The rods crush the rock and as the charge passes through the mill it is reduced in size to between 2mm and 0.1mm. The mill can be fed from one end with the product removed from the other end or, alternatively, the mill can be fed from both ends with the discharge at the centre. The process can be wet or dry but is more commonly carried out wet.
