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 s on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell.
To improve the circuit performance at industrial scale, alternative ways of mill load measurement were investigated. detection of strain changes in the mill shell during mill rotation, by using a piezoelectric strain transducer, provided very interesting results, allowing evaluation of the weight of the mill charge and control of the powder ...
