Ballmills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (725 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.
