Jan 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 sace in grind, the focus shifts to throughput so much that the available ball-mill power is not used to the fullest extent.

(SAG) mill, ball mill, and crusher. A ball mill is a slightly inclined, horizon-tal rotating cylinder, partially filled with ceramic balls, flint pebbles or stainless steel balls, that grinds material to the necessary fineness by friction and im-pact with tumbling balls (Fig. 2). An example of an industry-standard comminution circuit providing high

Conventional mining process circuits use both Semi-Autogenous Grinding (SAG) and Ball mills. It is very common that the SAG mills are operated with adjustable frequency drives (AFDs) and the Ball mills are operated at fixed speed [1]. Recently, however, adjustability of Ball mill speed has been given more consideration. Also, to maximize throughput, the Ball mills are sized to be operated at ...
