A comparison of SAG mill power models
the mill shell. The measured power is 3,190 kW at mill shell, so the model predicts high by 298 kW, or 9%. However, by substituting the recommended 5% allowance for a cone end instead of Austin's cone allowance results in a 148 kW of power generated in the cone, for a total of 3,113 kW power draw at the mill shell.
