The strip comprises one or more layers of material. A belt usually has three layers: top cover, carcass, and bottom cover. The purpose of the tire body is to provide linear strength and shape. The tire body is usually a fabric or metal fabric with warp and weft threads. Meridian refers to longitudinal cords, whose resistance and elasticity limit the running performance of the belt. The latitude lines represent the entire set of horizontal cables, enabling the belt to resist cutting, tearing, and impact while having a high degree of flexibility. The most common tire body materials are steel, polyester, nylon, cotton, and aramid (a type of synthetic fiber including Kevlar). The lid is usually made of various rubber or plastic compounds specified by the belt.

When high-strength grades are required, steel conveyor belts are used. For example, the highest strength conveyor belt installed is made of steel wire rope. The strength grade of this conveyor belt is 10.000 N/mm

　　Operating at the Chuquicamata mine in Chile. Polyester, nylon, and cotton are popular in low strength grades. The range of use for aromatic polyamide is 630-3500N/The advantages of using aramid are energy saving, extended service life, and improved productivity. For example, according to reports, China Yanzhou Coal Industry Company's Baodian Coal Mine installed a 2250 N/mm, 3400
