Because the rods are rolled rather than cascaded, rod mills run at a slower pace than ball mills. Rod mills require less steel than ball mills for a comparable grind because the media and ore make better contact at a reduced speed. Broken and damaged rods should be removed in order to keep the rod charge in excellent operating order. Rod mills ...
