Apr 15, 2004 A closed-circuit 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.
Jul 03, 2012 Closed-circuit grinding, with high circulating loads, produces a closely sized end product and a high output per unit volume compared with open circuit grinding. Grate discharge mills usually take a coarser feed than overflow mills and are not required to grind so finely, the main reason being that with many small balls forming the charge the ...
