Closed Circuit Ball Mill – Basics Revisited ScienceDirect. 1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to
Why Do We Need Such A High Recirculating Load On Our Ball Mill. The first step is to recognize the relationship between the ball mill circuit circulating load ratio (CLR) and the …
benefits of circulating load. Figure 2. Effect of circulating load and classification efficiency on milling circuit capacity [10] 2. Mathematical model ¨ The grinding kinetics in the ball mill follows first order grinding law which states that the rate of production of fines (D) is

The effect of circulating load and classification efficiency on the performance of ball mill circuits is compared to the effect on HPGR circuits. The fundamentals of grinding behavior are also ...
The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the ...

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 load is percentage of coarse return in relation to fines it can be calculated by : Coarse return TPH X 100 / Mill output range of cirulating load in a conventional close circuit ball mill is around 100200%.
The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
PDF Effect of circulating load and classification. CONCLUSION The circulating load and classification efficiency can have a significant effect on the performance of both closed ball mill and HPGR circuits This is a wellknown fact for ball mill circuits that has been recognised for almost 100 years For HPGR circuits the knowledge is more recent and is still being investigated
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 ...

Circulating Load Calculation Formula. 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 400 tons or more but this will be made clear by Fig 71
