A simple one - ball mill w/ hydrocyclone. I observed that the most common methods applied are (1) use of water balance - taking samples of cyclone feed, cyclone underflow and cyclone overflow. They will get the %solids, then compute for dilution ratio - then finally, %circulating load. and (2) use of particle size distribution - the samples taken for %solids will be screened for PSD; then circulating load can also be …
Circulating Load Calculation FormulaHere 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 circulating load calculation in ball mill,grinding mill
ball mill – cyclo ne circuits have become an industry standard. Although mill capacity increases with circulating load, an optimum circulating load of 250% was established due to limitations in
Ball Mill Circulating Load Mineral Processing Metallurgy Oct 09, 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
The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. If your product size needed is 100% passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again
VRM and ball mill circulating load - Page 1 of 1 Sep 07, 2011· Re: VRM and ball mill circulating load. Mainly in USA, the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH.Normal range of cirulating load in a conventional close circuit
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
Oct 09, 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 of 100%, an additional stage of grinding and classification occurs. With high circulating loads, …
Feb 21, 2015 · 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 ratios …
Mar 20, 2016 · Circulating load = XT. Where X = B-A/A-C Classifier efficiency: 100 x B (A-C)/A (B-C) Compound Classification. To estimate the circulating loads in and the efficiency of each of the two classifiers operating in closed circuit with a ball mill: Original feed may be applied at the ball mill or the primary classifier. T—Tons of original feed
