Operating data from the single stage SAG mill at Anglo American's El Soldado mine in Chile was evaluated and compared to four published power-based comminution models. Case studies from literature for other single stage SAG or AG mills were then evaluated in the same four models.
Comminution, particularly milling, is on average the largest consumer of energy in mining. Actual comminution circuits consist in most of the cases in coarse crushing, SAG milling, pebble crushing and secondary ball milling. In these circuits the SAG mill is the largest energy consumer.
