Ball Mill Modelling Using Cfd

modelling a wide range of industrial applications particularly in milling Early work on ball mills by Mishra and Rajamani 1992 1994 has been followed by Cleary 1998b 2001b Similarly SAG mills were modelled by Rajamani and Mishra 1996 and subsequently by Cleary 2001a Until fairly recently mill modelling was performed in two dimensions
