· Ensure that the lime shutoff valve to the ball mill is open. Start ball mill lime timer. The lime control valve should be pulsing open for 3 seconds every 30 seconds (after calibration of all lime timers). Open sodium cyanide shut off valve until fully open. Normal Ball Mill and Grinding Circuit Operation.
Circuit Operation. Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12 ).
Closed Circuit Dry Grinding Ball Mill. Ball Mills Solid, reliable and durable . The Christian Pfeiffer Ball Mills are robust, durable and extremely reliable in operation. By using ball mills in closed circuit with a separator, their efficiency can be increased even further. Available as an end discharge mill, airflow mill or wet mill.
