    The size of the milling media (typically 20:1 for ball:powder diameter) also influences size, morphology and microstructure of the powder. To produce fine powders, it is recommended to mill in several steps while reducing successively the milling media size, as one milling step usually induces a particle size reduction of about factor 10

    Size segregation of granular mixtures is one of the common types of segregation in a rotating drum. This phenomenon occurs in process equipment such as mixers, ball-mills and rotary-kilns. Here, we studied the segregation of bidisperse spherical glass-beads with size ratio ranging from 0.1 to 0.9 in a rotating drum by experiment and DEM modelling
