Abstract: To solve the problem of excessive force and serious wear which impact on components of the transfer chute,the structural design parameters affecting the transshipment are obtained by using the trajectory and energy conversion relationship when the coal material is discharged.Using the discrete element analysis EDEM software , to simulate discharge status of the coal material in the linear transfer chute under the different discharge conveyor belts and the angle of the transfer chute.The results show that under the same working conditions, when the belt speed is lower than the rated maximum belt speed by about 25%, the average force value of the coal material to the funnel is the smallest and the force duration is the shortest. When the belt speed is higher than the rated maximum belt speed, The average force value of the funnel increases obviously; when the dip angle of the transfer chute is larger, the average force value of the coal material to the receiving conveyor belt is larger and the duration of the force is longer, and the conveyor belt has a deviation. The problem of missing material is more obvious.The conclusion will provide a reasonable basis and data support for the green development of mining equipment.
