基于离散元分析方法,利用PFC3D模拟分析了提升条数量、高度及形状对介质运动形态、球磨机启动功率以及稳态功率的影响,并得到了这3种因素对磨机有用功的具体影响情况,所得结论为衬板的设计提供了可靠的理论依据,并为衬板的研究提出一种新的方法。 Based on the discrete element analysis method, the effect of the number, height and shape of the lifting bars on the motion modes of the media, the starting power of the ball mill and the steady state power was analyzed by PFC3D simulation. The concrete influence of the three factors on the useful work of the mill was obtained. The conclusions obtained provide a reliable theoretical basis for the design of the lining and propose a new method for the research of the lining.
