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
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
The concept and theory to best understand a Ball Mill Circulating Load is shown here as an excerpt from Arthur and Ball mill circulating load PPT Circulating load
Nov 18, 2014· Circulating load calculate • E = Efficiency Screen % • R = Larger than mesh % • S = C.L. + new feed (t/h) • f = larger than mesh in feed % • C.L. = circulating load Slide 4 [2] 5. For being equal F and P,quantitative of fine material must be poured onto screen to pass equivalent weight of F from screen throe is not all this amount in the first load.

An industrial ball mill operating in closed–circuit with hydrocyclones was studied by five sampling surveys. The calculated results show that the circulating load larger than 3 has no
Ball Mill Circulating Load. 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 ratio and ball mill circuit performance makes the optimisation objective seem nebulous to both plant metallurgist and designer. Some of this confusion can be eliminated by taking a step back from the overwhelming detail of sharpness of separation curves, circulating load ratios, cyclone feed pressures, vortex and apex sizes etc
Calculate Circulating Load Ball Mill.

Circulating load control The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution water flow rate. Attempts to use this for density control were not successful. Because of the high magnetite concentration of the ore it was found that the actual density exceeded the required density,
Jan 01, 2013· A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.

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 is around 100-200%.
