An endless conveyor belt is a type of conveyor belt processed into a jointless ring shape during manufacturing. Its core advantage stems from the unique jointless design. It is usually made by processing a flat conveyor belt through vulcanized joints (also known as hot bonding), with no joints in the belt core, avoiding the problem that joints of traditional conveyor belts are prone to premature failure. Therefore, the belt body does not need to be shortened during its service life.
This jointless structure enables smooth belt connection, which not only ensures fast and efficient on-site installation but also greatly reduces the incidence of on-site failures. At the same time, the strength of the joint can reach 90% of the strength of the tape itself, and there are no obvious joint defects on the tape surface, making the transportation process more balanced and the use elongation smaller.
The belt core of the endless conveyor belt is made of high-quality materials, commonly including high-quality cotton or cotton-polyester interwoven canvas (generally 2-8 layers), and nylon canvas or polyester canvas can also be used as the strength layer to ensure the belt body has good load-bearing capacity and durability. To meet the needs of different industries, our company can produce various types of endless conveyor belts according to customer requirements, including ordinary type, heat-resistant type (≤120℃), cold-resistant type (not lower than -40℃), acid and alkali resistant type, high-temperature resistant type (not higher than 150℃) and sanitary type, covering customization requirements in terms of length, width and thickness.
| Endless Conveyor Belt Length (m) | Limit Deviation (mm) |
| Length < 15 | ± 50 |
| Length 15 - 20 | ± 75 |
| Length > 20 | ± 0.5% of the belt length |
Our company can produce ordinary, heat-resistant (≤120oC), cold-resistant (not lower than -40oC), acid and alkali resistant, high-temperature resistant (not higher than 150oC) as well as hygienic endless conveyor belts with appropriate length, width and thickness according to customer requirements.
The structure and processing method of the endless conveyor belt are roughly the same as those of ordinary conveyor belts, but the joint treatment method is unique—it does not use mechanical joints, but is vulcanized into a whole by heating and pressing, so it is also called a jointless conveyor belt. There are three main joint methods: (1) Directly vulcanized into a ring belt; (2) Leave a green joint during vulcanization, and heat and press the joint part on site according to requirements when in use; (3) On-site bonding with adhesive. This design without mechanical joints makes it run more smoothly, especially suitable for material conveying scenarios in mineral processing, chemical fertilizer and other departments.
With excellent performance, endless conveyor belts play an important role in many industries:
Industrial Manufacturing: Used to convey raw materials such as ore, coal, cement, as well as semi-finished parts, ensuring the continuity of the production process.
Logistics and Warehousing: Widely used in sorting lines and assembly lines to realize efficient transfer of packages and goods, improving logistics processing efficiency.
Mining/Building Materials: In scenarios such as mines and cement plants, it undertakes long-distance transportation of heavy materials and adapts to harsh working environments.
Food Processing: When food-grade rubber material is used, it can safely convey food raw materials such as grain, fruits and vegetables, meeting the hygiene requirements of the food industry.
In conclusion, endless conveyor belts have become an ideal choice for material conveying in various industries due to their advantages such as no joints, convenient installation, stable operation and strong durability. Whether in heavy industrial production or fine food processing, it can provide customized solutions according to different needs, effectively improving conveying efficiency and reducing maintenance costs. With the continuous improvement of requirements for conveying equipment in various industries, endless conveyor belts will surely play a more important role in the field of material conveying in the future
