Abstract A comprehensive automatic control system has been developed and implemented for the two-stage grinding circuit at the Paddy's Flat gold plant of Dominion Mining Ltd at Meekatharra in Western Australia. The circuit comprises a SAG mill in closed circuit with a pebble crusher, followed by a ball mill - cyclone secondary circuit. The control system was configured on a …

Open Circuit Rod Mill-Closed Circuit Ball Mill. This configuration has proven in the past to be a most reliable system due to the fact that rod mills are not particularly susceptible to variations in feed size. However, the necessity to procure grinding rods may limit the usefulness of this approach in certain locations.
