Improving stirred milling performance by selecting suitable media type with optimum bead sizing

This research intends to investigate the impact of media type and size on stirred mill performance. Stirred milling tests will be performed with ceramic medias of different mechanical properties and sizing. The energy-size reduction relationships under each test condition will be analyzed. The effect of media type and size on media wear rate will also be investigated as the media cost accounts for alarge portion of the total cost of stirred milling process. The overall benefits, including energy saving, media saving and product quality improvement, of selecting suitable media type and sizing for stirred milling applications will be evaluated with the case study on a copper mine operation at Canada.
