Modifying blasting practices to achieve a more suitable mill feed size which varies according to the crushing/grinding circuit can achieve up to a 30% increase in throughput. Following an initial benchmarking of an operations practices,

Factors Affecting Ball Mill Grinding Efficiency
a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for high reduction ratios, and

Ball Charge and Grinding Efficiency Grinding
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.

Mills usually operate in the range 65 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating.

Dry batch milling tests were performed in a laboratory scale ball mill measuring 30.2 by 28.2 cm. The mill specifications are given in Table 1. A constant ball load of 20% was maintained in all the tests with a ratio of 0.5 for binary and 0.33 for trinary ball mix. Table 1. Specifications of the mill.
