Further DetailsThe 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 material
Further Details2 and 3 show the grinding product composition changes during the Bonds grinding tests performance using the test sieves 74 105 and 150 microns on limestone and andesite composite samples with
Further DetailsAccording to the Bond standard procedure the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250 circulating load Bond 1949 1952 1961 The test is performed on a raw material approximately weighing 10 kg which coarseness is 100 3327 mm
Further DetailsThis Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples These equation application methods are used to process 12″ ore samples in a Ball Mill using a standard ball charge Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory If you
Further DetailsThe Bond Index conforming ball charge consists of 43 x 145” balls 67 x 117” balls 10 x 1” balls 71 x 075” balls 94 x 061” balls The optimum number of grinding balls is 285 However the ball diameters vary due to wear Therefore the total ball number should be adjusted from time to time to ensure a total mass of 20125 grams The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has well
Further DetailsWork Index Ball Mill alluding to the grind ability list of Metals is utilized to demonstrate the granulating trouble of the material It is measured by a rule that to compute the work file ball plant in light of yield of every unrest of the factory after the material is ground to an adjusted state by the predetermined plan
Further DetailsBall mill was employed to conduct the grinding test of seven different samples Among all seven samples collected from the different faces of quarry Bond work index of limestone Face4A results less than 20kwht remaining 6 samples are marked as hard rock because of
Further Detailsball mill grindability The test mesh used was 100 mesh P 1416 The Bond work index W i was calculated from Equation 2 W i 445P 1 023 X Gbp 082 10P 80 05 05± 10F 80 2 Where F 80 is the size in µm at which 80 percent of the new feed to ball mill passes
Further DetailsThe Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test Its value constitutes ore characteristic and is used for industrial
