Key words: ball mill; circulating load; classification; efficiency; model 1 Introduction Closed ball mill – cyclone circuits are industry standard and it is recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding The individual effect of circulating load and classification efficiency is difficult to quantify in18/11/2014· Slide 3 circulating load ratio : As the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit Circulating load circulating load ratio New feed circulating load ratio [8] 4Circulating load SlideShare07/09/2011· Re: VRM and ball mill circulating load Mainly in USA , the term circulating load is more often used than the circulation factorCirculating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPHNormal range of cirulating load in a conventional close circuit ball mill is around 100200%VRM and ball mill circulating load Page 1 of 1

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, and focusing on the purpose orCirculating Load Of A Ball Mill circulating load of a ball mill in fiji In practice circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent It may appear strange at first sight that the circulating load between a mill and classifier producing for example 100 tons of finished product per day can be as much as 400Circulating Load Of A Ball Mill vaikuendokrinologijaltCirculating load calculation in closed circuit ball mill s circulating load calculation made in a mill –this plant includes one SAG mill in a closed circuit with a vibrating screen and one ball mill with a size classification necessary to calculate the proportion of each mill's energy of ball mill's circulating load was obtained, 149 , which isCirculating Load Calculation FormulaBall Mill Circulating Load From Screen Anlysis
