## Scale up methodology for tumbling ball mill based on

Nov 01, 2010 This paper provides a method to scale-up horizontal tumbling ball mills, i.Lab Ball Mills.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). The impact energy of grinding balls was numerically analyzed, and the influence of drum dimensions and drum …
