A set of experimental test work has been carried out in a continuous pilot ball mill of 0.41m X 0.56 m (diameter X length) at different mill speeds, percent solids and discharge mechanism. The results of study on material flow through a grate discharge tumbling mill verses an overflow tumbling mill are presented to emphasize the effect of discharge flow mechanism.

If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.
