he methods and benefits of fine grinding ores

Media ball sizes, for example, range from about 20 mm for fine grinding to 150 mm for coarse grinding. Tumbling mills are typically employed in the mineral industry for primary grinding (i.e., stage immediately after crushing), in which particles between 5 and 250 mm are reduced in size to between 25 and 300 µm
