Abstract: In order to study the effect of gate’s angle on the pressure of vibrating feeder’s surface, in this paper, the feeding process of LDDF2330 vibrating feeder is simulated using EDEM, and parameters of gate’s angle is set to 80,70,60 and 50 degree at a constant of gate’s opening, respectively. The pressure of vibrating feeder’s surface was obtained and analysed for different gate’s opening with the same position and for different position with the same gate’s opening, respectively. Results show that the decrease of the gate’s angle results in the pressure of feeder vibrating bed surface decreases linearly and the position of the maximum pressure moves to the end of the vibrating feeder, respectively.
