输送物料中的杂质造成的皮带撕裂：

Belt tearing caused by impurities in conveying material:

输送物料中的杂质对煤炭港口来说，主要是煤炭质量不好，原煤中的大块煤和各种杂质，如铁器、木棒等，大约造成70-80%的撕裂，因而保证源头煤炭质量是防撕裂的关键。

The impurity conveying material for coal port, mainly coal quality, coal in coal and various impurities, such as iron, wooden, causing about 70-80% apart, so as to ensure the quality of coal is a key source of anti tear.

带式输送机辅助设备安装不当造成的皮带撕裂：

Belt tearing due to improper installation of belt conveyor auxiliary equipment:

带式输送机辅助设备多，衬板掉落、除铁器吸附的尖锐铁器、清扫器安装不当等都可能对输送带造成撕裂及刮扯，普通输送带没有横向保护结构，不能防止撕裂。

Belt conveyor auxiliary equipment, lining board, in addition to the sharp drop of iron and iron adsorption sweeper improper installation may cause tearing and scrape on the conveyor belt, general conveyor belt without lateral protection structure, can prevent tearing.

Three

带式输送机的结构不尽完善造成的皮带撕裂：

Belt conveyor structure is not perfect, resulting in tear belt:

因带式输送机的结构不尽完善，输送带的落料点落差大，煤流中的杂质相对速度大，冲击力大，锐利、坚硬的超长杂质容易在落料点插入输送带，造成输送带撕裂。

Because of the belt conveyor structure is not perfect, the conveyor belt blanking gap, impurity coal flow velocity, impact force, sharp, long hard impurities easily in the discharging point into the conveyor belt, the belt tearing.

Four

堵料造成的输送带撕裂：

Belt tearing caused by material blockage:

转接溜槽小，易阻碍物料及杂质通过造成输送带撕裂。

Transfer chute is small, easy to hinder material and impurities through the conveyor belt tear.
