Since about the late-1970s, stirred mills have entered into use in the mineral processing industry. Much work has focused on model developed for power, grinding and performance prediction. However, little effort is cited in the literature related to wear and particularly impeller wear. In this paper, the focus will be on examining how two pressure profile models might affect stirred mill impeller wear profiles specifically in the gravity induced stirred mill case. The investigation will start with a re-visit of a mechanistic impeller wear model for stirred mills which includes some indications on how impeller wear affects mill power. Subsequently a review of a few pressure profile models analysis will lead to exploring the effect of the pressure profile on impeller wear. The paper will close with a discussion on how the model could be used to illustrate the effect of wear on any impellor design. (C) 2016 Published by Elsevier Ltd.
