Page 1 Page 2 INTRODUCTION SAGinto circuit design at times, as it is often a consequence of the use of gravity classification devices (cyclones, screw classifiers) rather than a result of the comminution equipment selected Heavier minerals are generally classified at a finer cut point than lighter varieties, which can result in over-grinding Primary Circuit Selection Matrix...know more

Grinding CircuitsInitially faced with a blend of primary and oxide ore, the circuit achieved in excess of 320tph until the oxide was depleted, leaving only the much harder primary feed The 20MW semi-autogenous grinding (SAG) mill and 37MW ball mill was assisted by a 150kW pebble crusher, but the power limitation of the SAG mill resulted in a drop in throughput...know more

TransformerA transformer is a passive electrical device that transfers electrical energy between two or more circuitsA varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force across a second coil wound around the same core Electrical energy can be transferred between the two coils, without a metallic connection between the ....know more
