Screw conveyor performance: comparison of discrete element ...

Screw conveyors are very effective for transporting dry particulates, giving good control over the throughput. Despite their apparent simplicity, the transportation action is very complex and designers have tended to rely heavily on empirical performance data. In this paper, we use the DEM to examine how variations of particle properties influence the performance of the screw conveyor.

2019-1-21  Discrete element method. DEM is a numerical technique used to simulate the movements of particles and interactions between neighbouring particles [].The basic idea of DEM is to divide the system into a number of particles, i.e. discrete elements (DEs), and the response of the whole system is described through the mechanical and kinetic states of each particle in the system.
