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 be

load percentage calculation that belongs to mill diameter 𝐷 Ball volume in total mill load could compute by Equation 3. Mill Ball (%) = 100{[(ball volume in the 0.4 m3 sample)* 58.52] / 0.4}/297.96 (3) According to the results (Table 1), the ball filling percentage was obtained 1.3%. However, these results may have some field errors. Acquired Results from Abrasion Test Ball abrasion was

material in the mill including the media which may be steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semi-autogenous mill, as well as the slurry that makes up the operating charge.

The optimal ball diameter in a mill 333 The grinding efficiency of the narrow particle size fractions with ball charge of various diameters has been observed through the constant of milling rate k in the equation of the grinding kinetics law for the first order grinding R=R 0

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or
