Libya Grinding Rod Mill

Bond rod mill grindability test grinding solutions can carry out bond rod mill work index tests to determine the energy requirements for milling ore in a rod mill the test requires a minimum of 20kg of 125mm material closing screen sizes typically range from 475mm to 212m abrasion index test

Rod mills have an industrial yield that is less than that of a ball mill which explains the fact that balls have a much larger grinding surface than rods the power needed to operate a rod mill could exceed 30 of the power used in a ball mill

The grinding action of a rod mill is line contact as material travels from the feed end to the discharge end it is subjected to crushing forces inflicted by the grinding rods the rods both tumble in essentially a parallel alignment and also spin thus simulating the crushing and grinding action obtained from a series of roll crushers
