SAG Mill Grinding Circuit Design

 · AG/SAG throughput is defined by the unit power required to grind the ore to the closing size attained in the circuit. Very hard ores can severely constrain AG/SAG mill throughput. In such cases, the circuits can become capital inefficient (in terms of the size and number of primary milling units required) and can require more total power input relative to alternative comminution flowsheets.
