01/01/2005 Ball-Mill Circuit Operation. Very often in SAG circuits, the ball-mill circuit is neglected. In many operations where economics dictate that throughput is worth more economically than the required sacrifice in grind, the focus shifts to throughput so much that the available ball-mill power is not used to the fullest extent. Even in those operations where a firm grind target is not adhered to and attainable throughput governs the balance of the circuit
