2 Composition and Structure of Rubber Conveyor Belts
Typical Materials Used in Belt Layers
Rubber conveyor belts usually feature multiple layers: a rubber cover layer providing wear resistance and grip; a carcass or textile/steel ply offering tensile strength; and sometimes an inner rubber lining protecting internal fibers. Materials range from natural rubber for basic applications to synthetic compounds engineered for heat or oil resistance.
Construction Methods and Fabric Reinforcement
Common constructions include fabric-reinforced belts using polyester, nylon, or cotton layers laminated with rubber, and steel cord belts where steel wires bear high tensile loads. The combination influences belt flexibility, strength, and fatigue resistance, crucial for different transport challenges.
Impact on Belt Performance
A robust multi-layer construction optimizes load-bearing and extends belt life under dynamic stresses. For instance, steel cord’s longitudinal strength prevents elongation in long conveyors, while fabric belts excel in lightweight textile or food handling systems.
What’s the real story? Choosing the right composite structure balances durability with flexibility, matching the operational profile precisely.
