金属撕碎机在工作过程中主要通过刀片切割原理实现对废旧金属的破碎加工，其应用原理类似于剪板机的上下切刀，利用两刀之间的刃角实现对废旧金属的切条撕片作业。在金属撕碎机的使用寿命上由于设备特殊原理所限制，其使用寿命主要表现在刀片的使用寿命上，其具体表现为刀口磨损变钝、刀片崩口等因素，其次在影响因素上还有主轴问题，由于金属撕碎机通常为双轴或四轴结构在遇到大型废钢撕碎加工时如设备没有完整的电路防护装置对主轴扭矩进行限制，在遇到大型废钢时极易造成扭矩过大导致的主轴弯曲，从而严重影响刀片配合精度造成设备出现较大的安全故。再次设备的日常维护保养，金属撕碎机在运行过程中由于转速较低在主轴承的润滑上可适当进行，但对于减速机齿箱的危害上绝对不能马虎，以免造成齿轮过早磨损。
通过以上说明在金属撕碎机的应用过程中对设备使用寿命起到决定性作用的因素主要由：刀具质量、设备减速机维护、主设备润滑维护、设备设计可靠性等因素决定。以上仅为简略解答，如需了解更多请继续关注。
Metal shredding machine in the working process of the main through broken blade cutting principle of scrap metal processing and its application principle is similar to the guillotine shears incised on the knife, using the blade Angle between the two knife cutting torn piece of homework for scrap metal.On the service life of metal shredding machine due to equipment limited by special principle, the service life of the main performance on the service life of the blade, the specific performance for the blade wear dull, blade crack, secondly in terms of influencing factors and main problems, because the metal shredding machine for biaxial or four axis structure usually encountered in large scrap pieces processing such as equipment did not complete the circuit protection device for main shaft torque limit, when meeting a large scrap steel bend easily lead to excessive torque of the spindle, which seriously affect the blade with a larger precision equipment safety reason.Again equipment daily maintenance, metal shredding machine due to the low speed in the process of operation on the lubrication of main bearing can be appropriately, but for the dangers of speed reducer gear box must not be careless, lest cause premature gear wear and tear.
Through the above description in the process of the application of metal shredding machine factors play a decisive role to the service life of the equipment is mainly composed of: reducer tool quality, equipment maintenance, design of main equipment lubrication maintenance, equipment reliability factors.
