Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced Various classifiers, such as screens, spiralLarge to mediumsized ball mills are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion) A rock tumbler functions on the same principle Ball mills are also used in pyrotechnics and the manufacture of black powder, but cannot be used in the preparation of someBall mill WikipediaVery large tonnages can be ground with these devices because they are very effective material handling devices The feed can be dry, with less than 3% moisture to minimize ball coating, or a slurry can be used containing 20% to 40% water by weight Ball mills are employed in either primary or secondary grinding applications In primary applications, they receive their feed from crushers, andSmall Ball Mills for Sale 911Metallurgist
