Circulating load ratio (CLR) is defined as the ratio of solids circulating through the ball mill to those through the entire circuit. It is important for grinding circuit efficiency, with optimal values of 350-400% for primary ball mills. The CLR equation compares solids exiting versus entering the ball mill. Higher CLR leads to more productive circuits through coarser slurry and faster ...
