In material handling systems across industries like mining, coal, ports, and grain, polyester conveyor belts hold an important market position thanks to their high strength, light weight, and fatigue resistance. When purchasing polyester conveyor belts, buyers often find it difficult to choose because of the many technical parameters.
The material and strength grade of the belt's carcass are core factors. The carcass of a polyester conveyor belt is made of polyester fabric, and its strength directly affects the belt's load capacity. Common polyester fabric strength grades include EP100, EP150, EP200, and EP300, with the numbers representing tensile strength per centimeter of width. For example, transporting large ore pieces in mining requires belt grades of EP200 or higher; for light-load scenarios like grain transport, EP100 is sufficient. ROYALCORP uses high-quality polyester fabric for the belt carcass, applies rubber impregnation treatment, and ensures strong adhesion with the rubber layers. The belts feature excellent tensile strength and fatigue resistance, making them suitable for various load requirements.
The rubber layer needs to match the material's characteristics. A polyester conveyor belt has a cover rubber layer and a core rubber layer. The cover layer directly contacts the materials and should be chosen based on the material type. For transporting highly abrasive materials like ore or sand, high-wear-resistant cover rubber is recommended, with a thickness of 4–6 mm. For corrosive materials like chemical raw materials, acid- and alkali-resistant cover rubber is necessary. For food materials like grain or flour, food-grade, non-toxic rubber should be used. ROYALCORP can customize rubber formulas based on the materials being transported, ensuring the belts are wear-resistant, corrosion-resistant, non-polluting, and long-lasting.
Belt specifications should match the equipment parameters. When selecting a polyester conveyor belt, the belt width, drum diameter, and other parameters need to match the conveyor precisely. The belt width should match the idler rollers, and the drum diameter determines the minimum bending radius of the belt. A drum that is too small can cause excessive bending, accelerating carcass fatigue and breakage. ROYALCORP's technical team can recommend appropriate belt widths, thicknesses, and lengths based on the customer's conveyor parameters, and provide splicing and vulcanization services to ensure the belt fits perfectly and operates smoothly without deviation.
Manufacturer strength and after-sales service should be carefully considered. A high-quality polyester conveyor belt manufacturer should have advanced production equipment and quality control systems. ROYALCORP has standardized production workshops and advanced vulcanization equipment. Every belt undergoes multiple tests, including tensile strength and adhesion tests, to ensure quality. They also offer installation guidance, usage training, and regular maintenance, providing peace of mind for customers.
Choosing the right polyester conveyor belt can effectively improve material transport efficiency and stability.
