The grinding medium in the mill repeatedly impacts and grinds the material by virtue of the kinetic energy obtained when the mill rotates. The crushed material is discharged into the suction tank through the tail of the ball mill, and then transported to the classifier for classification by negative pressure.

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.
