Apr 01, 2013 1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).
Read MoreDouble helical feeders used in closed-circuit with classifiers; Spout feeders preferred when using a closed-circuit with classifying cyclones. Cyclones are typically installed above the mill and thus the cyclone underflow is fed to the mill by gravity. Discharge System.

Read MoreClosed Circuit Grinding VS Open Circuit Grinding. From a theoretical point of view, the ideal method of grinding would consist of a series of ball mills, each in closed circuit with a classifier and each so short that the ore in its passage through the mill would be struck only two or three times by the balls, any undersize produced being removed at once by the classifier ; in this way the ...

Read MoreAG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG ...

Read MoreINTRODUCTION The ball mill in closed circuit with cyclones is currently the most common grinding circuit in the mining industry, and has been so for over half a century. Due to its compact design, simple operation and low capital cost, cyclones have “squeezed out” other types of classifiers such as spiral and rake classifiers, which these ...
