A change in transfer size can be accommodated between 0.4 and 3.5 mm by an adjustment using the Bond ball mill work index. Starkey found that there was no observable difference in the energy consumption in a SAG mill or ball mill in this size range. This method of estimating mill power requirement has been successful in recent years. 3.4.6.
