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 ...
