揉碎机锤片自磨刃强化的试验研究

STUDY ON THE AUTOGENOUSLY GRINDING HAMMER OF THE RUBBING THROUGH EXPERIMENTS

针对锤片式揉碎机锤片棱角磨损后生产效率和质量下降的问题,利用金属材料不同硬度条件下耐磨性及磨损程度的不同,采用渗碳的方法实现揉碎机锤片不同部位的不同硬度分布,使揉碎机锤片在工作的过程中实现自磨刃效果。

For the problems of decline in production efficiency and quality after the edges and comers of rubbing harmmer wore, In view of the different wearing resistance and wearing degrees of metallic material under different hardness conditions, the carburizing method was used for the hammer, to realize different parts with different hardness. And the autogenously grinding can be achieved for the hammer during the working process.
