In recent years, with the progress of coal mining technology, the development trend of underground belt conveyor in the direction of long distance, large capacity, large inclination angle and high speed is becoming more and more obvious, thus constantly promoting the development of the quality of flame retardant conveyor belt. new requirements are also put forward for the technology and equipment capacity of conveyor belt manufacturers.

In the future, the conveyor will develop towards large-scale (large conveying capacity, large single machine length and large conveying inclination angle, etc.), expanding the scope of use, reducing energy consumption, reducing pollution and so on.

The conveyor belt is developing in the direction of multi-variety, high performance, lightweight, multi-function, energy saving, safety, environmental protection and long life.

Among them, the general-purpose fabric core conveyor belt is developing in the direction of high strength and less layering, and the steel wire rope core pays attention to improving the performance of anti-impact, anti-tear, wear resistance and so on.

At present, the maximum width of the conveyor belt produced by developed countries has reached 4000mm, the width of the conveyor belt can reach 6400mm, the strength of the conveyor belt can reach more than 8000N/mm, the service life of the fabric core conveyor belt is generally up to 8 years, and the steel wire core conveyor belt has been more than 20 years.

After more than 50 years of development, the conveyor belt industry has become a big country in belt production and consumption in the world, accounting for about 1/3 of the world’s belt consumption. the product has high technical content, which is conducive to saving resources and protecting the environment.

The variety series is basically in step with the international standards, and the national standards GB/T7984-2001 and GB/T9770-2001 implemented in our country are basically in line with international standards, and the conveyor belt with synthetic fiber and steel wire core as the skeleton has accounted for 80% of the output of the conveyor belt, reaching the international advanced level.

In recent years, the steel wire core flame-retardant conveyor belt for underground coal mine developed in accordance with the MT668 standard and the heat-resistant grade reaches 250Mel 300.

C’s heat-resistant conveyor belt is in a leading position in the world.
