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.
