Shear based power model. An alternative stirred mill power modelling method has been recently introduced in the literature (Radziszewski, 2013, Martins and Radziszewski, 2014). It is based on the assumption that any concentric stirred mill can be reduced to the analogy of a viscometer and therefore shear theory can be applied to model mill power.
