Closed circuit ball mill – Basics revisited - ScienceDirect

, to discuss the practical implications of circulating load and classification efficiency on the capacity of a ball mill in closed circuit with classifier(s). The reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250% circulating load and having 38% of fine material reporting to cyclone underflow, resulting in a classification efficiency of 50%.

Closed Circuit Grinding VS Open Circuit Grinding

Some advantages presented by grinding in closed circuit are that this arrangement usually results in higher mill capacity and lower power consumption per ton of product, it eliminates overgrinding by removing fines early and it avoids coarse material in the final ground product by returning this material to the mill.

Circulating Load Calculation Formula

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).

High recirculating loads in Ball Mill Circuits - Grinding ...

High circulating load is common in both reverse and direct ball mill grinding circuits. Why? Because the ball mill closed circuit is the last stage before separation. Cyclone overflow should be clean of coarse particles. About the big pump, it’s one of the most important equipment when you are going to increase your capacity.

Cement mill - Wikipedia

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
