Development of particle flow simulator in charging process of blast furnace by discrete element method

DEM Analysis of Particle Trajectory in Circumferential Direction at Bell-less Top

“…Recently, DEM 8) has been developed for the powerful simulation tool for analyzing particle behavior, and applied to simulate and visualize particle flow in the blast furnace top charging system. [9][10][11][12][13][14] The authors have already reported its high potential to be an optimizing tool for burden distribution control. Therefore, this simulation can clarify the circumferential imbalance of the particle trajectory.…”

DEM Simulation of Burden Distribution in the Upper Part of COREX Shaft Furnace

“…In the ironmaking field, plenty of papers about the burden distribution found that the simulation results basing on DEM coincided well with the experiments and industrial operation. 14,15,[21][22][23][24][25][26] In present work, a three dimensional model of charging system in COREX shaft furnace is established basing on DEM. After validated by industrial experiments, this model is used to investigate the effects of some factors on the burden profiles and size distribution along radius, such as distributor angle, rotating speed and length, and the stock line.…”

Effect of the Main Feeding Belt Position on Burden Distribution during the Charging Process of Bell-less Top Blast Furnace with Two Parallel Hoppers

“…Mio et al established a full model of the charging process in the bell-less top blast furnace and analyzed the particle segregation in spatiallydistributed and temporal-distributed in each process. 20) The study showed that the larger particles tend to be discharged last, because they are near the side wall in the surge hopper or the parallel ones. Ketterhagen et al studied the particle flow mode with hopper and delineated the mass-flow and funnel-flow behavior based on the hopper wall angle.…”
