  • Bond Work Index an overview | ScienceDirect Topics

    The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 310), a question arises as to whether this practice will alter the ball mill work index (BW i) of the materialThe standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass 127 mm, and size a representative sample The test then involves a series of batch grinds in a standard Bond rod mill A Bond rod mill is 0305m by 0610m, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as describedwhat is definition of bond milling work indexBond Tests Mining SGS * Bond F C, “Crushing Tests by Pressure and Impact”, Trans AIME, Vol 169, 1947, pp 5866 Bond Rod Mill Grindability Test The test determines the Bond Rod Mill Work Index which is used with Bond’s Third Theory of Comminutionbond mill work index definicion leuchtfeuerwerkat

  • BOND'S WORK INDEX: WHAT IT IS AND WHAT IT ISN'T

    The reason for this variation in ball mill work index is because the ore at Mt Milligan has an intrinsic exponent of –045 in the 100 µm to 200 µm size range, not the –050 exponent empirically measured by F Bond The work index increase between 100 µm and 76 µm is due to a porphyritic grain size that causes a spike in energybondmillworkindexdefinicion A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore It was developed by Fred Bond in 1952 and modified in 1961 JKMRC CO 2006 This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling for estimating the energy required for Get A Quote ContactBond Mill Work Index Definicion 007db5nl· bond mill work index definicion Bond Work Index an overview ScienceDirect Topics The Bond work index (Bond, 1960) is based on Bond’s law, which states that the energy consumed is proportional to the 15 power of particle size rather than the square of Rittinger’s law Accordingly, the energy consumed in reducing the particle size from x F to x p (both measured as 80% undersize) isbond mill work index definicion noclegibarlinekpl
