怎樣延長錘式破碎機(jī)的錘頭壽命

怎樣延長錘式破碎機(jī)的錘頭壽命

 河南利鑫機(jī)械設(shè)備有限公司專注大型金屬粉碎機(jī)的制造，我們的金屬粉碎機(jī)有錘式的和刀式的，今天我們就來講解，怎樣延長錘式破碎機(jī)的錘頭壽命

錘式破碎機(jī)（hammer crusher）是目前廣泛應(yīng)用于礦山，化工，冶金，建材，電力等行業(yè)的常用的破碎設(shè)備。其中，錘頭是主要的易磨損件，錘頭的好壞直接影響了破碎機(jī)的破碎效率。

目前國內(nèi)的錘式破碎機(jī)錘頭大部分是由高錳鋼制作而成的。由于高錳鋼耐磨性不夠，抗磨性差，使用壽命短，因此需要頻頻更換。

錘式破碎機(jī)（hammer crusher）錘頭在工作期間，除受到撞擊外，還受到物料的沖擊，這樣長期反復(fù)使用，錘頭的工作面就會(huì)受到破壞，使表面形狀發(fā)生變化。影響錘頭壽命的因素：

1.錘頭的結(jié)構(gòu)設(shè)計(jì)和產(chǎn)品質(zhì)量

錘頭的結(jié)構(gòu)設(shè)計(jì)和幾何形狀對其熱處理后的力學(xué)性能和內(nèi)部金相組織有很大的影響。特別是厚度尺寸大的錘頭，影響更為突出。通過對不同材質(zhì)錘頭斷裂失效形式分析可知，造成錘頭斷裂的主要原因是其內(nèi)部或表面存在不同程度的缺陷。由于缺陷的存在，使大部分錘頭在使用初期發(fā)生斷裂現(xiàn)象。因此，在錘頭生產(chǎn)中，必須制定合理的鑄造和熱處理工藝。

2.錘式破碎機(jī)的技術(shù)參數(shù)

錘式破碎機(jī)技術(shù)參數(shù)也會(huì)影響錘頭的使用壽命，其中主要的是轉(zhuǎn)子的功率和轉(zhuǎn)速。它們不僅關(guān)系到破碎機(jī)的生產(chǎn)能力，也關(guān)系到錘頭沖擊硬化的程度。錘頭沖擊硬化程度良好，其使用壽命就會(huì)有所延長。

3.所破碎物料的塊度與硬度

物料塊度越大，對其韌性要求越高，而物料硬度越高，對錘頭材料硬度要求越高。具體型號(hào)的破碎機(jī)應(yīng)采用適宜的給料粒度，這會(huì)在一定程度上延長錘頭的使用壽命。

4.錘式破碎機(jī)內(nèi)部間隙的調(diào)整

錘式破碎機(jī)內(nèi)部間隙主要是指轉(zhuǎn)子體與反擊板、蓖條以及錘頭之間的間隙。這些間隙的尺寸，會(huì)關(guān)系到蓖條及安全門附近是否有積料。如果積料存在，而錘頭無法將積料從蓖條上壓下時(shí)，錘頭就會(huì)受到嚴(yán)重的摩擦磨損。因此，在使用的過程中，必須經(jīng)常調(diào)整各部分間隙，使其處于適當(dāng)范圍之內(nèi)。

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.
