Jul 20, 2017 When the test ball mill is run in open circuit the design feed rate is 27.42 tonneshour. Figure 4 compares the predicted size distributions from the open circuit ball mill with feed rates of 20.0, 27.62 and 35.0 tonneshour respectively. As might be expected, the larger the feed rate the coarser the grinding mill discharge product.
