    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

    Side effects of converting Ball Mill from Grate to

    We recently converted a grate discharge type ball mill (size 5.7X8.6m) to an Overflow type. Before conversion, the ball level was 26%, and we were able to obtain a grind of 90%+ passing 75mic at a throughput of 350t/h. After conversion it’s a nightmare to obtain 90%+ passing 75mic at the same thro

    Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the

    Dec 02, 2021 The ball mill is a traditional equipment used for ultra-fine grinding, and the product size can reach 20-40 microns. When the particle size of the product is required to be below 20 microns, the efficiency is low, the energy consumption is large, and the processing time is long. Stirring mill is developed on the basis of ball mill, mainly
