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.
