Planetary ball mills are used wherever the highest degree of fineness is required. in addition to well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying.
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.
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
