The approach proposed provides more accurate information for the reliable description of the grinding process and enables the scale-up of laboratory results to larger scale mills. Future work will focus on the evaluation and exploration of other important mill operating parameters, e.g. ball size and mill speed.

For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure …
