All kinds of surface damages in the operation of conveyor belt have many adverse effects on the safe operation of conveyor belt. In order to find out the crux of the problem, after a long time of on-site analysis, the causes of conveyor belt damage are as follows:

　　(1)给煤机料斗太直，无缓冲。大块煤矸石或煤炭直接撞击输送带，冲击力特别大，造成输送带表面损坏。

　　(1) the hopper of coal feeder is too straight without buffer. The large gangue or coal directly impacts the conveyor belt, which causes the surface damage of the conveyor belt.

　　(2)输送机司机、检验员意识差。如果托辊使用时间过长，没有及时更换，中间的托辊就会磨损，传送带也会损坏。

　　(2) the safety awareness of the conveyor driver and inspector is poor. If the idler is used for a long time and is not replaced in time, the idler in the middle will be worn and the conveyor belt will be damaged.

　　(3)低托辊支座稀疏，承载过大。当输送带的运煤车通过时，它会在两个托辊之间凹陷，导致托辊弯曲，破坏输送带。

　　(3) the support of low idler is sparse and the load is too large. When the coal truck of the conveyor belt passes through, it will sink between the two idlers, resulting in the bending of the idlers and damaging the conveyor belt.

　　(4)在操作过程中,由于不正确的关节或不当的懒汉,传送带将倾向于机架的一侧,可以挠的吊架或架,这可能会导致当地输送带磨损或损坏,甚大的凹槽,将缩短输送带的使用寿命。传送带上的边缘刮擦大多是由于跑偏造成的。

　　(4) in the process of operation, due to incorrect joints or improper lazy people, the conveyor belt will tend to one side of the rack, which can flex the hanger or rack, which may cause wear or damage to the local conveyor belt, or even large grooves, which will shorten the service life of the conveyor belt. The edge scraping on the conveyor belt is mostly caused by deviation.

　　(5)在装载点，输送带被尖利的物料刺穿，造成输送带损坏。

　　(5) at the loading point, the conveyor belt is punctured by sharp materials, causing damage to the conveyor belt.

　　(6)两个带式输送机再次重叠，没有缓冲仓，大块的煤和混凝土直接撞击带式输送机，会对带式输送机造成伤害。

　　(6) the two belt conveyors are overlapped again, there is no buffer bin, and the large coal and concrete directly impact the belt conveyor, which will cause damage to the belt conveyor.

　　(7)煤矸石过大，碾碎辊框或辊框掉落，刮伤输送带。

　　(7) if the gangue is too large, the crushing roll frame or roll frame will fall off and the conveyor belt will be scratched.

　　(8)雷管针丝和吊在架上的铁丝会撕裂输送带。

　　(8) the detonator needle wire and the wire hanging on the frame will tear the conveyor belt.

　　(9)大型物料或煤炭夹在漏斗挡板导槽或回程部分托辊支架与输送带之间，可能划伤输送带。

　　(9) if large materials or coal are sandwiched between the guide groove of the funnel baffle or the idler bracket of the return part and the conveyor belt, the conveyor belt may be scratched.

　　(10)煤矸石或金属物体附着在料斗和挡板上，或输送带在返回部分的滚筒框与输送带之间损坏。

　　(10) the gangue or metal object is attached to the hopper and baffle, or the conveyor belt is damaged between the roller frame of the return part and the conveyor belt.

　　(11)输送带头部清洗器刮擦输送带表面的金属或其它杂物，对输送带造成损坏。

　　(11) the cleaner at the head of the conveyor belt scrapes the metal or other sundries on the surface of the conveyor belt, causing damage to the conveyor belt.

　　(12)小车张紧容易掉下，导致皮带撕裂。

　　(12) the tension of the trolley is easy to fall, resulting in the belt tearing.

　　(13)由于加工质量差或维修保养管理跟不上辊筒，密封不严密，轴承损坏，轴承变成煤尘或水，加油不及时。在中间，必须克服更大的阻力，而且惰轮不灵活。这样，托辊的转速就落后于输送带的转速，导致输送带的过度磨损和损坏。

　　(13) due to poor processing quality or maintenance management can not keep up with the roller, the seal is not tight, the bearing is damaged, the bearing becomes coal dust or water, and the oil filling is not timely. In the middle, greater resistance has to be overcome and the idler is not flexible. In this way, the speed of the idler is behind the speed of the conveyor belt, resulting in excessive wear and damage of the conveyor belt.
