Abstract：

In order to study the particle motion trajectory and the influences of various factors on the energy consumption during the dense forming process of Salix particle, the discrete element software EDEM was used for simulation and analysis, and the dense forming process of Salix particle was simulated. Then, the motion trajectories of particle with different particle diameters were analyzed, and the influences of particle diameters, particle shape and compression speed on the energy consumption were comparatively studied. The results show that the motion trajectories of large particles (Ф3.2 and Ф3.0 mm) are quasi-linear during the dense forming process, and the motion trajectories of small particles (Ф1.0 and Ф0.8 mm) are quasi-linear in the early stage of dense forming, but the motion trajectory in the later stage of dense forming fluctuates and rotates. Furthermore, among the three kinds of energy consumption influencing factors, the particle shape has the greatest influence on the energy consumption of Salix during the dense forming, the spherical particles have the best forming effect with the most energy consumption, and the flake particles have a poor forming effect with the least energy consumption. Finally, the effect of particle diameter is small, and the influence of compression speed on the energy consumption is not significant.
