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.,

AMIT 135: Lesson 7 Ball Mills & Circuits - Mining Mill . Nuer, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†"V = 0.40 K√F

However, the total mill power consumption dropped 8% from an average of 7600 kW to 7000 kW. The mill work index dropped 10 percent from an average of 5.5 kW-hr/T to 5.0 kW-hr/T. Conclusions This represents a current view of the effects of grinding ball

Even the SAG ball charge needs to be adjusted based on the size and hardness of ore it’s working on. Too many grinding balls can prematurely wear out the grinding balls themselves. Operating a mine mill requires balancing a dynamic set of tradeoffs.

Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):-Modification of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency:
