circulating load calculation in closed circuit ball mill
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).

Calculating Power Draw When Sizing Ball Mills: Arabinda
This document discusses factors to consider when sizing ball mills for mineral processing. It notes that recirculating load has no direct effect on power calculations for mills, although it will impact mill capacity. Increasing fresh feed rate does increase calculated power needs. Experts in the comments discuss that mill sizing should consider the entire grinding circuit, not just the mill ...
