The turbulence condition of slurry in a mill can be further visualized by observing the movement of the ball charge. If the slurry is not too viscous the rotation of the mill can create a strong turbulence in the slurry due to the movement of the ball mass up against the pool of slurry suspension (see Fig. 7). In addition the rolling of cascading balls down into the suspension should also increase the degree
