Rod mills are used for material up to 3 cm. Ball mills are used for fine grinding. They are often preceded by an AG, SAG or rod mill. Comminution AG/SAG mills accept a coarser feed than do rod/ball mills. Typical AG/SAG feed particle sizes range up to 30 cm (12 inches) which corresponds with the product size of primary crushing.

The ball mill no. 5 was also in good working condition in the case of pitting. However, after six months, wear and tear occurred in its pinion because of dust entering into the sets which were observed in visual inspection. These four ball mills (ball mill nos. 1, 2, 5, and 6) have classified under the slight pitting classification.
Overflow ball Mill. Product description. A rod mill is a mill in which the grinding body is a steel rod. The rod mill is generally a wet overflow type, which can be used as a first-stage open-circuit grinding.
