1. What is a roller?
The roller, a critical component of belt conveyors, comes in various types and large quantities, supporting both the conveyor belt and material weight. It accounts for 35% of the total cost of a belt conveyor and generates over 70% of operational resistance, making roller quality paramount. Materials include steel and plastic.
For Track rollers and Carrier rollers, available materials are 40Mn2, 40MnB, 50Mn (selected by working conditions). Through precision forging and normalizing before overall heat treatment, they achieve HRC52-60 surface hardness and a 7-10mm hardened layer depth (HRC45), ensuring high impact resistance and surface wear durability. Equipped with high-quality floating seals and lubrication systems, they operate in extreme climates (-45℃~120℃) with zero maintenance requirements.
