    Aug 11, 2010 · Re: MATERIAL RETENTION TIME IN A BALL MILL & VRM. You could do that by measuring the material flowrate Q [tons/h] through the mill as well as the quantity M [tons] of material that accumulates within the mill. The retention time, also called residence time, is the ratio (M/Q) [h] . The flowrate Q could be measured from the production P [tons/h] and the circulating load C and given by Q …
