Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50 solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6 moisture. As such when the product is sticky rod mills are preferred over ball mills.

Rod mills are very similar to ball mills except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1.4 to 1.6.

The point where the mill becomes a centrifuge is called the quotCritical Speedquot and ball mills usually operate at 65 to 75 of the critical speed. Ball Mills are generally used to grind material 14 inch and finer down to the particle sie of 20 to 75 microns.

In ball milling the desired particle sie is achieved by controlling the time applied energy and the sie and density of the grinding media. The optimal milling occurs at a critical speed. Ball mills can operate in either a wet or dry state.
