− The low vent volume through the bag filter is mainly due to very high pressure drop across the bag filter (180-200 mmWG). The actual flow measured is only 4% of the total separator air. • Mill was crash stopped for collection of chamber samples to evaluate size reduction progress in side the mill.

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 .

Calculate and Select Ball Mill Ball Size for Optimum Grinding

Calculate and Select Ball Mill Ball Size for Optimum Grinding. Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.
