摘　　要：以立式螺旋搅拌磨为研究对象,设计了一种带导流板的磨筒,通过离散单元仿真软件对磨机进行模拟仿真,研究了导流板对磨机性能的影响。仿真模拟的速度云图及碰撞数据表明导流板能够提高磨机内研磨介质的速度梯度以及碰撞能量,从而提高破碎效果,为立式搅拌磨的优化设计提供了一定的参考。Taking a vertical spiral stirred mill as the research object,a mill cylinder with a deflector is designed,and the impact of the deflector plate on the mill performance is studied by simulating the mill with discrete element simulation software.The velocity clouds and collision data of the simulation show that the deflector can improve the velocity gradient and collision energy of the grinding media in the mill,thus improving crushing effect,which provides certain reference for the optimization design of the mill.
