Anti-cutting
The cut-resistant compound is designed to reduce the risk of damage to the belt when carrying abrasive or sharp materials. The presence of specific additives such as high-strength polymers and reinforcing fillers helps create a harder surface that is resistant to mechanical damage. These components enable the belt to withstand impact and abrasion without compromising its structural integrity
To counteract problems arising from shear, one of the most effective solutions is the use of a reinforced rubber compound combined with the insertion of a metal breaker inside the tape.
As mentioned, the cut-resistant compound is designed to increase the rubber’s resistance to impact and abrasion. The addition of additives such as high-strength polymers and reinforcing fillers makes it possible to create a harder and stronger surface. However, in particularly heavy-duty applications, this solution may not be sufficient to completely prevent longitudinal shear, especially with extremely sharp or pointy materials.
The introduction of a metal breaker is a particularly effective solution to reinforce the conveyor belt and reduce the risk of longitudinal cuts. The metal breaker is an internal steel reinforcement, consisting of wire mesh or woven wires, which is integrated inside the belt rubber. This layer of metal reinforcement:
Increases the mechanical strength of the belt, preventing rubber failure when impacted by sharp objects.
It better distributes tensile forces, reducing the risk of tearing and longitudinal shear.
Prevents shear propagation: In case of surface damage, the metal breaker helps stop the expansion of the shear, maintaining the integrity of the tape.
Increases operating life: With this extra protection, the belt is able to last longer in harsh working conditions, reducing the need for frequent replacement.
In particular, the metal breaker is very useful in belts working in mining environments, where the presence of sharp rocks and abrasive materials is common. The combination of a high-strength rubber compound and metal reinforcement makes the belt much stronger and more resistant to impact, abrasion, and shear damage.
Cut and tear protection is essential to ensure the long life and reliability of conveyor belts, especially in high-stress industrial environments. The use of high-quality cut-resistant compounds, combined with the use of reinforcements such as metal breaker, is an optimal solution to prevent significant damage, reduce maintenance costs, and increase operational safety. As a result, conveyors can operate more efficiently, minimizing plant downtime and providing greater continuity in conveyor operations.
