This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.
Zero Order Production of Fines in Grinding
14-07-2018· Besides the dry ball mill grinding operation, the zero order production phenomenon has been observed for wet ball mill and dry and wet rod mill grinding operations also.
