1. What is a roller?

The roller, a crucial component of belt conveyor systems, comes in various types and is available in large numbers. It bears the load of both the conveyor belt and the materials it carries. Representing 35% of the total expenses for a belt conveyor, the roller is responsible for generating over 70% of the resistance, making its quality a critical factor. Rollers are available in two primary materials: steel and plastic.
