SW conveyor belts are high-performance conveying equipment: Wide application: Suitable for scenarios with large drops, high loads, and high-speed conveying, commonly used in mining, ports, and other industries. Superior structure: Thin belt core, replacing multi-layer with single/double layer, thickness reduced by 7% – 17%, single roll length up to 400 – 500 meters, adaptable to small rollers. Strong performance: Using special weaving methods, high tensile strength, low elongation; special organizational structure, strong impact absorption, good toughness, and long service life. Suitable for conveying materials with large drops, high loads, and high-speed conditions, widely used in mining, ports, power, and other industries.
SW conveyor belts are commonly known as straight warp canvas conveyor belts.
SW canvas refers to straight warp canvas. Conveyor belts made with this canvas as the skeleton material are called SW conveyor belts. They are also often called “soft steel wire” conveyor belts because their flexibility is far greater than steel wire ropes, and their strength is close to that of high-strength steel wire ropes, offering advantages in energy saving.
In addition, in different application scenarios and companies, it may also have some specific names. For example, SW integral steel mesh conveyor belts are also a type of SW conveyor belt, suitable for vertical material conveying, and are widely used in the metallurgical, chemical, cement, power, and grain industries. There are also SW wear-resistant and impact-resistant conveyor belts, often used for material conveying in the building materials industry.
• Material conveying: In mining, metallurgy, building materials, and power industries, it is used to convey various blocky, granular, and powdery materials, such as ores, coal, cement, and sand and gravel, to achieve long-distance transportation of materials and the connection between different production stages.
• Transportation: In the chemical and grain industries, it can be used to transport chemical products and grains, ensuring the smooth flow of products during production, processing, storage, and transportation.
• Loading and unloading operations: In ports and docks, it undertakes the loading and unloading of goods, quickly transferring goods from ships to shore or loading goods from the shore onto ships, improving port operating efficiency.
• Automated production process connection: In some factories with a high degree of automation, the SW conveyor belt, as part of the production line, connects different production equipment to achieve automatic material conveying and continuous and automated production processes, improving production efficiency and product quality stability.
Thin core: Using single or double layers instead of multi-layer structures reduces the total thickness by 7%~17%, improves bending resistance, allows smooth operation even with smaller roller diameters, and allows single-roll lengths of 400~500 meters.
High strength: Reinforced SW belt design provides excellent tear resistance. SW conveyor belts prevent foreign object penetration and have excellent heat resistance. Multiple composite cover layers meet specific application needs. SW conveyor belts combined with heat-resistant composite materials provide excellent heat resistance up to 300℃. Using high-denier fiber special weaving methods improves the tensile strength of the fabric layer, and the conveyor belt has a small elongation rate during use.
Good toughness: The special structure of STRAIGHT WARP absorbs impact force better than general EP/NN conveyor belts, improving the service life of the conveyor belt.
