index bond ball mill

ThisGrindability Test or Bond Ball Mill Work Index Procedureis used to determine theBond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ 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.

    ABond Ball MillWorkIndexmay also be used in the simulation and optimisation of existingmill(s) and the associated grinding circuit(s). Sample Requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for theBond Ball MillWorkIndextest feed.

    When F is the size in microns which 30 per cent of the new ball mill feed passes, P is the microns which 80 per cent of the last cycle sieve undersize product passes, and P1 is the opening in microns of the sieve size tested, then ball mill work index Wi is calculated from the following revised (1960) equation:

    The Bond Index conforming ball charge consists of:43 x 1.45” balls;67 x 1.17” balls;10 x 1” balls; 71 x 0.75” balls ; 94 x 0.61” balls; The optimum number of grinding balls is285. 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 20.125 grams. The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has well …
