Ball Mill Circulating Load Mineral Processing &
09/10/2015· The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load
Circulating Load Calculation Formula
21/02/2015· If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70). In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently

Circulating load SlideShare
Bond work index is changed with the change in the test sieve size and circulating load. This must be taken into account when energy consumption is calculated according to the Bond formula. unit energy cost extra increased as circulating load decreased from 250%. However, unit energy cost decreased as circulating most suitable circulating load for amorphous silica used experiments is 250% because mill
(PDF) Effect of circulating load and classification
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%.
