f.c. bond bico ball mill the f.c. bond ball mill is a small universal laboratory mill used in calculating the grindability of all ores. grindability is the number of net grams of screen undersize produced per revolution. this ball mill can be used continuously or it can be used for any number of revolutions, according to the type of grind desired.,determination and scale-up of the milling parameters of a,an experimental laboratory scale ball mill available at the university of lubumbashi was used in this research work. the ball mill measured 0.305 m in diameter and 0.127 in length. it was driven by an asynchronous motor rated with power close to 10 kw. a schematic of the experimental laboratory ball mill used is shown in fig. 3.
it can be observed that for a ball mill circuit closed with cyclones, circuit relative capacity is not expected to increase significantly by increasing circulating load from 250% to 600%. this is because of the reduction in classification efficiency from 50% to 30% as calculated by eq. (11). compared to the ''reference point'', a ball mill,(pdf) design and fabrication of mini ball mill,a comparative study was carried out for an alloy of al 50 (ni 75 mo 25) 50 processed by two different high energy ball mills. a spex and simoloyer mill were used.
