Size of the milling balls should not be more than 34 orders of magnitude larger than your final grain size you want to achieve. Once you reach this grain size and you want finer powder you have to shift to smaller milling balls. Starting with very small milling balls right from the beginning is not recommended as they haven't

Chat Now### Ball mill Wikipedia

A ball mill is a type of grinder used to grind and 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. A ball mill consists of a hollow
