Ball Size Distribution In practice, at mill startup, instead of charging a single size of ball, usually a range of ball sizes is initially added.7.6 A ball mill is to produce a grind of 34 micron (Pso) product from a feed size of 200 microns at a rate of 1.5 t/h.

This therefore shows that should the material feed size continue to decrease, the smaller balls will perform better than the larger balls during milling, as was mentioned by Katubilwa et al.

For ball nose optimization (and in addition to tilting the tool), it is highly recommended to feed the tool in the direction of the incline and utilize a climb milling technique. To properly employ a ball nose end mill with a tool angle and gain the most optimal tool life and part finish , follow the 2-step process below.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Fig. 5 shows the variation of size class 1 (M1) with the milling time for the two feed size distributions. For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate.
