Ore discharge refers to the rod mill that the ore is discharged by the ore pulp itself. Unlike the overflow ball mill, which has no neck of hollow shaft at the discharge port, instead, it has a wide aperture trumpet overflow port in the center of discharge port (Fig. 1). In order to avoid pulp splashing and steel rod sliding out of the mill ...

Discharge grates play an important role in determining the performance of autogenous, semi-autogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp lifters.
