In this study, the influence of cone-in-cone insert parameters on silo discharge behavior was investigated using DEM simulations. The simulation results showed that the insert angle beta and the height from the silo port H1 significantly affected the flow pattern. To achieve mass flow, appropriate combinations of H1, H2, and D2 should be selected when beta is greater than 135 degrees. Adding an insert with beta greater than 130 degrees resulted in evenly distributed normal pressure along the silo wall and reduced wear.
During silo unloading, the reliability of the silo can be improved by adding inserts with appropriate parameters to improve the flow pattern. In this study, DEM was used to study the influence of the cone-in-cone insert pa-rameters on the silo discharge behaviour. The contact parameters were measured through a series of experi-ments, and the DEM model was established and verified. Furthermore, the silo unloading process with different insert parameter combinations was simulated, and the flow patterns were characterized by the Mass flow index (MFI). The simulation results revealed that the insert angle beta and the height from the silo port H1 significantly affect the flow pattern. To realize the mass flow, H1, H2 and D2 should be reasonably selected under the beta > 135 degrees. After adding an insert with the beta > 130 degrees, the normal pressure along the silo wall was evenly distributed, and there was less wear.
