Dec 04 2020 The milling efficiency decreases with increased milling time as the particles become smaller. It is assumed to subside completely when the grain size reaches a critical value. This is a consequence of the force applied to the slurry as two milling balls approach one another causing a slurry flow away from the balls prior to collision as seen in Figure 3.
Effect of ball and feed particle size distribution on the . It was also observed from the experimental results that in order to increase the milling efficiency of a ball mill towards optimum production of material in the desired size class there is a need to correlate the ball size and the feed size distributions.
