What is the history of the development of conveyor belts

作者: Release Date: 2019-12-19 Author: Click:

The conveyor belt appeared in the second half of the 17th century. Since then, the belt conveyor has become a new tool that cannot be ignored in material transportation. But it wasn't until 1795 that the belt used to transport bulk materials became popular, and in the beginning it was used only for short distance grain bags. Since the 20th century, the application range of conveyor belts has expanded rapidly. In the 1920s, the use of belt conveyors was very common, such as in large factories, coal mines and other industries. The conveyor belt uses cotton canvas as a fabric belt core, which gradually developed into a synthetic conveyor belt during World War II.


Status of China's conveyor belts : After rapid development in recent years, China's conveyor belts have become the world's largest producers of conveyor belts. Enterprise production scale, number of conveyor belt manufacturers and total output are large. However, the structure of various conveyor belts is unreasonable. Ordinary conveyor belts account for a quarter of the total conveyor belts, which objectively reflects that low-strength, short-life cotton canvas conveyor belts still occupy a large proportion in China's conveyor belt industry.

输送带发展有着怎样的历程

Status of conveyor belts in developed countries abroad: ordinary cotton canvas conveyor belts are outdated; chemical fiber canvas conveyor belts have gradually changed from replacement and are a straight warp and weft fabric core conveyor belt with good strength properties. The output of straight warp and weft fabric core conveyor belts accounts for 10-20% of the total output of fabric core conveyor belts. High-strength (breaking strength not less than 2000 kN · m) conveyor belts mostly use steel wire rope core structures, and the output of steel wire rope conveyor belts accounts for about 25% of the total output of the conveyor belt.


The development of conveyor belt trends: The market share of ordinary cotton canvas conveyor belts will gradually squeeze out and be replaced by high-strength, multi-purpose conveyor belts. Eliminating cotton canvas cores, using polyester nylon canvas cores, developing straight warp and weft fabric cores, increasing the total output of fabric cores, and improving the strength specifications of fabric cores are the development direction of China's trend conveyor belts and their cores.
