Abstract:In order to study the influence of feeding mode on the performance of single screw feeding, based on screw feeding theory and using EDEM software, a screw feeding model with discharging device was established. The screw feeding process of soybean particles with 5.5 mm diameter was simulated under 60 r/min and 120 r/min, respectively. The total energy loss in the screw feeder at the two speeds and the difference of the feeding quantity were compared, and the trajectory of the particle group movement was analyzed. Numerical analysis shows that the mechanism has low initial energy consumption, small feeding fluctuation and less relative action between particles in dynamic feeding mode. Meanwhile, the mechanism has high initial energy consumption, big feeding fluctuation and more relative action between particles in static feeding mode. The research provides theoretical and numerical simulation basis for the feed mode of screw feeder.
