### Ball Charge and Grinding Efficiency - Grinding ...

The volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media wears down: add balls.

Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material)

### 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 approximated from the equation and calculation: % Steel Charge Loading in Mill = 113 – 126 H/ D

the tumbling charge. This energy is required to cause grinding of the material in the mill. The shape and dimensions of the lifters control the tumbling action of the media. The tumbling action is difficult to describe accurately but certain regions in the mill can be characterized in terms of the basic pattern of motion of material in the mill.

### Grinding Balls & Rods

For the first stage of grinding media will generally be in the 4″ to 2″ size (in some cases as high as 5″). In secondary finer grinding the initial charge will begin at around 3″ and in the case of balls will grade down to about ¾”. Extremely fine grinding will dictate the use of 1½” and smaller balls.
