Why steel cord conveyor belts failure？

Because of its long transmission distance, large load-carrying capability, and massive transit volume, steel cord conveyor belts are now the major conveying equipment in metallurgy, steel mills, coal mines, and other sectors. Steel cord conveyor belts have become particularly crucial to many heavy industrial companies, and their efficiency and operational condition are becoming incredibly valuable.

?

Steel cord conveyor belts that have been in use for a long time are susceptible to failures like wear, distortion, and cord breakage. The steel cord conveyor belt's integrity will diminish over time, eventually failing. The worst-case scenario might result in deaths and substantial financial damages for the company. We'll briefly go through the causes and solutions for steel cord conveyor belt failure to avoid a repeat of the prior problem.

?

Steel cord conveyor belts in coal mining, for instance, tend to fail due to ripping or even rupture. This is due to the fact that this problem might be triggered by a multitude of factors other than normal wear and tear. The conveyor system's maintenance crew should endeavor to extend the conveyor belt's life span, reduce unplanned downtime, and reduce injury rates to prevent the belt from breaking.

Steel cable conveyor belt joints twitch and break cords on a regular basis. The conveyor belt joint will twitch if the cover rubber is significantly worn or the joint terminal is rusted. Knowing what sort of situation you're dealing with might help you figure out what's causing it.

Fatigue-related damage

The steel cores must constantly and continually bend around the rollers and pulleys when the conveyor belt is working due to space limits. The repeatedly bent belt core is exposed to fatigue forces throughout each working cycle, resulting in repetitive fatigue damage. When increasing the life of a steel cord conveyor belt, take into account factors such as the conveyor's driving mechanism, installation size, and drum quality.

?

The tension on the conveyor belt is not distributed evenly.

Steel cable conveyor belts are frequently troughed to increase coal load-bearing capacity. The margins of the steel cord conveyor belt will encounter higher tensile stress than the center as it passes from the horizontal to the trough portion. Because of the unequal distribution of belt load, the belt is more likely to break.

?

An overpowering external force

The conveyor belt will be damaged or even fractured if it is suddenly extended as a consequence of external pressure. Material lodged in the guiding trough or distribution plate, on the other hand, increases the likelihood of the belt breaking.

?

Corrosive

Steel cord conveyor belts are used for a long time and ultimately show symptoms of wear, cracking, and aging on the upper and lower covering layers. The upper layer cracks as a result of the connection fractures. The steel chord will become exposed if not repaired immediately, enabling water to leak into the conveyor belt and cause corrosion.

?

Conclusion

Fracture events can be considerably reduced through early diagnosis of steel cord fatigue, cord breaking, and twitching flaws, as well as analysis and rectification of the defects or damage recorded.
