New Eriez® White Paper Highlights Magnetic Separation Techniques to Improve Grinding Efficiency

October 06, 2014 - "White Papers"

Erie, PA---Eriez® announces the release of its newest white paper for the minerals processing industry, “Magnetic Separation Techniques to Improve Grinding Circuit Efficiency –2014.” This informative piece offers an in-depth exploration of how Trunnion Magnets provide tremendous cost savings by efficiently separating and removing balls and broken ball pieces typically used for ore processing in ball/SAG mill operations.

The white paper--written by Jose Marin, Eriez Director of Materials and Minerals Processing--specifically focuses on a few of the 150 Trunnion Magnet installations around the globe. It describes the application/circuit location and the accompanying technique/equipment solution.

Application photos and diagrams are included for each highlighted application. Tables and graphs illustrate the significant advantages and measured improvements customers attain when a Trunnion Magnet is installed.

This white paper represents a current view of the effects of grinding ball fragments in the milling circuit and the impact on the crushing and grinding circuit. The performance of a Trunnion Magnet should be compared to the existing operations, especially if cost savings and output need improvement.

“Magnetic Separation Techniques to Improve Grinding Circuit Efficiency –2014” is offered online through Eriez’ Orange University®, the program through which the company gives customers access to an array of free online and offline educational resources.
