  • the effect of circulating load on sag mill power

    The rock load in the mill essentially depends on ore characteristics and the circuit with classifiers whose circulating loads reach as high as 400-500%. grinding, flow-back can make a significant impact when the mills are operated in the load inside the mill increases and the mill draws more power.

    The effect of classification efficiency and circulating load was also investigated by Morrell (2008) who used Bond ball mill tests as the base line (Bond, 1962). Conventional tests (with 100% classifier efficiency) showed that the relative Bond Work Index was reduced by 8%, and hence the grinding efficiency was increased by 8%, when the circulating load was increased from 150% to 400%.

    2/1/2014· Mill grinding flux is related to “New feed” and “Return flux”. However, adjusting the circulating load will cause a series of chain reactions, for instance, reducing the circulating load will cause CKP mill vibration and add the output material flux of cement clinker, as shown in the Eq. . So the production of cement clinker is adjusted to achieve the best crushing rate of cement clinker.

  • Mill power draw models SAGMILLING.COM

    The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput. All models generally assume that a mill is fitted with "efficient" liners and that the grate design neither limits passage of pebbles (and pulp) nor permits re-circulation of pulp back into the mill.

    Calculating a grinding circuit’s circulating loads based on Screen Analysis of its slurries. Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios.

  • Circulating Load Calculation Formula

    Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load
