A guide to maximising ball mill circuit classification system
Calculate the CSE as the average: (80.7 + 73.5) ÷ 2 = 77.1% + 75 μ. In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. This means that 77.1 per cent of the particles in the mill are 'coarse' and that 77.1 per cent of the mill power is being used 'effectively'.
