Differently from ball mills, in the vertical roller mill the separator is inside the machine and only fine and rejected materials can be collected. The feed is calculated assuming a reasonable circulating load in the range of 8 -12. The graph (Figure 2) illustrates the two Tromp Curves achieved with MA.G.A./VM 10 and without any grinding additive.
