Effects of slurry pool volume on milling efficiency
Tangsathitkulchai [1] hypothesised that for an overfilled mill (see Fig. 1), a pool of slurry (1) forms at the base of the ball mill charge.A fraction of the ball mass (2) is submerged in the slurry. This fraction works against the stationary suspension of slurry causing a liquid drag on the interstitial particles.
