The model was successfully tested with RTD data of rod and ball mills available in literature. More recently, Hassanzadeh (2017) measured RTD in a ball mill operating at industrial scale. The circuit included a ball mill in closed circuit with hydrocyclones, where two feed flowrates were evaluated by means of NaCl as a tracer.

On the basis of the batch tests, continuous- grinding-circuit flowsheets were designed. The basic components of the continuous open-circuit and closed-circuit grinding plants were essentially the same as in the smaller scale tests. In the larger closed-circuit plant, however, a 6-inch-diameter, solid-bowl centrifuge was used as a classifier.
