To compare the material transport characteristics of rod mills with those of ball mills, identical experiments were performed with the mill charged with Lucite balls. Material transport characteristics were delineated using the tracer impulse-response technique frequently employed in fluid flow studies.

Thus, a heavily recycled system becomes in effect a backmixed system and local material transport (through the mill) is insignificant in shaping the overall R-T-D. The PSD models illustrated in this paper indicate that one technique for modeling the material flow (size-dependent R-T-D) is to assume classified discharge from a one-stage mixed particle slurry.
