With applications such as lime slaking or limestone grinding, smaller capacity ball mill systems are often required. In these instances, a cost effective option, when compared to larger trunnion mounted mills, is a roller mounted ball mill. This design uses heavy duty support rollers to drive the rotation of the mill shell directly.
