What Is a Conveyor Belt?

Mar. 16, 2021

A conveyor belt is the carrying medium for a conveyor system, one of the many types of conveyor systems available today. Each conveyor system requires different modules to operate properly and to perform the tasks required by the belt.The range of different tasks depends on the weight required, the speed required and the throughput of the product on the conveyor system.

Construction of conveyor belts

Belts are made up of one or more layers of material. Belts are usually divided into three layers: the top cover, the carcass and the bottom cover. However, in some cases, more layers are required depending on the goods moving on the conveyor system.

The weft represents the complete set of transverse cables that enable the belt to resist cuts, tears and impacts, while also being highly flexible to ensure that the system is less prone to breakage.

The most commonly used carcass materials are steel, polyester, nylon, cotton and aramid, while the tread is usually a variety of rubber or plastic compounds depending on the use of the belt specified.

Polyester Conveyor Belt

Types of conveyor belts

The steel cord conveyor belt is based on the ordinary steel cord conveyor belt, perpendicular to one or both sides of the longitudinal steel wire rope, horizontally and evenly laying steel ropes, steel cords, fiber ropes, fiber fabrics and other reinforcement layers to increase its horizontal tear resistance , Make it have good impact resistance and tear resistance.

Polyester conveyor belts,also called EP conveyor belts, whose tension resistant body is canvas woven by polyester in warp and nylon-66 in weft. The belts have the characteristics of low elongation in warp and good trough ability in weft, good water resistance, good wet strength, no mould, suitable for medium, long-distance and heavy-load transportation of materials. Because of the high initial modulus of polyester, the belts can choose a relative low safety factory.

Conveyor belts with nylon canvas inside have the characteristics of thin belt body, high tensile strength, good shock resistance, good trough ability, high adhesion between plies, splendid flexibility and long working life. Nylon conveyor belts are suitable for medium, long-distance and heavy-load transportation of materials.


If the belt system is carrying heavy loads, steel belts can be used because of their strength and durability. Steel belts are made from steel cord as opposed to lower strength belts using polyester, nylon and cotton.

The material used or the lower strength of the conveyor system installed will reduce the amount of energy consumed by the operation, while also extending product life and increasing productivity.

In the food industry you will see blue conveyor belts. This means that they can be washed, also known as washable, in order to comply with food hygiene laws.
