Erie, PA—Eriez® announces the release of the company's new white paper, “Trunnion Magnet Technology Delivers Quick Payback.” According to the white paper, performance metrics collected through studies conducted among installations of Eriez Trunnion Magnets worldwide indicate a six-month to one-year payback when compared to trommel screen installations.

This white paper, written by Eriez Director of Mining and Minerals Processing Jose Marin, explains how Trunnion Magnets function, highlights their performance advantages, describes retrofitting options and provides detailed economic justification, including guidelines to assess savings potential.

A graph illustrates how kilowatt usage can be reduced by as much as 750 kW/day or eight percent. According to the white paper, cost estimates of a typical 18-foot diameter 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. 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 hydrocyclones.
