Characteristics of open and closedcircuit grinding
15/04/2004· A closedcircuit grinding system, using a continuous vibration ball mill has been applied to the production of fine particles. However in most cases, the operational conditions are determined empirically. The reason for using empirical operational conditions is that it is difficult to estimate grinding performance. The grinding rate constant or the residence time in a continuous vibration ball mill is
