2009-6-1 · It is difficult to compare the energy efficiency of the regrind ball mill with the IsaMill because of the different grind sizes, although it is obvious that the IsaMill consumes less energy than the ball mill. While the ball mill cyclone circuit on site was optimised for the coarse grind, there was no time to optimise the IsaMill for this duty.
