1. Improve PU conveyor belt fall hopper. The improvement of PU conveyor belt falling hopper is one of the effective measures to prevent the early damage of PU conveyor belt. To improve the fall hopper of each belt conveyor, so that it can increase 2.5 times times by the ability of foreign body, long and large foreign bodies are not easy to be stuck between funnel wall and conveyor belt in the process of conveying, and reduce the probability of foreign body tearing conveyor belt.
Falling hopper at the guide material skirt plate, so that the gap with PU conveyor belt along the direction of the conveyor belt more and more, to solve the coal, stone card in the PU conveyor belt and the problem between the skirt, eliminating the PU conveyor belt caused damage. Large drop hopper, internal installation of buffer baffle, to avoid material direct impact conveyor belt.PU Conveyor Belt
2. Add the scraping device to the drum. In the PU conveyor belt along the drum to add a scraping device, to eliminate the transfer of the drum at the material bonding problem, to solve the conveyor belt caused by the drum local damage.
3. Transfer head, tail and intermediate reprint of the transition office. The transition length and transition mode of conveying head, tail and middle reprint place have great effect on the service life of conveyer belt. Reasonable transition design should be carried out to minimize the wear and tear of the conveyor belt, to ensure that there is no folding of the conveyor belt, the middle of the bulge phenomenon, blanking place does not appear material leakage.PU Conveyor Belt
4. The belt pulley of the conveyor at the concave transition. Practice has proved that the steel rope conveyor belt transverse strength is insufficient, when starting, the pressure belt pulley causes the conveyor belt local force too big, causes the tear Pu conveyer belt, will the pressure belt pulley all changes to the pressure belt drum, may completely solve this question.
5. Large machine arm frame PU conveyor belt with heavy load reduction. The initial service life of the conveyor belt of the stacker in the coal mine system yard is very short, and the heavy design is the important reason for the excessive tension of the conveyor belt and the premature crack aging. On the basis of satisfying conveying material tension, the service life of transporting coal from 1.5 million T is extended to 4.5 million t after reducing the counterweight. 200,000 T Mine system Stacker-Reclaimer arm Conveyor belt original design counterweight is 25t (including counterweight drum weight), the original German imports tear-resistant steel belt operation less than 3 million t on the serious tensile scrap, after two reduction to reduce load after 6t, the use of domestic ordinary steel belt, operating more than 8 million T.PU Conveyor Belt
6. Material flow direction adjustment. The material flow direction has an important influence on the service life of conveyer belt, so the material flow and the conveying belt should be run in the same direction, which can greatly improve the service life of the equipment.
7. Pu conveyor belt Local damage repair technology to extend the service life. (1) local heat vulcanization; it is commonly said that the conveyor belt heat transfer needs to be equipped with vulcanizing machine. (2) Local cold spill, products have Germany US technology liquid polymer composite repair materials, but it needs to be cured at ambient temperature of 10h or so; (3) Local cold bonding, the use of Germany US company patch (longitudinal rip), cold viscose a T2 composite glue to fill the cracks (need special glue gun). The advantages of these two methods are less human and material investment, with good wear resistance and reinforcement performance, short recovery time, the disadvantage is the high requirements for the environment, can not be restored to the original conveyor belt surface formation requirements; (4) conveyor belt spraying repair technology. The technology is to mix several liquid materials by special equipment, high-pressure spray to the belt wear surface, according to the need to spray a certain thickness of wear-resistant layer. Curing time is short, apply to even pieces of local wear, the effect is very good, the disadvantage is the need for special equipment.PU Conveyor Belt
8. Reasonable choice of belt type and maintenance. Reasonable choice of type, according to seasonal changes in time to adjust the correction device along the line, plus sunscreen cover and winter maintenance measures can also prolong the conveyor belt life.
9. Other management issues. Strengthen the management of roller and cleaning device, the damage should be replaced in time. Control with
