破碎機錘頭磨損嚴(yán)重如何處理？
來源：http://kqj188.com/ 日期：2023-06-26 發(fā)布人：
破碎機的錘頭是保證礦石物料正常生產(chǎn)的重要部件，它不僅影響砂石骨料的產(chǎn)量，而且影響成品質(zhì)量，有不少用戶都深受錘頭磨損嚴(yán)重的煩惱，那么該如何處理呢？這里冷再生機出租廠家將為大家詳細(xì)講解。
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、錘頭材質(zhì)
Reason 1: Hammer head material
錘頭的硬度和韌性是影響錘頭磨損的原因之一。一般硬度越大，錘頭的耐磨性就越大，但隨著硬度的增高，錘頭的抗沖擊韌性就會下降。因此，提高錘頭耐磨性的關(guān)鍵就是要找到兼具硬度和良好韌性的材料。
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.
處理方式：選擇高耐磨材質(zhì)的錘頭，如高錳鋼、高鉻鑄鐵、低碳合金鋼等。
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、錘頭的生產(chǎn)質(zhì)量
Reason 2: Production quality of hammer head
錘頭的制造工藝也決定其磨損難易的關(guān)鍵因素。顯而易見，如果錘頭表面或內(nèi)部由于生產(chǎn)制作過程中造成缺陷，如出現(xiàn)縮孔、裂紋、穿晶等狀況，不僅會出現(xiàn)錘頭易磨損，甚至還會造成錘頭斷裂。
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.
處理方式：要采用成熟的錘頭生產(chǎn)工藝，制定合理的鑄造和熱處理工藝。如制造高鉻鑄鐵錘頭的時候，采用立澆和合理使用外冷鐵，同時嚴(yán)控溫度，這樣制作出來的錘頭有良好的凝固順序和補縮條件，內(nèi)部組織致密，減弱晶粒粗大的現(xiàn)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、錘頭的結(jié)構(gòu)
Reason 3: Hammer head structure
錘頭的結(jié)構(gòu)和形狀對磨損也有影響，不同結(jié)構(gòu)和形狀的錘頭的熱處理性能、內(nèi)部組織有很大的差別，進(jìn)而影響耐磨性。非常的尺寸、厚度大的錘頭影響更大。另外錘頭越厚大，淬透越不容易，抗磨損性也越差。
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.
處理方式：優(yōu)化錘頭的結(jié)構(gòu)。
Processing method: Optimize the structure of the hammer head.
原因4、破碎機的技術(shù)參數(shù)
Reason 4: Technical parameters of the crusher
影響破碎機錘頭耐磨性的技術(shù)參數(shù)有轉(zhuǎn)子的功率和轉(zhuǎn)速，這兩個參數(shù)反應(yīng)了錘頭的線速度和沖擊力，關(guān)系到破碎機的生產(chǎn)能力和錘頭沖擊硬化的程度，沖擊硬化程度好，使用壽命就會延長。當(dāng)轉(zhuǎn)子的轉(zhuǎn)速過低，會使生產(chǎn)能力低，導(dǎo)致錘頭沖擊硬化不良，耐磨性差；當(dāng)轉(zhuǎn)子轉(zhuǎn)速過高的時候，雖然錘頭獲得較好的沖擊硬化，設(shè)備生產(chǎn)能力提高，但同時也會造成錘頭和襯板的強烈磨損，對錘頭的壽命也不利，同時也會增加功率消耗。
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.
處理方式：優(yōu)化技術(shù)參數(shù)，控制轉(zhuǎn)子的功率和轉(zhuǎn)速，既不能過高也不能過低。
Processing method: Optimize technical parameters, control the power and speed of the rotor, neither too high nor too low.
要想解決破碎機錘頭磨損嚴(yán)重這個問題，就要先弄清楚破碎機錘頭磨損嚴(yán)重的原因，對癥下藥。破碎機錘頭磨損嚴(yán)重的主要原因有錘頭的材質(zhì)、制造質(zhì)量及結(jié)構(gòu)設(shè)計、破碎機技術(shù)設(shè)計、給料情況及結(jié)構(gòu)中各部的間隙等。還有什么問題就來我們網(wǎng)站http://kqj188.com咨詢吧！
To solve the problem of severe wear and tear on the hammer head of the crusher, it is necessary to first understand the reasons for the severe wear and tear on the hammer head of the crusher and apply the appropriate medicine to the case. The main reasons for severe wear and tear on the hammer head of a crusher include the material, manufacturing quality, and structural design of the hammer head, the technical design of the crusher, the feeding situation, and the gaps in various parts of the structure.
