破碎机的锤头是保证矿石物料正常生产的重要部件，它不仅影响砂石骨料的产量，而且影响成品质量，有不少用户都深受锤头磨损严重的烦恼，那么该如何处理呢？这里冷再生机出租厂家将为大家详细讲解。

The hammer head of a crusher is an important component to ensure the normal production of ore materials. It not only affects the output of sand and gravel aggregates, but also affects the quality of finished products. Many users are deeply troubled by the severe wear and tear of the hammer head, so what should be done? Here, the rental manufacturer of the cold regeneration machine will provide a detailed explanation for everyone.

原因1、锤头材质

Reason 1: Hammer head material

锤头的硬度和韧性是影响锤头磨损的原因之一。一般硬度越大，锤头的耐磨性就越大，但随着硬度的增高，锤头的抗冲击韧性就会下降。因此，提高锤头耐磨性的关键就是要找到兼具硬度和良好韧性的材料。

The hardness and toughness of the hammer head are one of the reasons that affect the wear of the hammer head. The higher the hardness, the greater the wear resistance of the hammer, but as the hardness increases, the impact toughness of the hammer will decrease. Therefore, the key to improving the wear resistance of hammer heads is to find materials that combine hardness and good toughness.

处理方式：选择高耐磨材质的锤头，如高锰钢、高铬铸铁、低碳合金钢等。

Processing method: Choose a hammer head made of high wear-resistant materials, such as high manganese steel, high chromium cast iron, low-carbon alloy steel, etc.

原因2、锤头的生产质量

Reason 2: Production quality of hammer head

锤头的制造工艺也决定其磨损难易的关键因素。显而易见，如果锤头表面或内部由于生产制作过程中造成缺陷，如出现缩孔、裂纹、穿晶等状况，不仅会出现锤头易磨损，甚还会造成锤头断裂。

The manufacturing process of the hammer head also determines the key factor that makes it difficult to wear. Obviously, if defects are caused on the surface or inside of the hammer head during the production process, such as shrinkage, cracks, transgranular, etc., it will not only cause easy wear of the hammer head, but also cause the hammer head to fracture.

处理方式：要采用成熟的锤头生产工艺，制定合理的铸造和热处理工艺。如制造高铬铸铁锤头的时候，采用立浇和合理使用外冷铁，同时严控温度，这样制作出来的锤头有良好的凝固顺序和补缩条件，内部组织致密，减弱晶粒粗大的现象。

Treatment method: Mature hammer production technology should be adopted, and reasonable casting and heat treatment processes should be developed. When manufacturing high chromium cast iron hammerheads, vertical casting and reasonable use of external cooling iron are used, while strictly controlling temperature. This way, the hammerheads produced have good solidification sequence and shrinkage conditions, dense internal structure, and reduces the phenomenon of coarse grains.

原因3、锤头的结构

Reason 3: Hammer head structure

锤头的结构和形状对磨损也有影响，不同结构和形状的锤头的热处理性能、内部组织有很大的差别，进而影响耐磨性。特别的尺寸、厚度大的锤头影响更大。另外锤头越厚大，淬透越不容易，抗磨损性也越差。

The structure and shape of a hammer also have an impact on wear, and the heat treatment performance and internal structure of hammers with different structures and shapes vary greatly, thereby affecting wear resistance. A hammer with a special size and thickness has a greater impact. In addition, the thicker the hammer head, the harder it is to harden and the poorer its wear resistance.

处理方式：优化锤头的结构。

Processing method: Optimize the structure of the hammer head.

原因4、破碎机的技术参数

Reason 4: Technical parameters of the crusher

影响破碎机锤头耐磨性的技术参数有转子的功率和转速，这两个参数反应了锤头的线速度和冲击力，关系到破碎机的生产能力和锤头冲击硬化的程度，冲击硬化程度好，使用寿命就会延长。当转子的转速过低，会使生产能力低，导致锤头冲击硬化不良，耐磨性差；当转子转速过高的时候，虽然锤头获得较好的冲击硬化，设备生产能力提高，但同时也会造成锤头和衬板的强烈磨损，对锤头的寿命也不利，同时也会增加功率消耗。

The technical parameters that affect the wear resistance of the crusher hammer head include the power and speed of the rotor. These two parameters reflect the linear speed and impact force of the hammer head, and are related to the production capacity of the crusher and the degree of impact hardening of the hammer head. If the impact hardening degree is good, the service life will be extended. When the rotational speed of the rotor is too low, it will lead to low production capacity, poor impact hardening of the hammer head, and poor wear resistance; When the rotor speed is too high, although the hammer head achieves good impact hardening and improves equipment production capacity, it also causes strong wear on the hammer head and lining plate, which is not conducive to the lifespan of the hammer head and also increases power consumption.

处理方式：优化技术参数，控制转子的功率和转速，既不能过高也不能过低。

Processing method: Optimize technical parameters, control the power and speed of the rotor, neither too high nor too low.
