2003年7月1日 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.

Overflow ball mill is also called overflow type ball mill. It is a kind of wet ball mill grinder, frequently used in the material refine grinding (finished material is lower than 0.2mm) or the second stage grinding. Overflow ball mills adopt the overflow principle to discharge the qualified material slurry higher than the discharge port naturally.
