Abstract：The movement of particles included such two processes as on the chute and in the free zone, and burden trajectory in the free zone was decided by the velocity at the chute tip. So it was very important to accurately describe the movement in the chute for exactly control of burden distribution. There were some mathematical models about the movement of particles, but most of mathematical models were on the basic of one-dimensional. Through monitoring of the burden trajectory on actual blast furnace, it was found that the movement of the particle wasn’t a line but a 3-D model. Through analyzing the force focus on a particle, a 3-D mathematical model was set up to calculate the impact point, to analyze the width of burden flow and research the effect of chute length, rotating velocity and titled holding on 3-D movement. It is found that the calculated result coincides well with the measured result.
