An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag ® ball mill on grinding and classifiion performance of a hybrid high pressure grinding roll (HPGR)/multicompartment ball mill cement grinding circuit. Mass balance of the circuit was done by JKSimMet Steady State ...

· 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. .

· The circulating load could be obtained by measuring the particle size distribution of the feed, the product and the reject, and by then using the Koulen method. (see this post ) The material M accumulated within the mill could be observed by measuring the level of the material within the mill, deducting the volume occupied by the balls and assuming a reasonable value for the material density.

Circulating Load Calculation Formula. 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).

increases with increased circulating load ratio, rapidly so at first and continuing to increase more gradually with higher circulating load ratio. The underlying cause of this relationship is revealed by comparing the ball mill feed and product size distributions from two circuits, one with low and one with a high circulating load ratio (Fig. 3 ...
