Addition of pebbles to a ball-mill to improve grinding efficiency .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.Ball Charge and Grinding Efficiency - Grinding & Classification .Apr 4, 2017 . With very low ball charge (less than 20 %) and low slurry density power draw will increase because of increasing toe angle and also more lifting. Also with low ball charge slurry pool will reduce grinding efficiency. Beside lower ball charge will increase P80 of ball mill because of less number of impacts but.
