In tumbling mills the mill shell is rotated and motion is imparted to the charge via the mill shell. The grinding medium may be steel rods, balls, or rock itself. Tumbling mills are typically employed in the mineral industry for coarse-grinding processes, in which particles between 5 and 250 mm are reduced in size to between 40 and 300 m.
To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation. To produce fines (or filler) from mineral fractions by increasing the specific surface. Grinding takes place in more open space which makes the retention time longer and adjustable compared to crushers.
