Tubular Ball Mills ScienceDirect

Grate discharge mills give less excessive grinding compared to overflow mills and are best suited to grinds to 150250 μm. In Figure 7.2 C, the discharge opening is at the centre of the mill, while the feed is from both ends of the mill. The mills are therefore designated as a Centre Periphery Discharge mill.
