Closed Circuit Grinding Henan Deya Machinery Co Ltd

Closedcircuit 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 grate open area plugs very quickly
