The Importance of Flame Retardant Conveyor Belt in Coal Mine Transportation Industry

Mar. 02, 2020

The underground mining work of coal mines is affected by the geological conditions and the complexity of the coal seam. There are very strict requirements for the quality of the conveyor belt. In order to effectively improve the quality of the conveyor belt and ensure the safety and stability of underground production, it is necessary to ensure the High standard of flame retardant integral conveyor core Rapier Loom.

Flame retardant conveyor belt, also known as the whole core flame retardant conveyor belt, is made of the entire belt core after being impregnated with plasticized or vulcanized with polyvinyl chloride impregnated paste. It has the characteristics of high strength, large capacity, and balanced transportation. With good flame retardant, antistatic, impact resistance, wear resistance, corrosion resistance and other properties. The whole core flame retardant conveyor belt is a powerful type of conveyor equipment, manufactured by China Conveyor Belt Loom. The belt core is the skeleton of the whole core flame retardant conveyor belt. The use of synthetic fibers and cotton fibers can not only reduce the weight of the belt And, it also reduces the driving power and enhances the stability of the belt operation. In addition, the fabric core flame-retardant conveyor belt also has the advantages of low cost, superior safety performance, high production efficiency, and good penetration effect, so it is very common in mine production.

Maintenance method of flame retardant tape

1. During transportation and storage, the conveyor belt should be kept clean, avoid direct sunlight, rain and snow, prevent contact with acids, alkalis, oils, organic solvents and other substances that affect rubber quality, and be 1 meter away from the heating device.

2. During storage, the temperature in the warehouse should be kept between -15- + 40, and the relative humidity should be kept between 50-80%.

3. During storage, the conveyor belt must be placed in rolls, not folded, and it should be turned once a quarter during storage.

4. The running speed of the conveyor belt should not be greater than 5.0 meters / second, the material with large block size and high abrasion and the use of fixed plow-type unloading device should be used as low as possible. Exceeding the specified speed will affect the service life of the tape.

5. The relationship between the diameter of the transmission roller of the conveyor and the layer of the conveyor belt, the matching of the redirection of the transmission roller and the requirements of the groove angle of the idler should be selected reasonably according to the design requirements of the conveyor.

6. In order to reduce the impact and abrasion of the material on the tape, the feeding direction should follow the running direction of the tape; the drop of the material falling on the tape should be minimized; the feeding port should avoid directly above the roller or idler; The material section should shorten the gap between the rollers and take buffer measures. In order to prevent the tape from being scratched, the contact part between the scraper cleaning device and the unloading device of the blocking device and the tape should be a rubber plate with appropriate hardness.

During the use of the conveyor belt, the following matters should be noted:

(1) Avoid the rollers being covered by the material, causing the rotation to be ineffective, prevent the leakage of materials from getting stuck between the roller and the tape, pay attention to the lubrication of the moving parts, but do not oil the conveyor belt.

(2) Strive to avoid starting with load.

(3) Deviations in the tape should be corrected in a timely manner.

(4) Local damage to the tape should be repaired in time to avoid expansion.

(5) Prevent the tape from being blocked by racks, pillars or block materials, and prevent it from being torn.
