  • A three-dimensional analysis of media motion and

    The analysis was based on the three-dimensional filming of the motion of balls in a model rotary mill (Powell and Nurick, 1996b) These definitions are considered by the authors to be useful and consistent, and have been the basis for the ongoing analysis of the motion of grinding media in mills.

  • Analysis of Mill Performance of Industrial Scale Ball

    The simulation of grinding process of an industrial scale ball mill was carried out using the discrete element method (DEM) Combining the information from DEM simulation and theoretical or empirical models, the related parameter values of mill performance are obtained, which have some reference value to the design, optimization and selection of ball mills.
