation replaces the dead weight of ball magnets with fresh ore. By effectively removing 80 percent or more of the worn or broken media, the trunnion magnet reduces power consumption from the mill drive and prevents expensive damage to other equipment, such as pumps and hydroycyclones.

The SAG mill and all other grinding equipment is remotely monitored and controlled via computer from a central control room. The control room operator watches four video terminals and a CCTV monitor to keep track of critical process variables impacting mill throughput.

mill indicate savings of up to $100,000 per year. As explained in the white paper, there are hundreds of installations of Eriez Trunnion Magnets worldwide. This system for separating and removing balls, chips or scats in a typical ball/SAG mill operation replaces the dead weight of ball magnets with fresh ore.

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.

Eriez Magnetics says its trunnion magnet separator, available in several design variations to accommodate specific ball mill configurations, effectively removes up to 98% of the steel balls and ferrous chips from milled ore in SAG/ball mill operations.

Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components of any grinding mill.

The Trunnion Magnet is mounted at the SAG mill discharge point and used in place of a trommel screen. It consists of a barrel or "blind trommel" that is mechanically attached to the trunnion or discharge of a ball mill. The barrel rotates around a fixed assembly of ferrite and Rare Earth magnets, positioned on the outside of the barrel.
