Input/output PSD data were taken from a closed-circuit industrial ball mill at the Twin Buttes operations of the ANAMAX Mining Company. The difference in open-circuit PSD is somewhat more pronounced at the longer retention time. The overall residence time distribution in the closed-circuit mill is totally dominated by the hydrocyclone recycle.
