Ball Mill Filling Level Formulae
A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume (inside liners). B) Overflow Discharge Mills operating at low ball fillings – slurry may accumulate on top of the ball charge causing, the Total Charge Filling Level to.A Method to Determine the Ball Filling, in Miduk Copper. to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage The results obtained from this work show, the ball filling percentage variation is between 1.2– 3.7 which is lower than mill ball filling percentage, according to the designed.
