circulating load calculation for raw mill

VRM and ball mill circulating load

Sep 07, 2011Re: 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%.

Feb 21, 2015Feb 21, 2015Cytec Handbook. Why have a large circulation load:. 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).

QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE

By using the obtained constant k, it is possible to calculate how long it takes for grinding, i.e. required mill revolutions to grind material when a steady state is achieved (circulating load 250%). In cases where equilibrium state is achieved with 250% circulating load: 𝑅0= 2,5 3,5 + 3,5 and 𝑅=2,5 3,5 (4)
