马钢桃冲矿业公司精矿加工系统,共有三台覫2100*3000溢流型球磨机,该机主轴承采用双活动油环带油润滑,节省了一套润滑油站,杜绝了漏油现象,并且结构简单维护方便,作为粉磨的主要设备,被广泛应用在煤矿、冶金矿山、化工建材等部门。但在球磨机运转时,由于其特殊的工作状况加之设备本身的安装、装配形式易造成诸多不良现象的发生,如两端滑动轴承的摆动、轴瓦温度的升高、传动齿轮产生极大噪音及过快磨损、小齿轮轴承跑外圈等等。这些问题的出现,不仅严重影响球磨机的使用寿命,且磨损部件轴瓦、大小齿轮等价格昂贵加工周期长,现场更换难度大,给生产造成很大被动。本人结合实践经验,探索球磨机常见故障的原因并进行分析,从而提出预防措施,加大对球磨机的保护力度,这对提高球磨机利用率具有十分重要的意义。 Masteel Taocheng mining company concentrate processing system, a total of three 覫 2100 * 3000 overflow ball mill, the aircraft main bearing dual oil ring with oil lubrication, saving a set of lubricating oil stations, to eliminate the oil spill, and the structure Simple and easy maintenance, as the main equipment grinding, is widely used in coal mines, metallurgical mines, chemical building materials and other departments. However, when the ball mill is running, due to its special working conditions coupled with the installation of the equipment itself, the assembly form can easily lead to many undesirable phenomena such as the swinging of the sliding bearings at both ends, the increase of the bearing temperature, the great noise of the transmission gear Fast wear, pinion bearing running outer ring and so on. The emergence of these problems not only seriously affect the service life of the ball mill, but also wear parts such as bearing bush, the size of the gear is expensive, such as long processing cycle, on-site replacement difficult, causing a lot of passive production. I combined with practical experience to explore the causes of common failures and analysis of ball mill, which put forward preventive measures to increase the protection of the ball mill, which is to improve the utilization of the ball mill is of great significance.
