WEBApr 24, 2018 · The calculations indie 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 value for a n diameter mill, to a /1 L/D value for a throughput reduction to 10 percent of the original value. This high an L/D ratio is without precedent.
