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.
Grinding Media - Growth Steel
Optimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput. Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimising operational cost.
