Increase Plant Throughput by Mill Expansion. Shortly after start up it was apparent that it would be difficult to obtain the plant design throughput The ore sample that had been used for grinding test work was found to be much softer than that of the orebody in depth This had led the designers to design without a crushing stage and to designate the primary semi …
