The high energy efficiency of stirred mills compared to ball mills is well understood. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century. Traditionally the higher energy efficiency was attributed to the difference between attrition.
What are the dimensions of the ball mill you are looking at 40 ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5 to 10 is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points. Beyond this, the situation may change.
