1. Improving the technology of synchronous belt is one of the effective measures to prevent the early damage of non-standard transmission belt. In order to improve the working capacity of the silo on each belt conveyor, the working capacity of the foreign matter is increased by 2.5 times, and the foreign matter is not easy to be stuck between the pipe wall and the conveyor belt in the whole process of transportation, so as to reduce the probability of foreign matters tearing the conveyor belt.

The guide apron at the hopper makes the gap between the conveyor belt and the conveyor belt larger and larger along the running direction of the conveyor belt, so as to solve the problem of coal and stone stuck between the conveyor belt and the apron, and eliminate the damage of high-quality synchronous belt caused by this. The large drop tube is installed to prevent the immediate impact of raw materials.

2. Add scraping device at the turning drum. In order to deal with the problem of sticking raw materials of the variable direction roller, the equipment is installed on the variable direction roller along the transmission belt.

3. Improvement of head, tail and intermediate transfer transition of conveyor. The transition length and transition mode of conveyor head, tail and intermediate transfer place have great influence on the service life of conveyor belt. The effective connection design scheme should be carried out to avoid the damage of the adhesive surface of the conveyor belt as far as possible, and ensure that the conveyor belt is not easy to stretch and stretch, and the bulge in the middle is not easy to cause the leakage of raw materials.

4. Belt pulley at concave transition of conveyor. Practice has proved that the transverse strength of the steel rope conveyor belt is insufficient. When starting, the belt pressing wheel causes the local stress of the conveyor belt to be too large, which leads to the tearing of the conveyor belt.

5. Load reduction of conveyor belt counterweight on crane boom. The original service life of telescopic boom conveyor belt in coal mine field is very short, and the net weight design scheme is too heavy. On the basis of meeting the material tension of the conveyor belt and reducing the counterweight, the service life of coal transportation is extended from 1.5 million tons to 4.5 million tons. The net weight of conveyor belt in the original design scheme of 20000 t mining system software palletizer vibration feeder is 25 tons (including net weight distribution drum net weight), and the original design scheme net weight of tear resistant steel chain imported from France is less than 3 million tons.

6. Adjust the direction of material flow. The location of freight logistics is critical to the service life of conveyor belt.

7. Local damage repair technology of conveyor belt can prolong its service life.

(1) Local hot vulcanization

(2) The products include liquid polymer composite repair materials of American lstline technology and German tefukang, but they need to be cured at room temperature for about 10 h

(3) For local cold bonding, the repair strip (longitudinal crack) of German toppop company and cold adhesive-t2 composite adhesive are used to fill the crack plug longitudinally (special glue gun is required). These two methods have the advantages of less human resources and material resources, good wear resistance, good structural reinforcement characteristics, shorter acquisition time, and higher education institutions stipulated by the natural environment, so the original belt surface leveling regulations can not be restored

(4) Painting repair technology of conveyor belt. The technology is to mix several liquid materials with special equipment, spray them on the wear surface of belt under high pressure, and spray a certain thickness of wear-resistant layer as required. The curing time is short, and it is suitable for the local wear of continuous sheets, and the effect is very good. The disadvantage is that special equipment is needed.

8. Reasonable selection of belt type and maintenance. It can also extend the service life of the belt by selecting the type effectively, adjusting the line immediately, adjusting the equipment, sunscreen isolation cover and winter maintenance measures according to the seasonal changes.

9. Other management issues. Strengthen the management of idlers and sweepers, and replace the damaged ones in time. Control load start.
