• ## Circulating Load Calculation Formula

Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating loadLoad Analysis of Rolls in a Rolling Mill: A Comparison of,the load is just transmitted from the rolls to the housing through the chocks. Therefore the roll load is P = 0.4 Vout × E × Atotal Following are the results of the calculation of the roll load for various passes of the material through the rolling mill on the basis of the output voltage obtained in High pressure grinding rolls (HPGR) applications in the,Feb 01, 2006· Circulating load ratios (separator reject/fresh feed) in HPGRs in Case Study 4 and 5 were 4.2 and 5, respectively. In air classifiers used in cement grinding circuits, an increase in separator feed tonnage causes an increase in the by-pass (Benzer et al., 2001). Therefore, better classification would provide a margin for further decrease in
