怎样延长锤式破碎机的锤头寿命
中欧体育平台在线登录专注大型金属粉碎机的制造，我们的金属粉碎机有锤式的和刀式的，今天我们就来讲解，怎样延长锤式破碎机的锤头寿命
锤式破碎机（hammer crusher）是目前广泛应用于矿山，化工，冶金，建材，电力等行业的常用的破碎设备。其中，锤头是主要的易磨损件，锤头的好坏直接影响了破碎机的破碎效率。
目前国内的锤式破碎机锤头大部分是由高锰钢制作而成的。由于高锰钢耐磨性不够，抗磨性差，使用寿命短，因此需要频频更换。
锤式破碎机（hammer crusher）锤头在工作期间，除受到撞击外，还受到物料的冲击，这样长期反复使用，锤头的工作面就会受到破坏，使表面形状发生变化。影响锤头寿命的因素：
1.锤头的结构设计和产品质量
锤头的结构设计和几何形状对其热处理后的力学性能和内部金相组织有很大的影响。特别是厚度尺寸大的锤头，影响更为突出。通过对不同材质锤头断裂失效形式分析可知，造成锤头断裂的主要原因是其内部或表面存在不同程度的缺陷。由于缺陷的存在，使大部分锤头在使用初期发生断裂现象。因此，在锤头生产中，必须制定合理的铸造和热处理工艺。
2.锤式破碎机的技术参数
锤式破碎机技术参数也会影响锤头的使用寿命，其中主要的是转子的功率和转速。它们不仅关系到破碎机的生产能力，也关系到锤头冲击硬化的程度。锤头冲击硬化程度良好，其使用寿命就会有所延长。
3.所破碎物料的块度与硬度
物料块度越大，对其韧性要求越高，而物料硬度越高，对锤头材料硬度要求越高。具体型号的破碎机应采用适宜的给料粒度，这会在一定程度上延长锤头的使用寿命。
4.锤式破碎机内部间隙的调整
锤式破碎机内部间隙主要是指转子体与反击板、蓖条以及锤头之间的间隙。这些间隙的尺寸，会关系到蓖条及安全门附近是否有积料。如果积料存在，而锤头无法将积料从蓖条上压下时，锤头就会受到严重的摩擦磨损。因此，在使用的过程中，必须经常调整各部分间隙，使其处于适当范围之内。
How to extend the hammer crusher hammers life
Hammer crusher (hammer crusher) is now widely used in mines, chemical industry, metallurgy, building materials, electric power industries of the commonly used broken equipment. Among them, the hammer is the main easy wear parts, hammer a direct impact on the crusher of crushing efficiency.
The present hammer crusher hammers most is made from high manganese steel production and become. Because of high manganese steel enough wear resistance, abrasion resistance is poor, service life is short, so need to change frequently.
Hammer crusher (hammer crusher) hammer in the course of work, in addition to the hit, but also by the impact of the material, so that long-term use repeatedly, hammer face will damage, make the surface shape change. Impact hammer life of factors:
1. Hammer the structure design and product quality
Hammer the structure design and geometry shape on the mechanical properties of the heat treatment and internal metallographic organization has very big effect. Especially the size of the hammer thickness, the influence is more outstanding. According to the different material hammer fracture failure form analysis, we can conclude that cause hammer the main causes of fracture is its internal surface or there exists different degree of defects. Due to the existence of the defect, make the most of the hammer in the use of initial fracturing phenomenon. Therefore, in the hammer and render the firstborn should be established, the reasonable casting and heat treatment process.
2. Hammer crusher technical parameters
Hammer crusher technology parameters can also affect the service life of the hammer, of which the main ones are rotor power and speed. They are not only related to the crusher of production, but also related to hammer the extent of the impact hardening. Hammer head impact hardening degree good, its service life can be extended.
3. Have broken the fragmentation and hardness materials
The greater the block material, its toughness required for the high, and the higher the hardness materials, to hammer materials required for the high hardness. Specific types of crusher shall apply suitable for material of particle size, it will extend to a certain extent the service life of the hammer.
4. Hammer crusher internal clearance adjustment
Hammer crusher internal clearance is mainly refers to turn back board, plasma and article labyrinth and hammer the gap between. The gap between the size, will be related to the article labyrinth and near a product safety door whether material. If the product material existence, and hammer cannot will accumulate material from the article labyrinth press, hammer head can be severely friction and wear. Therefore, in the use process, must often adjust each part clearance, that it is in proper scope.
