Abstract:Abstract:Sintering shuttle distribution plays an important role in the uniform distribution along the width direction of sintering trolley. A threedimensional model was established according to the actual size of shuttle distributor of sintering machine in an iron and steel enterprise, and the shuttle distribution process with front baffle was simulated by EDEM software. The results show that when the angle of the front baffle of the shuttle distributor is 90°, the residence time of the shuttle distributor on both sides of the silo should be the same as possible. When the residence time is 7 s, the shape of the material surface is flat, and the particles mass fraction standard deviation in different areas is 0001. However, the difference of the mass fraction of the particles on both edges of the silo is still large, which may lead to the uneven distribution of materials. When the angle of the baffle in the front of the shuttle distributor is 60°, the particles mass fraction standard deviation in different regions is 0006, the flatness of the material surface is the highest, and the proportion of the smallest particle at both ends of the silo is the largest, which could effectively reduce the “edge airflow effect” and improve the sintering uniformity.
