Optimization of mill performance by using - SciELO

Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration Figure 2 shows that there is no linear relation between

Rod mills, how they function - mine-engineer

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
