Mill Power Draw Model Bibliography

Mill power draw models are used to predict the usable power draw that a particular mill will generate. The three SAG mill models are benchmarked and reviewed in:

  1. Doll, A.G., A comparison of SAG mill power models, Procemin 2013 [1]

Austin SAG Model

The Austin SAG model was published in:

  1. Austin, L.G., A mill power equation for SAG mills, Minerals & Metallurgical Processing; Society for Mining, Metallurgy & Exploration, February 1990. [2]

Morrell Models

The Morrell models for SAG and ball milling are all derived from the same reference and differ in some default parameter values and in the geometry of the mill charge (grate versus overflow discharge).

Loveday/Barratt Model

Loveday produced a largely empirical model using a "Power Number" parameter:

Barratt developed a chart of "Power Numbers" for SAG mills that was published in:
