针对2 m~3的双立轴强制式混凝土搅拌机建立物理简化模型,并利用三维建模软件Pro/E建立实体模型,离散元软件EDEM对物料搅拌流动过程进行模拟仿真。结合相关试验,对双立轴强制式混凝土搅拌机搅拌过程中物料颗粒的流动轨迹,以及物料混合均匀度进行研究分析,为双立轴搅拌机结构设计提供参考。 A physical simplified model was established for a 2 m ~ 3 double vertical shaft concrete mixer. The solid model was established by using the 3D modeling software Pro / E. The discrete element software EDEM was used to simulate the material mixing flow process. Combined with the relevant experiments, the flow trajectory of material particles and the material mixing uniformity during the mixing process of the double-shaft compulsory concrete mixer were studied and analyzed, which provided references for the design of double vertical shaft mixer.
