AN ANALYSIS OF THE CLOSED-CIRCUIT GRINDING

teristics of a closed-circuit grinding system, chiefly based on computer simulation of grinding system, have already been published3'5'6'10-13'21-23*. From a practical point of view, however, none of them is sufficiently useful; none can be used as a sound basis for the selection of operating or design variables in any grinding system.
