    The constant K 2 is also dependent on ore type and ranged from 1.4 to 1.5. A regression of Magdalinovic s data including the feed 80 passing size gives an average value of 1.485 for K 2.If we extend this relationship to any sample of screened material then this gives an approximate estimate of the 80 passing size as 67.3 of the top size.

  • How to Reduce Ball Mill Overload Risk

    The calculations indicate that in order to obtain overload with smaller mills at a constant circulating load the L/D ratios would have to increase progressively from the initial 1.2/1 value for a 5.5 n diameter mill to a 6.8/1 L/D value for a throughput reduction to 10 percent of the original value. This high an L/D ratio is without precedent.
