### Ball Mill Circulating Load - 911 Metallurgist

2015-10-9 The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load

The high circulating load means the slurry passes through the mill quickly, preventing the build-up of fines, and is rapidly sent to the cyclones for removal of the fines from the circuit. The result is a ball mill more filled with coarse (+150 mesh size) solids, and containing fewer fine (-150 mesh size) solids, both absorbing the power of the ...

First and foremost, as also explained in Bulletin No. 4, we always want a high circulating load ratio (CLR). Given the same CLR of 350%, see below how increasing the cyclone water usage affects the ratio of the water going back to the mill. This ratio is called the ‘bypass fraction’, and carries fine solids with it back into the ball mill.
