Resumo

The trajectory and landing point of burden flow is determined by forced state. Based on comprehensive analysis of burden state forced in rotary chute, this paper presents a mathematical model of burden’s slippage process in rotary chute, and the related analysis are completed, mainly investigating the effect of Coriolis force (CF) and charge system on trajectory and landing point of burden flow. The results show that the velocity of burden departing from rotary chute decreases under the CF, and the landing point of burden trends the center of BF; the CF has observably effect with increase in length, angle of chute and the stock line.
