Experimental study of charge dynamics in a laboratory …

 · 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 ...

BALL MILL CUTTER

2018-1-4 · The drive of the ball mill consists of an induction electric motor, two-stage gearbox and the pinion gear. This pinion gear is mated with the girth gear mounted on circumference of the ball mill shell and in that way it transfers the motion from the drive to the shell, see Figure 1, taken from [1]. Figure 1. Mechanical system of a ball mill ...
