Media to media contact for rods mills is linear rather than point to point (as with balls) and are much heavier. The larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded. This leads to a narrower size distribution and significantly less slime compared to ball mills.

Grinding Media Size Effect The ability to operate a mill with smaller-diameter grinding media greatly increases the mill's efficiency and can overall further increase the quality of product through finer grinding. However, smaller grinding beads are more prone to hydraulic packing due to their decrease in mass per bead.
