Key Features of Polyester Conveyor Belt

  • The carcass is made of woven canvas with polyester in the warp and polyamide in the weft, providing a balanced structure for strength and flexibility
  • Low elongation in the warp direction ensures stable performance during long-distance conveying
  • Excellent trough ability in the weft direction for efficient material handling
  • Good water resistance, maintaining strength even in wet working conditions without mould growth
  • High tensile strength with excellent fatigue resistance for long service life
  • Strong anti-impact and anti-tearing performance, suitable for heavy-duty applications
  • Reliable operation under demanding conditions, including applications with drop heights over 1 meter

Applications of Polyester Conveyor Belt

Polyester conveyor belts are widely used for long-distance conveying of heavy-duty and high-density materials.

They are especially suitable for applications involving materials such as:

  • Coal
  • Ore
  • Cement
  • Other heavy bulk materials

Thanks to their strong anti-impact and anti-tearing performance, these belts can also be used in working conditions where material drop height exceeds 1 meter, ensuring reliable and stable operation.

They are commonly applied in:

  • Mining industry
  • Cement plants
  • Ports and terminals
  • Bulk material handling systems

Technical Standards and Compliance

The polyester conveyor belt is manufactured in accordance with international standards for rubber conveyor belts, including:

  • CEMA (Conveyor Equipment Manufacturers Association)
  • RMA (Rubber Manufacturers Association)
  • AS (Australian Standards)
  • GB (China National Standards)

These standards ensure consistent product quality, reliable performance and compatibility with different conveyor systems worldwide.

FAQ – Polyester Conveyor Belt

What is a polyester conveyor belt?

A polyester conveyor belt is a heavy-duty conveyor belt designed for long-distance conveying of bulk and high-density materials. It uses a polyester fabric carcass to provide high strength, low elongation, and stable performance in industrial conveying systems.

What are polyester conveyor belts used for?

Polyester conveyor belts are commonly used for transporting coal, ore, cement, aggregates, and other heavy bulk materials in mining, cement plants, ports, and industrial conveying systems.

What are the main features of a polyester conveyor belt?

Polyester conveyor belts offer high tensile strength, strong impact resistance, low elongation, excellent anti-tearing performance, and stable operation under demanding working conditions. They are especially suitable for long-distance conveying.

What is the construction of a polyester conveyor belt?

A polyester conveyor belt typically uses a woven fabric carcass with polyester in the warp direction and polyamide (nylon) in the weft direction. This structure provides strength, flexibility, and resistance to fatigue during continuous operation.

What industries use polyester conveyor belts?

Polyester conveyor belts are widely used in mining, cement production, ports, aggregate handling, bulk material transport, and other heavy industrial applications.

How is a polyester conveyor belt different from a nylon conveyor belt?

Polyester conveyor belts generally provide lower elongation and better dimensional stability, while nylon conveyor belts offer greater flexibility and impact absorption. Polyester belts are often preferred for long-distance conveying and stable tracking performance.

Are polyester conveyor belts suitable for heavy-duty applications?

Yes, polyester conveyor belts are designed for heavy-duty conveying and can perform well under high loads, abrasive materials, and long conveying distances. They are also suitable for conditions with material drop heights exceeding 1 meter.
