Rods in place weigh approximately 400 pounds per cu ft and balls in place approximately 300 pounds per cu ft Thus quantitatively less material can progress through the voids in the rod mill grinding media than in the ball mill and the path of the material is more confined...

Difference Between Closed Circuit And Open Circuit Ball Ball mill grinding circuit even though many ores require fine grinding for maximum recovery most ores liberate a large percentage of the minerals during the first pass through the grinding unit thus if the free minerals can be immediately removed from theDifference Between Closed Circuit

Ball Mill VS Rod Mill Xinhai For ball mill the grinding force of steel ball to ore is less than the impact because the contact area is small between balls and mineral Thus the throwing motion of ball can produce a large impact but it need a high rotate speed and has a higher power consumption

Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones This is generally followed by a cone crusher A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh 45 μm Instead of grinding the ore dry slurry is used as feed for rod or ball mills to avoid dusting

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
