How to Operate a Grinding Circuit

Thinner and finer overflow; higher circulating load. Decrease: Thicker and coarser overflow; less circulating load. In addition a few mills use a baffle board across the classifier pool. Shifting the baffle toward the tail end throws out a coarser overflow; moving it ahead makes the overflow finer and pulls out more sand into the circulating load.
