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.

The classical grinding process for hard materials in the field of application of the glass and ceramic industry has always been dominated by the ball milling process. However, thanks to the availability of wear-resistant high-performance air separators, this dry grinding technology can now penetrate into much finer particle sizes of up to d 97 = 3.

Extended milling could achieve the hard mineral's desired grind, making it an energy-intensive process. The energy transfer between the particles reduces with the decrease in the impartation of kinetic energy to the particle using finer media. Ultrafine grinding mills were developed to get around these restrictions.
