Increasing the circulating load to 500% brings that value up to 2.6 times, for a further relative productivity increase of 30% (2.6/2.0 =1.30). And all this is achieved with the same ball mill power! The most efficient ball milling circuits require a high circulating load ratio. …

Circulating load calculation in grinding circuits - scielo.br

The adopted hydrocyclone flow split parameter was 83.74%. This indicates that 83.74% of the hydrocyclone feed returns to the mill as circulating load. Considering the new feed is equal to 482 t/h, the calculated circulating load was equal to 2,482.33 t/h, being necessary 177 iterations for the calculation.

Ball Mill Circulating Load - Mineral Processing & Metallurgy

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. Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or ...

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 ...
