(1)局部損壞(外皮損傷)：輸送帶都非常容易展現(xiàn)該類損傷，起因為皮帶輸送機(jī)轉(zhuǎn)截處、導(dǎo)料槽擋皮及毀壞的緩沖托輥及排除器等部位輕易卡死比較大的物料塊，輸送帶運作起來，便會導(dǎo)致局部的適當(dāng)損壞。
(1) Local damage (skin damage): the conveyor belt is very easy to show this kind of damage, because the large material blocks are easily stuck at the turning section of the belt conveyor, the baffle of the guide chute, the damaged buffer idler and the extractor. When the conveyor belt operates, it will lead to local appropriate damage.
耐熱輸送帶由雙層塑膠棉白帆布（滌棉布）或是聚脂白帆布左右覆有耐熱或耐高溫塑膠、經(jīng)高溫硫化黏合在一起，合適運輸175℃下列熱焦炭、混凝土、爐渣和熱鑄造件等。石橫特鋼企業(yè)裝貨機(jī)、列車受料槽輸送帶因?qū)Я喜圯^長，導(dǎo)料槽擋皮與輸送帶觸碰導(dǎo)致輸送帶膠面急速損壞，造成過局部磨多層線，而其他部位膠面還不錯的狀況。
The heat-resistant conveyor belt is made of double-layer plastic cotton white canvas (polyester cotton) or polyester white canvas, covered with heat-resistant or high-temperature plastic on the left and right, and bonded by high-temperature vulcanization. It is suitable for transporting hot coke, concrete, slag and hot castings below 175 ℃. The rubber surface of the conveyor belt of the loader and train receiving chute of Shiheng special steel enterprise was rapidly damaged due to the long guide chute and the contact between the baffle of the guide chute and the conveyor belt, resulting in local grinding to the multi-layer line, while the rubber surface of other parts was in good condition.

(2)局部損壞(貫通傷)：在輸送帶在接受物料時，經(jīng)常出現(xiàn)比較大的石頭、較尖的物料攙跟在運輸物料中，這種物料住接轉(zhuǎn)處由于緩存不足，以比較大的撞擊力撞出輸送帶，產(chǎn)生局部窟窿眼，特別是在落料較高的中轉(zhuǎn)站。倘若物料中攙跟了鋒利物件，非常容易劃傷輸送帶，導(dǎo)致大規(guī)模撕破。
(2) Local damage (through injury): when the conveyor belt receives materials, relatively large stones and sharp materials are often mixed with the transported materials. Due to insufficient buffer at the connecting place of such materials, the conveyor belt is knocked out with relatively large impact force, resulting in local holes, especially in the transfer station with high blanking. If the material is mixed with sharp objects, it is very easy to scratch the conveyor belt, resulting in large-scale tearing.
(3)鉚接部位損傷：輸送帶的鉚接部位通常變成輸送帶運用的易毀壞部位，變成輸送帶的薄弱環(huán)節(jié)，因膠接部位為膠布設(shè)備時從新鋼筋搭接硫化而成。連接頭部位解決不太好，硫化工藝規(guī)范等導(dǎo)致太早的損壞、脫膠、裂開、脫皮等景象。倘若不及時解決，連接頭部位損傷劣變速率較快，非常容易導(dǎo)致創(chuàng)痕擴(kuò)張，導(dǎo)致膠布使用壽命減少，乃會導(dǎo)致輸送帶的破裂。
(3) Damage of riveting part: the riveting part of the conveyor belt usually becomes the easily damaged part of the conveyor belt and the weak link of the conveyor belt. When the bonding part is adhesive tape equipment, it is formed by overlapping and vulcanizing from new reinforcement. The connector is not well solved, and the vulcanization process specification leads to too early damage, degumming, cracking, peeling and so on. If it is not solved in time, the damage at the connector is poor and the speed change rate is fast, which is very easy to lead to scar expansion, reduce the service life of the adhesive tape, and even lead to the rupture of the conveyor belt.
