The Understanding of Comminution and Classification and its Practical Application in Plant Design and Operation

For over 30 years the JKMRC has been conducting research aimed at improving the understanding of comminution and classification processes. The result of this research has been the development of a range of comminution and classification models which has been successfully applied in numerous optimization and design studies throughout the Australian Minerals Processing Industry. This paper reviews the current status of our understanding of the mechanisms which govern comminution and classification processes. Outlines of mathematical models of these processes are described together with examples of their application in design and optimization studies.
