Steel cord conveyor belts - Metso

Reinforcement properties

You can find more information on our web, so please take a look.

Made of high-tensile steel cords and various cover grades (see below). A typical carcass with 7 x 7 hot-galvanised steel cords provides a tensile strength of up to 2,000 N/mm. Also available as 7 x 19 for higher tensile strength (10 000 N/mm).

Standard cords have an elongation of 0.22 - 0.28%. High structural strength and pull-out strength ensure good resistance against fatigue. The open cross-lay design of the cords and the chemical adhesive system ensure that the core rubber penetrates thoroughly, bonds well and protects against corrosion for long-term integrity.

Cover grades

The belts come with various cover grades, all made of high-quality rubber with extremely high resistance to abrasion, cutting and impact and with excellent ageing properties. The choice of cover grade will depend on the application and will also determine the working life of the belt. Matching the right belt to your application means generating less waste in the long run — helping you to reach your sustainability targets.

Wear-resistant

Available in X, Y, W grades (and similar) for heavy-wear conveying applications such as bulky, sharp materials like heavy, abrasive rocks. High-quality cover grades are recommended to offer the best protection to the belt carcass.

Heat-resistant

Different types of grades are available for high-temperature applications (T120 and T200) such as clinker, coke, foundry sand and slag. Can be used for transporting material at continuous temperatures of up to 190 °C, with peaks of up to 200 °C

Flame-resistant

Available in flame-resistant grade K to comply with ISO 340. Can be used in tunnel projects but not underground applications.

STRUCTURE

Steel cable rubber conveyor belts are commonly used for transport of products at lengthy ranges and heavy loads which have high resistance. The steel cable conveyor belts are used also in high-speed transport at brief distances. These conveyor belts need only a very short take-up stroke.

The belt structure with its longitudinally ordered steel cables skeleton is resistant to fatigue because of flexing.

Thus, smaller diameter drive pulleys can be used to design equipment of smaller size. The steel wires are bonded with high level of adhesion to the fabric on their ground.

The rubber of the rubber conveyor belt with steel wires is therefore firmly attached to the steel cables and shockproof, enhancing the belt life. Steel cables are structured uniformly and have the same strain, which makes the belt upright and functional.

As the carcass doesn't have longitudinal yarns, the steel wire rubber conveyor belt carry more stuff within greater inclination.
