In overflow ball mills this slurry toe extend up to at least the point where it can overflow out of the discharge trunnion. As flow requires a gradient, the slurry toe position in an overflow ball mill will actually be higher than the lowest point of the discharge trunnion and as flow increases the slurry toe will become progressively higher.
