1. What is a roller?
The roller, serving as a crucial component in belt conveyors, is
available in various types and large quantities, and is capable of
sustaining the conveyor belt and the material's weight. It
comprises 35% of the overall cost of a belt conveyor, while
generating more than 70% of the resistance, making the quality of
the roller extremely significant. There are two main materials used
for rollers: steel and plastic.
