Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding ...

While it is possible, if not advisable, to allow pieces of 2″ or even 3″ size in a ball mill, it is essential that the feed of a rod mill should be no larger than 1-in. and preferably smaller. For the same reason the ore must be friable ; rods cannot compete with balls in grinding hard or tough material.
