May 25, 2017The grinding in a batch mill, a grate discharge mill or trunnion overflow mill may be performed either “wet” or “dry”,but clearly in an “air-swept” mill the grinding must be carried out in the dry state. In “wet” grinding the material to be ground is fed to the mill in the form of a “pulp” containing, perhaps, 50% by weight of water.

Jul 18, 2008In dry grinding, material is transported through the mill by medium-high velocity air that is injected at the inlet or mill feed end. As the mill rotates, mineral critical size fines are brought to the ball charge surface and are suspended and liberated by the injected air velocity currents and swept out the exit port.
