溢流式球磨机是选矿分厂矿石细碎的主要设备,其进料部空心轴衬套多次出现固定螺栓断裂、衬套外窜,导致润滑油污染。分析引起衬套损坏的原因,介绍所采取的对策,即改变衬套的部分材质、增加内六方螺栓固定连接等。改造后空心轴衬套运行效果较好,泄漏率大大降低。 Overflow ball mill is the ore dressing plant ore crushing the main equipment, the hollow part of the feed shaft bushing fixed bolt break several times, the bushing outside channeling, resulting in lubricating oil pollution. Analysis of the causes of damage to the bushing, describes the countermeasures taken, that is, to change the material of the bushing to increase the internal six-bolt connection and so on. After the transformation of hollow shaft bushing running better, the leakage rate is greatly reduced.
