The goal of this paper was to propose and apply a simplified stirred mill model that could then be used to assess the stirred mill design space. To this end, a stirred mill model was proposed based on the assumption that the main if not only mechanism of ore breakage is through shear. The basis of this model is the fluid mechanics definition of shear stress which led to defining a stirred mill ...
