CASE NOTE ACS1000 variable speed drive increases output and performance of SAG mill The LaRonde mine in Canada is Agnico-Eagle's flagship operation producing about 260,000 ounces of gold annually. In order to run the motor and the SAG mill at the required load output the existing drive was replaced with ABB's ACS1000 variable speed drive.

Typical types of mill used in ore beneficiation are autogenous (AG) and semi-autogenous (SAG) mills together with ball mills to, for example, obtain particle sizes smaller than 100 µm. One process variation that has become increasingly established in recent years is the combination of AG or SAG mill with a ball mill and a downstream agitated ...
