Consequently the whole ball charge has a tendency to slide down This shortens the moment arm "m" which reduces torque and mill power despite the fact that we are continuing to add feed (Actually one must also remember that as one adds feed, mill retention time decreases which technically will hold "W" approx constant)

1) Overload in overflow ball mills is due to the approach to a critical axial flow velocity for pulp of 0072 m/s 2) While so far important only with 50 and 55 m diameter mills, it should be found with smaller mills in combinations of very high circulating loads, excessive L/D ratios, very soft ores or coarse grinds 3 A proper balancing of lower Lf and higher F values can reduce the risk
