    Mill HP is proportional to the 2.6 power of the internal mill diameter (inside shell liners) provided the percentage of critical speed is the same. The table right gives the 2.6 power of most frequently used mill diameters. For practical purposes HP is proportional to speed. This applies to a specific mill over small changes in speed.
