Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney 1937 defined the ball size as a function of the top size of the feed, i.e., d226V 0.40 K226F dB ball size cm F feed size

and with the decreased grain size, the necessary ball size also decreases Olejnik, 2010 2011. For each grain size there is an optimal ball size Trumic et. al., 2007. The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both

Some custom ball bearing feeders are able to feed multiple lines of parts and also multiple sizes. If you have multiple ball bearing sizes you would like to feed, then we would fabricate a system that has a quick changeover bowl. Each bowl corresponds to the required ball bearing size, and they are universal to 1 base drive.
