The Impact on Industrial Grinding Circuits of Changing and/or Controlling The Slurry Rheology - Plenary Address

This paper will summarize the trends resulting from the data generated in a large number of laboratory and industrial studies con- ducted by this author where various slurry rheology factors have been carefully changed and controlled. Factors such as percent sol- ids, addition and/or removal of fines, slurry mill filling level, specific material oriented breakage properties, chemical additions, etc. are discussed with a number of illustrating examples. This paper is specifically aimed at developing rheologically related operating guide- lines for plant engineers so that improved operating conditions can be selected.
