摘　　要：球磨机是选矿中不可或缺的设备,而轴承是支撑球磨机旋转筒体,降低摩擦系数,保证回转精度的重要部件。针对传统长筒球磨机使用滑动轴承出现的传动阻力大、电耗高、故障率高等问题,进行了球磨机轴承的改造。详述了球磨机轴承的技改思路和改造过程,采用装配承载量大、能承受较大冲击载荷的重载调心滚子轴承替换传统的滑动轴承。经工业应用表明,采用重载调心滚子轴承能够提高设备运转率,延长设备使用寿命,实现降本增效的目的,可为同类型矿山企业球磨机轴承改造提供参考。The ball mill is indispensable equipment in ore-dressing process,and the bearing is a key part to support the rolling cylinder of the mill,reduce friction coefficient and ensure rolling precision.In light of the problems like big transmission resistance,high power consumption and malfunction rate happening when sliding bearing is used in traditional long-cylinder ball mills,renovation on the bearing of ball mills are carried out.The paper describes the technical renovation ideas and process.The self-aligning roller bearing that has big load capacity and can endure big impact load are equipped to replace traditional sliding bearing.Industrial application shows that the self-aligning roller bearing can improve equipment function rate,prolong equipment life and is cost-effective.The renovation on the bearing of the ball mills can be used as reference by similar enterprises.
