Improving Grinding Efficiency with the IsaMill™ UQ eSpace
The mill speed did not have an effect on grinding energy efficiency and it was found to be a reliable indicator of net mill power draw between 1400 and 2000 RPM, as shown in Figure 1. Less residence time was required to grind to a given target size as the mill speed was increased. Similarly, a linear relationship was a good fit for the net power draw when the media load was
