In general,ball millscan be operated either wet ordryand are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with theseball millsbecause they are very effective material handling devices.Ball millsare rated bypowerrather than capacity.
