摘　　要：为提高全方位行星球磨机的研磨效果,利用离散元软件(EDEM)建立了仿真模型,对给定磨罐自转速度、不同行星盘翻转速度下的研磨介质碰撞运动进行了仿真模拟,得到最大碰撞力均值和总碰撞能量损失的变化情况。结果表明,全方位行星球磨机工作时磨罐内介质运动状态随行星盘的翻转发生周期性变化,介质间的研磨作用大于冲击破碎作用,较优的行星盘翻转速度为2r/min。In order to improve the grinding effect of omni-directional planetary ball mill,a simulation model was established by using the discrete element software(EDEM).The collision motion of grinding medium was simulated under the given rotation speed of grinding tank and different turnover speeds of planetary disk.The change laws of the average maximum collision force and total collision energy loss were obtained.The results show that the motion state of the medium in the grinding tank changes periodically with the turnover of the planetary disk,the grinding effect among the mediums is greater than the impact crushing effect,and the optimal turnover speed of the planetary disk is 2 r/min.
