It is therefore necessary for the cylinders to be of greater length than in ball mills. The number of balls used is also much larger, and, according to one view, the reduction of the ore is effected by grinding rather than by impact, as in ball mills, so that this constitutes another essential difference. The cylinders.

Ball Mills - 911 MetallurgistRod and Ball Mills not so much however as their size reduction actions are hidden in the tube (mill). As for Rod Mills, the image above best expresses what is going on inside. As rocks is feed into the mill, they are crushed (pinched) by the weight of its.Ball mill - WikipediaA 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.

the slip between the pebble charge and the relatively smooth silex or porcelain lining. The capacity of a pebble mill is considerably less than that of a ball mill of equivalent size or occupying approximately the same floor area. This differ- ence in capacity is due to the difference in the weights of the respective grinding.
