A different mechanism leads to the formation of rod-like aggregates close to pH 2.0. Hydrolysis of the proteins has been observed at these conditions, but it is as yet not clear to what extent hydrolysis is a necessary condition for the formation of rod-like aggregates. β-lg and WPI aggregates have been found to be useful for food applications.

Rod Mills - Mineral Processing & Metallurgy

The following cost advantages should be considered when evaluating rod mill grinding: Rod Mills use low cost grinding media. Less power is required since grinding rods are not cascaded and operate at lower peripheral speeds. Higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media.
