Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

The second approach to ball diameter calibration is the socalled absolute method. In absolute measurement, temperature is a first order error, that must be held at 68 °F (20 °C) exactly, or any variations must be compensated for. A micrometer or threaddriven measuring machine is an example of the absolute concept.
