Structure of a conveyor belt

Structure of a conveyor belt

Belts consist of one or more layers of material. It’s common for belts to have three layers: a top cover, a carcass, and a bottom cover. However, there are situations where more layers are needed depending on the goods being moved on the conveyor system.

The purpose of the carcass is to provide strength and shape to the conveyor system and is often a woven or metal fabric having a warp & weft.

The warp refers to longitudinal cords and defines the running properties of the belt due to it being responsible for the level of resistance and elasticity of the belt.

The weft represents the whole set of transversal cables allowing the belt to be resistant to cuts, tears, and impacts while also being highly flexible to ensure the system doesn’t break easily.

The most common carcass materials to be used are steel, polyester, nylon, cotton, and aramid while the covers are usually various rubber or plastic compounds specified by the use of the belt.

If the conveyor system is carrying heavy goods, steel conveyor belts can be used due to their high strength and increased durability. The steel conveyor belts are made of steel cords compared to lower class strength conveyor belts that use polyester, nylon, and cotton.

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