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.

The mills were slowly turning cylinders with steel rods or balls inside. As the cylinders turned, the steel rods or balls collided and ground the ore even finer. Sorting - The slurry was carried to a classifier to separate out the large pieces which were sent back to the grinder. The small pieces continued to the concentration process.

In order to narrow the PSD, jet mills are equipped with a classifier. Only particle below a target size will be allowed to leave the mill, the others will be recirculated. Mills with size reduction media: Ball mills (dry) Ball mills are basically made of a drum partially filled with a grinding media, typically beads of ceramics or steel. ...
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...
In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.
