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 Rod mills usually require greater operator attention
Working Principle of Rod Mill Rod mill works by relying on the moderative motion of peripheral rack wheel through electrical machine and reducer or the bradytelic synchronous electrical machine The barrel is driven by those motions so it is also called grinding rod mill There is proper ore grinding medium inside the barrel namely steel bar
A rotating drum causes friction and attrition between steel rods and ore particles citation needed But note that the term rod mill is also used as a synonym for a slitting mill which makes rods of iron or other metal Rod mills are less common than ball mills for grinding minerals
rod ball mill working process and rod ball mill working priciple To use the rod ball mill the material to be ground is loaded into the Neoprene barrel that contains grinding media As the barrel rotates the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours
