A ball mill also known as pebble mill or tumbling mill isilling machine that consists ofallow cylinder containing balls mounted onetallic frame such that it can be rotated along its longitudinal axis. the balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size.
A ball mill isype of grinder used to grind or 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.all mill consists ofollow cylindrical shell rotating about its axis. the axis of the.
A rod mill is an ore grinding mechanism that usesumber of loose steel rods withinotating drum to provide its attrition or grinding action. an ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. although similar in operation,od mill is often more effective.
