将球磨机中各排提升条分成长度均等的几段,采用离散单元法研究了各段与磨机轴线以相同角度轴向排列时对球磨机性能的影响。分析了提升条的各种轴向排列形式对球磨机驱动功率、运行稳定性、研磨作用和提升条磨损程度的影响规律,为衬板提升条的设计、安装提出了新的思路。 Each row of lifting bars in the ball mill is divided into several sections of equal length. The discrete element method is used to study the influence of each section on the performance of the ball mill when the axis of the mill is arranged at the same angle with the axis of the mill. The influences of various axial arrangement forms of lifting bars on driving power, running stability, grinding effect and wear degree of lifting bars are analyzed, and a new idea is proposed for the design and installation of lining lifting bars.
