Indeed, according to Boulvin et al. [44], experimental data from a grinding circuit show that mill throughput impacts the separating curve. A recent experimental study on parameters affecting the VRM performance shows a correlation between product fineness and dynamic separator speed, mill throughput, and the rollers hydraulic pressure applied to the grinding table of the VRM [45].
