The grinding media impart the forces required for size reduction and determine the category of tumbling mills: autogenous, rod mills and ball mills. Autogenous and semi-autogenous mills are used in primary grinding whilst rod and ball mills are used in secondary grinding, with the ball mills being the most commonly used.

How do you decide between using a ball mill or a rod mill? Many investigators have attributed the selective grinding of rods to line contact. Other things should be considered. In the two pairs of tests shown in table 12 the relative deportment of large balls and small rods in batch wet grinding is shown. The two loads had the same volume.

The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%.

Rod Mills, on the other hand, use rods instead of balls to grind materials. These rods have a larger surface area than balls and provide a more uniform product size when used in conjunction with screens or classifiers. Tower Mills operate similarly to ball mills but use vertical cylindrical chambers instead of horizontal ones.
