摘　　要：文中针对烧结砖用双轴搅拌机搅拌叶片不同安装角对搅拌混合均匀度的影响进行了仿真研究。首先分析了物料颗粒性质及其搅拌中的碰撞运动,选择了合适的颗粒接触模型和颗粒模型,其次建立了3种搅拌叶片安装角的搅拌机模型,并利用EDEM仿真软件对搅拌混合过程进行了模拟仿真,对比分析了搅拌叶片不同安装角下的物料离散系数,得到搅拌叶片的最佳安装角度,此时物料离散系数最小,混合均匀度最好。In this paper,the influence of different installation angles of mixing blades on mixing uniformity of double-shaft mixer for sintered brick was simulated.Firstly,the properties of material particles and the collision motion in stirring were analyzed,and the appropriate particle contact model and particle model were selected.Secondly,three mixer models with different installation angles of stirring blades were established,and the stirring process was simulated by EDEM simulation software,so as to compare and analyze the material dispersion coefficient under different installation angles of stirring blades and get the best installation angle of stirring blades with the smallest dispersion coefficient and the best mixing uniformity.
