Lacking both the data and tools for determining the …
It was found that the SGE efficiency increases by ~2.4% with increasing mill filling level from 60 to 72% v/v. This is most likely due to the improving residence time distribution in the mill. It was also found that a reduction in flowrate greatly improved the SGE efficiency and allowed the mill to run at slower speeds at the same power draw.
