  • Addition of pebbles to a ball-mill to improve grinding

    Ball-mills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (7–25 mm) were used in various proportions with balls. The optimum proportion of pebbles by volume was found to be about 25 . Substantial savings in power and ball consumption were achieved with no loss in grinding capacity. However continuous pilot-plant tests were
