1, due to impurities in the material conveying belt tear. Impurities in the transportation of materials for coal port, the main coal quality is poor, the big lump of coal and a variety of impurities, such as iron, sticks, etc., resulting in approximately 70-80% of the tear, thus ensuring that the source of coal quality is the key ripstop.

2, auxiliary equipment caused by improper installation of belt conveyor belt tear. Belt conveyors auxiliary equipment and more, linings fall, adsorption separator sharp iron, sweeper improper installation and so may cause tearing and scraping on the conveyor belt pull, general conveyor belt no lateral protection structure, can not prevent tearing.

3, the structure is not perfect conveyor belt caused by tearing. The structure is not perfect because of conveyor, conveyor blanking point gap between large, coal flow of impurities large relative velocity, impact force, sharp, hard, long impurities easily inserted in the blanking point belt, causing conveyor tear.

4, resulting in blocking material conveyor belt tear. Transfer chute is small, easy to hinder materials and impurities by causing belt tear.

5, the conveyor belt of the deviation caused by pulling edges.

6, return Reel coal.

In addition, the aging of the conveyor belt side glue joints core water, causing rust out of rope, can also cause tearing.
