Dimensionality in ball mill dynamics SpringerLink

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 ...
