| 摘 要： | 现有文献将研磨体对球磨机筒壁的作用力简化为集中力,不利于反映不同位置受力状况.根据极坐标系下研磨体运动的轨迹方程,推导出离心力、重力和冲击力的计算公式.以直径2.1m的球磨机为例,利用Matlab计算并绘制力与角度的关系图,直观地表达了研磨体重力和冲击力是影响球磨机寿命的关键因素,主要分布于方位角140°～220°.结论可为后续的简体结构设计和疲劳试验以及衬板选择提供参考.

| Abstract: | The present literatures simplified the stress generated by grinding media acting on ball mill inner wall as concentrated forces,which is not conducive to reflect the force status of different position.Formulas of centrifugal force,gravity and impact are deduced,according to the motion trajectory equations of grinding media under polar coordinate system.Taking a diameter of 2.1m ball mill as an example,Matlab is used to calculate and plot the diagram of force-angle relationships,intuitively expressed that gravity and impact force,mainly distributed over polar angle 140 °～220 °,are the key factors affecting ball mill＇s life.The conclusion can provide as reference for subsequent structure design,fatigue test and liner choosing. |
