球磨机中空轴进浆磨损是矿山企业常见的故障隐患,该隐患如长期存在而得不到有效解决,最终必然会酿成中空轴磨漏的恶性事故。中空轴进浆磨损是一个较为缓慢的过程, 从进浆到磨漏往往要经历5-6年甚至更长的时间;而且,中空轴进浆会有外观表现,即进入中空轴的矿浆,其浆水会从衬套与中空轴的联接法兰处泄漏出来。关于“球磨机进料部密封结构的改造措施”的文章,贵刊已有多期发表,但采取的措施基本只是弥补现有结构的缺陷, 而未对这些有缺陷的结构作深入研究。本文提出的这种设计结构,旨在从根本上解决中空轴进浆磨损问题。下面就常见的两种中空轴密封结构所存在的缺陷简要分析并提出相应的改造措施。
Ball mill hollow shaft into the pulp wear is a common mining enterprise hidden faults, such as hidden dangers such as long-term existence can not be effectively resolved, eventually leading to hollow shaft abrasion accidents. Hollow shaft into the pulp wear is a relatively slow process, from the slurry into the mill often tend to go through 5-6 years or even longer; Moreover, the hollow shaft into the slurry will have the appearance of performance, that is, into the hollow shaft of the slurry, which Slurry leaks from the coupling flange of the bushing and hollow shaft. As for the articles on the reform of the seal structure of the feed section of a ball mill, your journal has been published for a long period of time. However, the measures taken are basically to make up for the shortcomings of the existing structures without making in-depth studies on these defective structures. This design of the proposed structure, designed to fundamentally solve the hollow shaft into the pulp wear problem. The following is a brief analysis of the common defects of the two hollow shaft seal structure and propose the corresponding transformation measures.
