球磨机是选矿厂的关键设备,我单位所属铅锌矿选矿厂使用的球磨机为MQG1500×3000型.1992年,在设备安装及试生产期间,我们针对该球磨机润滑系统存在的问题进行了改造.该机原采用固体式润滑,即将机油、黄油、白蜡按比例熬制成具有一定尺寸的固体形状,放入导向盒,利用固体润滑块的自重压在轴颈上,靠轴颈与轴瓦摩擦产生的热量,逐渐溶化固体润滑块,形成一层油膜附在轴颈上而起到润滑作用.但经过短期试车运转后,证明这种润滑方式存在
The ball mill is the key equipment of the concentrator and the ball mill used in the lead-zinc ore concentrator owned by our unit is MQG 1500 × 3000. In 1992, during the equipment installation and trial production, we modified the existing problems of the ball mill lubrication system. The original machine using solid lubrication, about the oil, butter, white wax boiled in proportion to a solid shape with a certain size, into the guide box, the use of solid lubricant weight of the pressure on the journal, by journal and friction pad Heat, gradually dissolve the solid lubricating block to form a layer of film attached to the journal and play a role in lubrication, but after a short run test to prove that this lubrication exists
