Abstract: Discrete element method (DEM) is currently being applied in the industries that involve the operation and process of particles. Aiming at the application of DEM in the industrial process analysis and product design, the characteristics of the DEM simulation were analyzed, the fields and its classification of industrial applications of DEM were introduced, and the problems and challenges that face the DEM application were discussed.
Key words: discrete element method(DEM); industrial application; simulation
