1. What is a roller?

Rollers play a critical role in belt conveyor systems. These components come in a wide variety of types and are deployed in large quantities. Their primary functions include supporting both the conveyor belt itself and the transported materials' weight. Significantly, rollers account for approximately 35% of the total cost in a belt conveyor setup. Additionally, they generate over 70% of the operational resistance during system operation, underscoring the vital importance of roller quality. Modern roller designs are typically constructed from two primary materials: steel and plastic.
