Rod Mill an overview | ScienceDirect Topics

Rod Mill Rod mills are charged initially with a selection of rods of assorted diameters, the proportion of each size being calculated to approximate to a seasoned or equilibrium charge From: Wills' Mineral Processing Technology (Eighth Edition), 2016 Related terms: Ball Mills; Mechanical Alloying; Amorphous Phase; Mechanical DisorderingRod mills are very similar to ball mills, except they use long rods for grinding media 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 14 to 16 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) Grinding action is by line contact between the rodsRod mills, how they function Mine OR Select a Topic that Interests you Use Add Reply = to Reply/Participate in a Topic/Discussion (most frequent) Using Add Reply allows you to Attach Images or PDF files and provide a more complete input Use Add Comment = to comment on someone else’s Reply in an already active Topic/Discussion ←Selection, breakage and appearance function equation

31052016· In standard rodmilling it will be found that rods spread apart at the feed end in the amount of the maximum size of feed entering the mill In the center peripheral discharge mill the rods are spread at both ends and parallel throughout the length of the mill This feature results in more space between the rods and thereby lessens the amount of fines produced Furthermore, fines are also diminished because the material moves rapidly through the mill01081992· Finding the breakage and selection functions for a continuous mill has usu ally been performed as a two stage process, where the breakage function is found first using batch tests, and the selection function is then found using data from the continuous mill The reason for this approach is that estimating both functions using data from the continuous mill have generally been re garded asEstimating the breakage and selection functions for aFactors that must be considered when selecting milling tools include the type of material being machined, the shapes of internal and external profiles, the amount of stock to be removed along internal and external profiles, the desired finish of the part surfaces, and the capabilities ofIntroduction to Selecting Milling Tools
