1) Overload in overflow ball mills is due to the approach to a critical axial flow velocity for pulp of 0 072 m/s 2) While so far important only with 5 0 and 5 5 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
