1, conveyor belts due to impurities in the material tear. Impurities in the delivery of materials to the coal port, the main coal quality is not good, the big lump of coal and conveyor supply various impurities such as iron, sticks, etc., resulting in approximately 70-80% of the tear, thus Quality assurance is a key source of anti-tear of coal. 2, conveyor belt caused by improper installation of auxiliary equipment tear. Conveyor auxiliary equipment and more, lining drop, sharp iron adsorption separator, cleaner improper installation on the conveyor belt so may cause tearing and scraping pull, general conveyor belt no lateral protection structure, can not prevent tearing. 3, conveyor belt structure is not perfect due to tearing. The structure is not perfect because of the belt conveyor, conveyor blanking point gap between large, coal flow of impurities relative speed large impact force coal conveyor supply, sharp, hard, long impurities easy insertion point in blanking conveyor belt, causing the conveyor belt tear. 4, the conveyor belt tear caused by blocking material. Yulin supply conveyor transfer chutes small, easy to impede materials and impurities caused by conveyor belt tear. 5, the belt deviation caused by tear edges. 6, return reel coal. In addition, the aging of rubber conveyor belt joint edge so that the core inlet conveyor belt, causing rust out of Liaoning rope conveyor supply will cause tearing. 5, the relationship between the diameter of the conveyor drive roller conveyor fabric layer, driving drum bend drum as well as requirements for supporting roller groove angle should be based on the provisions of the conveyor design, reasonable selection. 6, in order to alleviate the impact of the tape material and wear, tape feed section should be shortened by idler spacing and take mitigation measures. To prevent scratch tape, contact part backgauge device scraper cleaning device and unloading device and tape should be used appropriate hardness rubber sheet, do not use fabric layer sandwiched tape head. 7, the conveyor belt in the course should note the following: A, to avoid the roller is covered by material, resulting in ineffective rotation to prevent leakage of material between the drum and the tape card, pay attention to the active portion of lubrication, but not oil conveyor . B, sought to avoid with a load start. C, tape deviation occurs, should take timely corrective measures. D, was found tapes local damage should be repaired to avoid expanding. E, to avoid arrest suffered tape racks, pillars or bulk materials, to prevent tearing Pengpo. Coal supply conveyor, conveyor supply SOUTH hose hose tape provided by Yichang South Africa Limited.
