锤片是锤片式粉碎机中重要的工作零件。实践表明,它是易损零件。因而锤片的设计优劣关系到粉碎机的工艺性能、机械性能及经济性,应予以重视。设计锤片除了要考虑锤片材料的选用及热处理等,还必须使锤片达到动力平衡。所谓锤片的动力平衡,就是锤片在打击物料时,其本身受到物料给予的反冲击力不传递到销轴上。如锤片能达到动力平衡就可以减少锤片销孔的磨损和整台机器的振动。从受力分析可看出:只要反冲击力作用在锤片的撞击 Hammer is a hammer mill important part of the work. Practice shows that it is a fragile part. Therefore, the design of the hammer is related to the merits of mill technology, mechanical properties and economy, should be valued. Hammer design in addition to consider the choice of materials and heat hammer hammer, etc., must also make the hammer to achieve power balance. The so-called dynamic balance of the hammer, is the hammer in the fight against the material, its own by the material to give the impact force is not delivered to the pin. If the hammer can achieve dynamic balance can reduce the hammer pinhole wear and vibration of the entire machine. From the stress analysis can be seen: as long as the impact of anti-impact hammer impact
