Predicting the specific energy of autogenous and semi

1. Introduction. It is generally recognised that the most accurate means for predicting the specific energy of an autogenous (AG)/semi-autogenous (SAG) mill circuit is to pilot the circuit using a 6 ′ 2 ′ mill (Mosher and Bigg 2001).However one of the major drawbacks of this approach is that a relatively large sample is required to do so.get price
