This machine uses steel rods as the grinding media instead of balls, which are commonly used in ball mills. The rods grind the ore by tumbling within the mill, similar to the action of a rotating drum. Rod mills can be operated at lower speeds than other types of mills, making them ideal for fine and coarse grinding applications.
