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.

where R, is the circulating load (in reverse circuit) expressed as percent of new feed, f is the percentage screen undersize material in the new income feed (F tons), and all other symbols have the same nomenclatures as mentioned before. If the new feed is free of screen undersize material, i.e., f = 0. the circulating load (R,,) will be:

Calculation of Circulating Load in a Classifier. A mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next …

This document presents an iterative algorithm for calculating circulating load in closed mineral processing circuits. The algorithm is based on analyzing flows through various unit operations and how they partition between streams. The key equations in the algorithm calculate circulating load at each iteration based on feed flows to unit operations and their partitioning efficiencies. The ...

How Much Circulating Load. In designing a closed-circuit crushing stage, the question of how much circulating load should be carried is a very important one. It not only has a direct bearing upon the capacity of the stage; it determines the amount of screening surface, and the elevating capacity necessary to handle the load in the circuit.
