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.
Nov 05, 2021 A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows material ball ratio of 0.7, ceramic ball medium size ratio (10 mm 15 mm 20 mm 325), stirring speed of 110 rpm, grinding concentration of 50%, and medium filling rate of 90%.
