摘　　要：针对沁心选煤厂1台SSC700原煤分级破碎机使用过程中出现破碎齿辊磨损严重、齿环齿头断裂、齿辊窜轴的问题,结合分级破碎机齿辊的整体结构和外观尺寸,采取更换齿型结构、优化齿环锁紧方式的措施对破碎齿辊进行改造升级。生产实践表明,改造后的齿辊具有耐磨性能好、破碎效率高、可靠性能高的特点,在实际生产中取得了较好的效果。In view of the serious wear of the crushing tooth roller,the fracture of the tooth ring tooth head and the passing shaft of the tooth roller during the use of an SSC700 raw coal crusher in Qinxin coal preparation plant,combined with the overall structure and appearance size of the tooth roller of the grading crusher,the measures of replacing the tooth shape structure and optimizing the tooth ring locking method were adopted to transform and upgrade the crushing tooth roller.Production practice shows that the transformed tooth roller has the characteristics of good wear resistance,high crushing efficiency and high reliability performance,and has achieved good results in actual production.
