(1) Causes of Longitudinal Tearing of the Conveyor Belt Vibration causes loosening and detachment of the fasteners, causing the falling of the coal linings, guides, etc.; foreign matter in the material is mixed into the material. The foreign materials are hard, angular, and the falling coal pipe is jammed to death; Roller defect, scratch caused by the roller frame; the conveyor belt was severed after the rack was caught; the cleaner was involved in the drum (return cleaner), loose bolts, there is a bouncing harbinger.
(B) Cracks in the conveyor belt
1. Due to the limitation of space size, the number of bending times of the conveyor belt is more;
2. When the joint is vulcanized, more than two vulcanizations are performed for various reasons.
(3) Causes of tearing of vulcanized joints 1. The diameter of the redirection roller is small, and the bending stress of the conveyor belt is large;
2. The quality of vulcanized joints is poor, especially when the vulcanized joints are cured more than two times, the joint strength is obviously decreased, or the canvas 3, layer is cut off, or polished, and the strength is reduced.
4, for the reversible conveyor, because the upper and lower laps can only one direction, easy to be on the belt cleaner, unloader and other equipment sharp corners scratch;
5, the conveyor has a short working period, frequent start-up, and a large instantaneous tension.
(4) Causes of Damage to the Covered Rubber Surface 1. The gap between the guide slot liner and the tape is not suitable, resulting in abnormal wear, or foreign matter embedded in the gap, causing abnormal wear or scratches.
2. The material flow velocity at the guide trough is inconsistent with the speed of the conveyor belt, and there is a large gap, which accelerates the wear of the rubber surface.
3. The roller is damaged, causing abnormal wear or scratches on the tape.
4, illegal operations, welding slag burns when overhauled.
5, the cleaner scratches.
6. Tape slippage can also cause abnormal wear of the tape.

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
