Only few investigations have been previously published on the scale-up of stirred ball mills. At constant recipe, a scale-up of stirred ball mills based on the passage number is possible when mills (both production and laboratory stirred ball mills) are of similar geometry and equal grinding media with equal filling ratios are used.

Planetary Ball Mill PM 200 Wet and nano-scale grinding with the PM 200. Wet grinding is used to obtain particle sizes below 5 µm, as small particles tend to get charged on their surfaces and agglomerate, which makes further grinding in dry mode difficult. By adding a liquid or dispersant the particles can be kept separated.

This paper provides a method to scale-up horizontal tumbling ball mills, i.e. to determine the dimensions of the rotating drum and the drum rotational speed. In order to develop the scale-up methodology, the motion of grinding balls in tumbling ball mills with different drum diameters was calculated using the discrete element method (DEM).
