The main roles of liners are to protect the mill shell and promote effective ball motion for grinding. For this reason the liner profile is carefully selected to ensure that the productivity is maximized and due liner replacement is made when this objective is no longer met. These issues have been extensively studied on shell liners as mill relining is a significant cost component of ball milling. To date, not much has been written about end-liners and the kind of forces they are subjected to. A discrete element method (DEM) simulation scheme is conducted to look at how ball size distribution, mill filling, end-liner configuration and shape affect the distribution of forces acting on the liners that were assessed to understand end-liner wear and damage. The results showed how forces varied both radially and tangentially for the different sections of end-liner, with important insights drawn for end-liner manufactures.

使用DEM软件探索末端划线器的力量

衬套的主要作用是保护磨机外壳并促进磨球的有效滚珠运动。因此，要仔细选择衬管轮廓，以确保最大程度地提高生产率，并在不再满足该目标时进行适当的衬管更换。由于磨机衬里是球磨的重要成本组成，因此在壳衬上已对这些问题进行了广泛研究。迄今为止，关于端衬及其承受的作用力的文献还很少。进行了离散元方法（DEM）模拟方案，以研究球尺寸分布，轧机填充，端衬结构和形状如何影响作用在衬板上的力的分布，这些力经过评估可以了解端衬的磨损和损坏。
