A Guide To Maximising Ball Mill Circuit Classification

2. from the ball mill discharge size distribution calculate the %+75 μ as: 100 – 26.5% = 73.5% +75 μ. 3. 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.
