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 from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the

The even wear allows for the new life potential of media rejected from ported SAG mills. The rejects are totally recyclable since the media retains their integrity for ongoing deployment in a secondary mill. Recycling to a ball mill as supplementary media or possibly as resale to other users provides additional value for our clients.
