Haihui Environmental Protection Equipment Co., Ltd. manufactures supporting roller groups and centering roller groups for belt conveyor systems. Supporting roller groups consist of a stationary steel bracket and rotating idler rollers. These groups are installed along the conveyor frame to support the belt and reduce sag. The upper roller group carries the loaded belt on the top branch, while the lower roller group supports the empty belt on the return branch.

Centering roller groups are designed to automatically correct belt misalignment. Each centering group includes a pivoting frame and guide rollers. When the belt drifts off center, it contacts the guide rollers, causing the frame to pivot. This pivoting action generates a lateral steering force that pushes the belt back to the proper tracking path. Centering groups are typically placed every 10 to 15 groups on the carrying side and every 6 to 10 groups on the return side.

All roller groups are constructed from high-strength steel with sealed bearings and multi-stage labyrinth seals to block dust and moisture. Proper alignment reduces belt edge wear, prevents material spillage, and minimizes unplanned downtime. Surface treatment options include painting, electro-galvanizing, and hot-dip galvanizing for corrosion resistance. Custom sizes, trough angles (20°, 35°, or 45°), and bolt hole patterns are available. Trust Haihui for durable, reliable roller groups that extend belt service life.
