Abstract：

The mold with the length-to-diameter of 5∶1 was created by discrete-element software EDEM, and the forming of Salix biomass fuel was simulated. Then, its forming characteristics were orthogonal analyzed by four factors and three levels, and the influences of particle shape, particle size, compression speed and holding time on the dense forming of particles were studied. Furthermore, the cohesiveness, the forming density and the forming energy consumption of formed particles were used as evaluation indicators, and the primary and secondary relationships of various factors affecting them were obtained. At the same time, the forming conditions were comprehensively evaluated by the comprehensive analysis. The results show that the particle shape is pyramid-like, and the forming characteristics of Salix biomass is the best with the particle size of 1-4 mm, the compression speed of 60 mm·min-1 and the holding time of 75 s. Thus, the above research provides data reference and reference for the actual dense forming production process of sandy shrub biomass fuel such as Salix.
