Simulation of particle flow in a bell-less type charging system of a blast furnace using the discrete element method

- A 3D DEM model was developed to analyze particle flow and segregation during charging process.
- Burden falling trajectories were obtained using laser grid method.
- Radial segregation index was used to quantify size segregation in the heap.
- Segregation of small and large particles is usually more obvious than that of medium sized ones.
