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 …
