NN conveyor belt is a kind of conveyor belt with high-strength nylon fiber fabric layer as the skeleton material. It adopts the structural design of warp and weft interweaving to ensure excellent tensile strength, wear resistance and impact resistance. As a kind of fabric layered belt, the structural design of NN conveyor belt provides higher load-bearing capacity and is widely used in heavy industries such as coal mining, steel, cement, and chemical industry.
NN conveyor belts are constructed with multiple layers of nylon fibers interwoven in warp and weft to ensure high tensile strength and abrasion resistance. The fibers of each layer of nylon fabric are interwoven and arranged in the longitudinal (warp) and transverse (weft) directions, giving it good load-bearing capacity and impact resistance. The following are the key features of this product:
With its unique warp and weft interwoven fabric structure, NN conveyor belts provide high tensile strength, abrasion resistance, impact resistance, and heat resistance, and at the same time greatly improve the reliability and service life of the belts. It is ideal for long-duration, high-intensity material handling in heavy industry, increasing productivity and reducing downtime and maintenance costs.
