Grinding Circuit . The grinding circuit consists of a conventional SAB circuit with a 7.93m x 3.73 m 3,356 kW SAG mill and a 5.49 m x 8.84 m 4,474 kW ball mill in closed circuit with 6 hydrocyclones (4 operating and 2 on standby). SAG mill throughput typically ranges from 473 - 515 tph depending on the ore type being processed.
There is less chances of short circuit condition due to the gap between metal bond and workpiece. Power is supplied to the wheel through spindle either with the help of brushes or mercury coupling. The current flow between wheel and workpiece in ECG ranges from 50 to 3000 A. The machining gap voltage in ECG generally varies from 2 to 35 V. The ...
Abstract In 2009, the survey of Wei and Craig reported qualitatively on the benefits of process control systems in grinding and flotation. The present review of about twenty milling operations reports quantitatively on these benefits. Expert systems, model predictive controller, and fuzzy logic control systems, to name only the most used in the mining industry, have delivered superior ...
