measure CSE is a size distribution for the mill feed and discharge. For the typical reverse configuration ball mill circuit (Figure 1), this is achieved by taking a sample of cyclone underflow and a sample of ball mill discharge, and then running a screen analysis in the lab. For forward fed circuits (e.g. primary ball milling), a
