Discharge grates play an important role in determining the performance of autogenous, semiautogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate designopen area and position of apertures, as well as the performance of the pulp lifters.
A x Outotec grate discharge ball mill with an installed power of and Turbo Pulp Lifters is operated in closed circuit with 250mm cyclones to provide a 45 m product to flotation. The primary mill was initially commissioned as an Autogenous Grinding (AG) mill.
