China General-Purpose Rubber Conveyor Belt Suppliers - Durable Solutions from a Leading Factory
Our high-quality conveyor belts are essential for various industries including building materials, chemical, coal, power, and metallurgy. These belts are designed in China by leading suppliers and manufactured in state-of-the-art factories. They efficiently transport non-corrosive and non-sharp materials such as coal, coke, sand, gravel, and cement at room temperature. Ideal for handling bulk items with a stacking density ranging from 6.5 to 2.5t/m³, our conveyor belts ensure reliable performance and durability, making them a vital component in your operational workflow.
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 Material: Polyester 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: Models include heat-resistant, cold-resistant, acid & alkali resistant, oil-resistant, and food conveyor belts. The minimum thickness of the covering adhesive on ordinary and food conveyor belts is 3.0mm (lower: 1.5mm); heat-resistant, cold-resistant, acid & alkali resistant, and oil-resistant variants require a minimum top cover of 4.5mm (lower: 2.0mm). Depending on specific conditions, upper and lower cover thickness can each be increased by 1.5mm.
