Research on the Mechanism of Abnormal Temperature Rise of the Main Shaft Bearing Babbitt Lining of Ball Mill Equipment and Heat Dissipation Optimization

摘要

作为一种高效粉碎设备，球磨机通过筒体旋转驱动研磨介质与物料相互作用，广泛应用于矿石加工、建材生产等领域，为后续工艺提供符合粒度要求的粉体原料，其主轴瓦温度稳定对设备正常运行至关重要。然而实际生产中，主轴瓦温度偏高问题频发，影响设备寿命与生产效率。本文深入剖析该问题的多种成因，涵盖润滑系统故障、冷却系统问题、装配不当、负荷过大等方面，探讨相关影响因素，并给出针对性解决措施，为球磨机安全运行提供参考。

Abstract

As a highly efficient crushing equipment, the ball mill drives the interaction between the grinding media and the materials through the rotation of the cylinder body. It is widely used in fields such as ore processing and building materials production, providing powder raw materials that meet the particle size requirements for subsequent processes. The stability of the temperature of the main shaft bearing babbitt lining is crucial for the normal operation of the equipment. However, in actual production, the problem of high temperature of the main shaft bearing babbitt lining occurs frequently, which affects the service life of the equipment and production efficiency. This paper deeply analyzes various causes of this problem, covering aspects such as lubrication system failures, cooling system problems, improper assembly, and excessive load, discusses the relevant influencing factors, and provides targeted solutions, offering a reference for the safe operation of the ball mill.
