The influence of the insertion depth of the vortex finder on efficiency, as summarized in Table 1 from various literature, shows that the maximum efficiency of the insertion depth of the vortex finder is closely related to the operating and structural parameters of the separator. For example, Hugi [9] designed a cyclone separator for a high-load circulating fluidized bed …

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).
