• Effective mill power draw • Ball mill specific grinding rate • Ball mill grinding efficiency The circuit output is defined as the production rate of fines by the circuit. It is calculated from three values 1. The dry ore feed rate to the circuit th. 2. The fines in the circuit feed. 3. The fines in the circuit product.
predicted. Slurry pooling causes the power draw in AG and SAG mills to be lower than a mill without a slurry pool. This phenomenon results in overflow mills usually drawing less power than grate discharge mills that are operating without a slurry pool. This is because by definition overflow mills operate all of the time with a slurry pool.

Sep 01, 2016018332The increased mill charge load will lead to an increase in mill power draw. The onset point of overfilling an AGSAG mill can be indicated when the mill power draw exceeds the safe operation power threshold. In a ball mill, however, the mill power draw is dominated by ball media charge volume for a given mill rotational speed.
