Get PriceEmail contact01/11/2009 Due to the variation of ball load from 10.8% to 15% in the tests, the greatest difference of ball load volume at the same fill level is 4.2%, which is a relatively minor difference and thus results in a slight change of angular position of the maximum vibration point at the same fill level in three tests. However, the changes of ball load at the same fill level in different tests can lead to notable differences in the vibration of the mill shell. Since the variation of ball

As defined, this value should never exceed 100%, but in some cases – particularly in Grate Discharge Mills – it could be lower than 100%. Note that this interstitial slurry does not include the overfilling slurry derived from the difference between the Charge and Ball Filling.
