Protecting Your Conveyor Belts from Sharp-Edged Materials
Impact damage is a more aggressive form of wear that affects conveyor belts, characterized by the damage caused by sharp-edged materials cutting or gouging the belt surface. This type of abrasion can significantly reduce the lifespan of a conveyor belt if not properly managed.
To measure the extent of impact damage, manufacturers use tests like the Pico Abrasion Test (ASTM Test Method D2228). In this test, tungsten carbide knives abrade a small sample of the belt cover. The sample is weighed before and after the procedure, and the weight loss is calculated. Results are presented as an index, with higher numbers indicating better abrasion resistance.
Preventing impact damage involves using materials that can withstand sharp and abrasive substances and implementing regular maintenance routines to monitor belt condition. Selecting the appropriate belt cover for the specific material being transported is crucial to minimizing the impact and extending belt life.
