How to Calculate Work Efficiency Sciencing
The formula to calculate work efficiency is the ratio of output to input expressed as a percentage. For a machine, you can determine the work put into the machine depending on how the machine works. You can generally calculate work by multiplying the force times distance for the motion.

Stirred Mills Ultrafine Grinding ScienceDirect
Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.
