In order to investigate the breakage behavior of the feed in industrial secondary ball mills, the breakage characteristics of fine magnetite were analyzed. Magnetite particle breakage produces a bimodal particle size distribution that is consistent with the typical breakage characteristics of abrasion. The secondary ball mill can increase the surface area by reducing the diameter of steel ...

Just wondering if anyone has a ball or SAG mill with a trunnion magnet to remove scat steel and if they are willing to share the results. Looking into getting one for our SAG mill but looking for proof that it actually creates power savings, ball consumption savings, etc to justify the project. We process gold ore at about 200 TPH. Thanks!
