PEBBLE MILL GRINDING MEDIA Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between2 and 5 times the diameter. These mills are primarily used to …

    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.

    Only 4.5 kg of Sibelcopebblesare needed to grind 1000 kg of white ceramic body, compared to 7 to 20 kg of otherpebbles. For hard products (silica sand, feldspar) 6 to 9 kg of Sibelcopebblesare needed to grind 1000 kg.
