The retention time, also called residence time, is the ratio (M/Q) [h] . The flowrate Q could be measured from the production P [tons/h] and the circulating load C and given by Q [tons/h] = C P [tons/h] . The circulating load could be obtained by measuring the particle size distribution of the feed, the product and the reject, and by then using ...

Why do ball mills have such high circulating loads? The ball mill grinds. The cyclones separate. But the pump neither grinds nor separates. So what is the purpose of having such a big pump to maintain high circulating loads in our grinding circuit?

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 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.
