sag mill single stage copper mine
Power-based modelling of single-stage AG and SAG mill
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.

SAG Mill | Autogenous and Semi-Autogenous Mills |
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product ...
