1. Improving the process timing belt is one of the effective measures to prevent the early damage of non-standard transmission belts. In order to improve the working capacity of the silo on each belt conveyor, the working capacity of foreign objects is increased by 2.5 times, and the foreign matter is not easy to get stuck between the pipe wall and the conveyor belt during the whole transportation process, reducing the tearing of the conveyor belt by foreign objects. The probability.
The guide skirt at the hopper makes the gap between the conveyor belt and the conveyor belt become larger and larger along the running direction of the conveyor belt, which solves the problem of coal and stone stuck between the conveyor belt and the skirt plate, and eliminates the high quality caused by this. Timing belt damage. The large dropper is installed to prevent immediate shock of the material.

2. Add scraping device to the reversing drum. In order to deal with the problem of sticking of the raw materials of the direction-changing rollers, equipment is installed on the direction-changing rollers along the transmission belt.

3. Improvement of the conveyor head, tail and intermediate transfer transition. The transition length and transition method of the conveyor head, tail and intermediate transfer place have a great influence on the service life of the conveyor belt. An effective connection design scheme should be carried out to avoid damage to the adhesive surface of the conveyor belt as much as possible, to ensure that the conveyor belt is not easy to stretch, the middle is convex, and it is not easy to leak raw materials.

4. The pinch pulley of the conveyor at the concave transition. Practice has proved that the transverse strength of the steel rope conveyor belt is insufficient. When starting, the pinch pulley causes the conveyor belt to be overstressed locally, resulting in tearing the conveyor belt. Changing all pinch pulleys to pinch rollers can completely solve this problem. .

5. The mainframe boom conveyor belt is counterweight to reduce the load. The original service life of the telescopic boom conveyor belt in the media mine is very short, and the net weight design scheme is too heavy. On the basis of satisfying the tension of the material carried by the conveyor belt, after the counterweight is reduced, the service life of the coal transported is extended from 1.5 million tons to 4.5 million tons. The original design net weight of the conveyor belt of the 20000t mining system software stacker vibrating feeder is 25 tons (including the net weight of the net weight distribution drum), and the original design plan of the tear-resistant steel chain imported from France has a net weight of less than 3 million tons.

6. Material flow direction adjustment. The orientation of freight logistics has a key impact on the service life of the conveyor belt.

7. The local damage repair technology of the conveyor belt prolongs the service life.
(1) Local hot vulcanization;
(2) Partial cold splash, the products include 1stline technology liquid polymer composite repair material from the United States, Telford from Germany, etc., but it needs to be cured at room temperature for about 10 hours;
(3) Partially cold-bonded, using German Tiptop company repair strips (longitudinal cracks), cold glue-T2 composite glue to fill the cracks vertically (special glue gun is required). These two methods have the advantages of human resources, less material resources, good wear resistance, good structural reinforcement characteristics, short acquisition time, and natural environment regulations, and cannot repair the original conveyor belt surface leveling regulations;
(4) Conveyor belt painting repair technology. The technology is to mix several liquid materials through special equipment, spray them on the wear surface of the belt under high pressure, and spray a certain thickness of wear-resistant layer as needed. The curing time is short, and it is suitable for local wear in continuous pieces. The effect is very good. The disadvantage is that special equipment is required.

8. Reasonable selection of belt type and maintenance. Effective selection of types, according to seasonal changes, immediate adjustment of line adjustment equipment, sun protection shields and winter maintenance measures can also extend the service life of the drive belt.

9. Other management issues. Strengthen the management of idlers and cleaners, and replace them in time if they are damaged. Controls on-load startup.
