Rod mill rods wear - Grinding Classification Circuits ...

Sir, Rod length is 5.2 mtr.and sir I have a doubt that surface area of 100 mm rods is greater than 70 mm rods.so more material will be in contact with 100 mm rods than 70 mm.so I hope the wear rate in 100 mm rods is greater and for information the rod size is distributed in 25%,50% and 25% ratio.so I want to know the wear rate distribution among the rods.

Rod mills, how they function - Mine Engineer.Com

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
