For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

Calculation Of Ball Mill. 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.

More ### Mill Steel Charge Volume Calculation

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
