The bolt fracture of rubber bushing can be prevented in advance. How should we prevent it? Let's take a look at the details.

　　1. 確保襯板與筒體結(jié)合良好

　　1. Ensure that the lining plate and the cylinder are well combined

　　這是從一開(kāi)始就防止螺栓斷裂的方法?？紤]襯板安裝時(shí)，可采用3~5mm的石棉板代替水泥砂漿填充襯板與缸體之間，保證襯板與缸體連接良好。

　　This is the way to prevent bolt fracture from the beginning. When considering the installation of lining plate, asbestos plate of 3 ~ 5mm can be used instead of cement mortar to fill the space between lining plate and cylinder body, so as to ensure good connection between lining plate and cylinder body.

　　盡量使用正規(guī)廠家采購(gòu)的襯墊和螺栓

　　Try to use gaskets and bolts purchased by regular manufacturers

　　由于從正規(guī)廠家采購(gòu)的墊板和螺栓質(zhì)量有保證，使用壽命長(zhǎng)，墊板容易破碎變形，螺栓配合不好，螺栓松動(dòng)。萊州金橋集團(tuán)生產(chǎn)球磨機(jī)橡膠襯板30年，服務(wù)于100多家大型企事業(yè)單位，如果您需要購(gòu)買，請(qǐng)與我們聯(lián)系。

　　Because the quality of the base plate and bolt purchased from the regular manufacturer is guaranteed, the service life is long, the base plate is easy to be broken and deformed, the bolt is not well matched, and the bolt is loose. Laizhou Jinqiao Group specializes in the production of ball mill rubber lining for 30 years, serving more than 100 large enterprises and institutions. If you need to buy, please contact us.

　　更換襯板

　　Replacement lining plate

　　為了防止螺栓斷裂，必須減小磨體對(duì)襯套和螺栓的沖擊。因此，建議將箱頭的梯形襯管改為50mm高度的扁平襯管，以降低襯管的承載能力，減輕沖擊。

　　In order to prevent bolt fracture, the impact of grinding body on Bush and bolt must be reduced. Therefore, it is suggested to change the trapezoid liner at the head of the box into a flat liner with a height of 50 mm, so as to reduce the bearing capacity of the liner and reduce the impact.

　　四、控制溫度

　　4、 Control temperature

　　高溫會(huì)引起襯板和螺栓的變形，從而導(dǎo)致斷裂。因此，為了防止此類問(wèn)題的發(fā)生，我們盡量提前將物料烘干，從而控制物料進(jìn)入磨機(jī)的溫度不超過(guò)300℃。

　　High temperature will cause deformation of lining plate and bolt, which will lead to fracture. Therefore, in order to prevent such problems, we try to dry the materials in advance, so as to control the temperature of materials entering the mill not to exceed 300 ℃.

　　更換螺栓和密封帶的螺紋

　　Replace the threads of the bolts and the sealing tape

　　考慮螺栓的螺紋部分的強(qiáng)度和使用的便利,班輪螺栓是由細(xì)牙螺紋改為普通的線程,用雙螺母鎖緊,和原來(lái)的麻繩密封與舊運(yùn)輸膠帶密封,這樣運(yùn)輸帶起密封作用,同時(shí)緩沖的作用。

　　Considering the strength of the threaded part of the bolt and the convenience of use, the liner bolt is changed from the fine thread to the common thread, locked with double nuts, and sealed with the original hemp rope and the old transport belt, so that the transport belt plays the role of sealing and buffering.

　　擰緊螺栓

　　Tighten bolts

　　為了防止襯套螺栓的斷裂源,有必要錘橢圓頭的螺栓用大鐵錘,同時(shí)收緊螺母在磨削過(guò)程中,橢圓頭的螺栓頭和襯板的螺釘孔可以合作。同時(shí)，在次擰緊完成后，在磨床停機(jī)后，更好一次換班后再擰緊，以便在各種因素引起的松動(dòng)中擰緊螺栓。

　　In order to prevent the fracture source of the Bush bolt, it is necessary to hammer the bolt with ellipsoidal head with a large hammer. At the same time, during the grinding process of tightening the nut, the bolt head of the ellipsoidal head and the screw hole of the lining plate can cooperate. At the same time, after the completion of the first tightening, after the grinder stops, it is better to tighten the bolts after a shift, so as to tighten the bolts in the looseness caused by various factors.

　　防止小墊板螺栓斷裂的方法有六種。在做預(yù)防的時(shí)候，我們可以從這六點(diǎn)開(kāi)始。如果我們?cè)谧鲱A(yù)防的時(shí)候有任何不明白的問(wèn)題，請(qǐng)告知詳情。

　　There are six ways to prevent the bolt of small base plate from breaking. When we do prevention, we can start from these six points. If we have any problems in prevention, please let us know the details.
