Ball Mill Fractional Filling

The tests covered a range of slurry concentrations from 30 to 55 vol solid and fractional interstitial bed filling u from 0to 1, at a fixed ball load 30 of mill volume and 70 of critical speed, using batch grinding of a feed of 30 mesh 0mm quartz a fixed slurry concentration, the net mill power versus u went through a maximum, and both the optimum value of u for.
