How long does an abrasion resistant plate last in ports and grain terminals?

The short answer: a properly specified cast abrasion-resistant steel plate withstands the passage of more than 100 million tons of grain or pellet before it wears out. But the real service life is not a fixed number — it depends on the working conditions of each installation.

Three variables define the service life: the abrasiveness of the cargo (a compacted pellet is more aggressive than a whole grain), the angle at which the material strikes the surface, and the speed at which it moves. The greater the impact and speed, the greater the wear. That is why the same plate can last far longer in a smooth-flow chute than in an elevator head under constant impact.

Wear is gradual: the plate loses thickness evenly until, near its limit, it loses mechanical strength and can break through fatigue or bending. The important thing is to replace it before that point — and because the system is modular and bolted, only the worn plate is changed, without touching the structure.
