Optimization of mill performance by using
From 74% the media angle exponentially increases with pulp solid content. Unstable milling conditions starts to occur. The Sensomag® clearly detects the load expansion. (Figure 8.) This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate.

Technology Trunnion Magnets worldwide Delivers Quick .
In a typical grinding mill application, the grinding media eventually fractures and wears into a fine metallic powder because of the heavy re-circulating load in the mill. Energy is unnecessarily wasted to mill the milling media. As shown in Figure 3, the trunnion magnet is mounted at the ball mill discharge point to replace a trommel screen.

The grinding media load can be readily
Grinding media fill up about one third of a mill. The grinding media load can be readily measured. The grinding media load can be determined from the mill diameter and the distance between the top of the load and the top of the mill. To get an accurate number for steel media, the mill must be ground out before a measurement is taken. For AG and SAG mills a grind out would reduce the amount of
