Learn MoreThe reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the ore. The usual reduction ratio is about8.
Learn MoreTherefore, if minimum production of fines is desirable, it is logical that the heavy end of the 7:1 reduction should be handled in the latter machine. Generally, for such a case, the split would be about 3:1 to the standard machine, and 4:1 to the fine reduction crusher.Approximate Crusher Reduction Ratio.
Learn MoreWhen calculating rod mill power for a rod-milling-only application, use an inefficiency factor of 1.4 when the feed is to be prepared with open circuit crushing, and use 1.2 when the feed is to be prepared with closed circuit crushing. Themill diameter,low or high ratioof reduction,...

Learn MoreBond proposes an optimumreduction ratiofor rodmills[BON 61b, p. 545]. If the realratiodeviates, then W i must be multiplied by a correction coefficient (equation 26 in [ BON 61b , p. 545]). For a ballmill, if thereduction ratiobecomes less than 3 (targetgrindingof concentrates), the energy index W i must be multiplied by a given ...
Learn MoreAs the length to diameter ratio of the mill should be in the range of 1,2-1,5, the biggest rod mill will convert maximum1500 kW. Rod mills are used for primary grinding of materials with a top size of20-30 mm(somewhat higher for soft materials).

Learn MoreFig. 11 shows the results of thegrindingof a feed of various sizes at a sizereduction ratioof 45:1 using a 1 m diametermill. It can be seen that the optimum portion of the 50.8 mm balls decreases slightly as the value of N 1 increases for coarser feeds: 13.8 mm and 9.5 mm.
Learn MoreSizeReductionis mainly done through crushers andmills. Crushing andgrindingare the two primary comminution processes. Crushing is normally carried out on the "run-of-m ine" ore.
