Design considerations for large diameter ball mills ...
01-04-1988 Such a correlation is needed for the scale-up design of large ball mills. In order to accomplish such a correlation we analyzed not only our own RTD data, but also the data of others. The data includes mill diameters ranging from 0.4 to 5.5 m (1.3 to 15 ft) and lengths ranging from 0.4 to 9.8 m (1.3 to 32 ft) with ball sizes ranging from 38.1 to 76.2 mm (1.5 to 3.0 inches).
