The roller, a crucial component of the conveyor belt system, is available in various types and large numbers, and it serves to bear the load of both the conveyor belt and the materials it carries. It constitutes 35% of the overall expenditure of a conveyor belt system and is responsible for over 70% of the resistance encountered, hence the superiority of the drum's quality is of utmost importance. There are two primary materials used for drums: metallic and polymeric.
