Regrind Mills: Challenges of Scaleup Abstract
RPM. The mill configuration and operation discs, disc speed; media– size, media type and media filling; and mill discharge classifier – are all very similar to the full scale operation. Therefore the feed particles "see" the same grinding and classification mechanisms as they do at full scale. Because the grinding media

COARSE GRINDING ON A ISAMILL?
Figure 1 illustrates the grinding mechanism within the IsaMill™. The IsaMill™ typically operates around 70% media filling volume of ceramic media. As the shaft rotates, the grinding discs agitate the media via the kidneys and the surface of the discs, such that it is centrifuged out along the face of the discs towards the shell liner.

Prediction of the disc wear in a model IsaMill and its effect …
Understanding wear and its effect would provide a useful insight for process optimisation. This paper combines the discrete element method (DEM) with a commonly used wear model to predict the wear pattern of stirring discs in a model IsaMill. The results show that wear is more severe at the outer face of discs and the lifting side of holes.
