(PDF) Effect of circulating load and classification

The ball mill is the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed in ball mills.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 thatA guide to maximising ball mill circuit classification
