1. In the direction of the drum plus scraping device. In the conveyor belt along the line to increase the scraping drum scraping device to eliminate the material to the drum at the junction of the adhesive to solve the drum sticky material caused by local damage to the conveyor belt.
2. Conveyor head, tail and intermediate transfer of the transition Department of improvement. Conveyor head, tail and intermediate transfer at the transition length and transition mode, the service life of the conveyor belt has a great impact. Should be reasonable transitional design, should minimize conveyor belt rubber surface wear, to ensure that the conveyor belt does not appear folded in the middle of the phenomenon of bulge at the material does not appear to spill.
3. Flow direction adjustment. The direction of the stream has an important influence on the service life of the conveyor belt. The material flow and the conveyor belt should be operated in the same direction, which can greatly improve the service life of the equipment.
4. Conveyor at the concave transition of the pressure pulley. Practice has proved that the lack of transverse strength of the steel rope conveyor belt, start-up, pressure pulley caused by excessive local stress on the conveyor belt, leading to tear the conveyor belt, the pressure pulley will be replaced by a pressure roller can completely solve this problem .
5. Improve the conveyor belt hopper. Improve the conveyor belt hopper hopper, conveyor belt is one of the effective measures to prevent damage. Improve the hopper hopper at the junction of belt conveyors to increase its ability to pass foreign objects 2.5 times longer and larger foreign objects in the transport process is not easy to be stuck between the funnel wall and the conveyor belt and reduce the foreign body tearing conveyor belt Probability.
6. Conveyor belt local damage repair technology to extend the service life.
(1) local thermal vulcanization; that is, we often say that the conveyor belt heat fluidification needs to be equipped with vulcanizing machine.
(2) local cold and splash, the product has Germany Diput technical liquid polymer composite repair materials, but room temperature curing about 10h;
(3) local cold sticky, using the German company Di Pute patching (longitudinal rips), cold viscose T2 composite longitudinal fill crack plug (need glue gun). The advantages of these two methods are less manpower and material inputs, better wear resistance and reinforcing properties, shorter recovery time, and disadvantages of requiring high environmental requirements and failing to restore the original conveyor belt surface smoothness requirements.
(4) conveyor spray repair technology. The technology is the mixing of several liquid materials by special equipment, high pressure spray to wear the surface of the belt, according to the need to spray a certain thickness of wear-resistant layer. Curing time is short, suitable for even the local film wear, the effect is good, the disadvantage is the need for special equipment.
