China General-Purpose Rubber Conveyor Belt - Quality Suppliers from Reliable Factory for Building Materials and More
Ordinary conveyor belts manufactured by leading suppliers in China are essential for various sectors, including building materials, chemical industries, coal mining, power generation, and metallurgy. These conveyor systems are designed to efficiently transport non-corrosive and non-sharp materials at room temperature. They are ideal for handling a variety of materials such as coal, coke, sand, gravel, cement, and other bulk items with a stacking density ranging from 6.5 to 2.5t/mTrusted conveyor belt factories in China provide durable and reliable solutions for the smooth transportation of loose materials or bulk items, ensuring optimal performance in industrial applications
This product is refined from all cotton canvas (CC) or nylon NN polyester EP through processes such as rolling, forming, and vulcanization.
This product is suitable for different usage conditions and can be made into different structures such as edge wrapped, open edge, middle ladder, edge ladder, etc.
Specifications
Core MaterialPolyester cotton interwoven fabric TC-70 type, all cotton canvas CC-56 type
This type of conveyor belt uses fiber fabric as the core and general rubber as the covering material, with a smooth and flat surface. The core is a layered or integral fabric woven from fibers such as cotton, nylon, polyester, or vinylon.
Cotton fiber is the earliest used core material and is easy to bond with rubber. Its strength slightly increases when wet, but its breaking strength is low (mostly around 56 N/(mm·layer)), and its anti-corrosion and mildew resistance is poor. Its use is gradually decreasing.
Starting from the late 1950s, nylon fiber fabrics were used as core materials and have become the most widely used type. Nylon fiber has a strength of up to 700 N/(mm/layer), is water-resistant, corrosion-resistant, and resistant to bending fatigue; but the elastic elongation is relatively large.
Polyester fiber has similar properties to nylon fiber, but its elastic elongation during use is only half that of nylon fiber, making it a promising material for development.
Vinylon fiber has a strength of 200 N/(mm·layer), a smaller elastic elongation than nylon fiber, is easy to bond with rubber, and has good heat resistance. However, its strength decreases by 10–25% when wet, and it is only used in a few countries such as China and Japan.
When weaving the core, only one type of fiber can be used, or two types of fibers can be blended or interwoven.
Supplementary Information
Ordinary conveyor belts are divided into many specifications and models according to different usage environments and requirements:
By transportation volume and width: Commonly used models include B300, B400, B500, B600, B650, B800, B1000, B1200, B1400, B1600, B1800, B2000 (B represents width in millimeters).
By usage environment: Heat-resistant, cold-resistant, acid-alkali resistant, oil-resistant, food conveyor belts, and more. The minimum upper covering adhesive thickness for ordinary and food conveyor belts is 3.0mm (lower: 1.5mm); for heat-resistant, cold-resistant, acid-alkali resistant, and oil-resistant belts it is 4.5mm (lower: 2.0mm). Thickness can be increased by 1.5mm depending on the specific environment.
New Material Performance
The new material ordinary conveyor belt should also be suitable for high and low temperature resistance — capable of operating continuously in the temperature range of -73°C to +260°C; better resistance to chemical substances; good electrical insulation performance; anti-sticking with a low friction coefficient; and dimensional stability in high-temperature, high-pressure environments.
Execution Standard: GB/T7984-2001
Covering layer requirements: Tensile strength ≥ 15 MPa | Elongation at break ≥ 350% | Wear amount ≤ 200mm³ | Average interlayer bonding strength (longitudinal) ≥ 3.2 N/mm between layers | Interlayer bonding strength between covering adhesive and layers ≥ 2.1 N/mm.
According to purpose of use, conveyor belts can be divided into:
Q
What materials are used in the core of a general conveyor belt?
The core of a general conveyor belt can be made from cotton, nylon, polyester, or vinylon fiber fabrics. Each material offers different properties: cotton is easy to bond with rubber but has lower strength; nylon offers high strength and corrosion resistance; polyester has lower elastic elongation; and vinylon provides good heat resistance.
Q
What bandwidth options are available for general conveyor belts?
General conveyor belts are available in a bandwidth range of 300mm to 3000mm, with common models including B300, B400, B500, B600, B650, B800, B1000, B1200, B1400, B1600, B1800, and B2000, where "B" represents the width in millimeters.
Q
What temperature range can the new material general conveyor belt withstand?
The new material general conveyor belt is designed to operate continuously in a temperature range of -73°C to +260°C, making it suitable for both high and low temperature environments.
Q
What is the minimum cover adhesive thickness required for ordinary and food conveyor belts?
For ordinary conveyor belts and food conveyor belts, the minimum upper covering adhesive thickness is 3.0mm, and the minimum lower covering adhesive thickness is 1.5mm. For heat-resistant, cold-resistant, acid-alkali resistant, and oil-resistant belts, these values are 4.5mm and 2.0mm respectively.
