Effect of ball size and powder loading on the …
In this figure, the positive influence of the smaller ball size on the milling efficiency is drawn by an arbitrary negative slope with ball size rather than the dependency of d −3, because the dependency of d −3 is valid only in a stationary state of ball packing while the actual ball milling is a dynamic event taking place under the presence of the powder slurry existing between the balls. Actually the …

Ball mill - Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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. A ball mill consists of a hollow cylindrical shell rotati
