Abstract: The mathematical model based on the discrete element method was proposed to investigate the behaviors of solid particulate motion from particle-scale view, the burden flow pattern and the distribution of interaction force-chains between the particles. The results showed that the force networks of meso-scale structure in blast furnace are obtained by establishing the discrete element method (DEM) model. The strong force networks exist in the center of hearth and support the weight of charge column. The most strong chains zone corresponds to the deadman zone of blast furnace. The flow pattern of burden particles has four regions: deadman zone, piston flow zone, quasi-static slip flow zone and channel flow zone. The channel flow zone corresponds to the weakest force chain.
