The structure of overflow type ball mill is basically the same as lattice type ball mill; their difference only lies in the discharging end of barrel body has no discharging grid. Furthermore, the anti spiral impeller is arranged on the surface of the hollow shaft neck bush, which can return the overflow ball in pulp and the coarse ore to the mill. The finished product of overflow ball mill is discharged through the free overflow hollow shaft neck. Therefore, the pulp barrel body level must be higher than the lowest row of mine shaft neck level, which is sometimes referred to as high slurry surface grinding mill.
