Mill Power, kW KiloWatts Balls Fraction of the Total Mill Power Draw contributed by the Ball Charge. Overfilling Fraction of the Total Mill Power Draw contributed by the Overfilling Slurry on top of the "kidney". Slurry Fraction of the Total Mill Power Draw contributed by the Interstitial Slurry in the ball charge.
