• MATERIAL RETENTION TIME IN A BALL MILL &amp; VRM

Aug 11, 2010 Re: MATERIAL RETENTION TIME IN A BALL MILL &amp; 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

Third, in the typical ball mill, because coarse particles have a longer retention time, they have more “specific energy (kWh/t) applied to them” than do smaller particles, the study said. This means that “if a coarse particle is retained in the mill for a longer period of time, it is exposed to a larger amount of energy,” Bartholomew said
