引入离散单元法对超临速球磨机的磨矿介质运动规律进行研究。通过数值模拟,获得了磨矿介质的运动轨迹和平均接触应力。超临速球磨机能有效减少衬板损耗,提高介质的利用率和磨矿效率。
Discrete element method is introduced to study the law of grinding media of supercritical ball mill. Through the numerical simulation, the locus and average contact stress of grinding media were obtained. Supercritical ball mill can effectively reduce liner wear, improve the utilization of media and grinding efficiency.
