Haihui Environmental Protection Equipment Co., Ltd. manufactures belt conveyor steel carry trough rollers for heavy-duty material handling. These trough rollers support the loaded belt on the carrying side, forming a 35° or 45° trough angle to increase material cross-section and reduce spillage. Made from precision ERW steel tube with sealed bearings and multi-stage labyrinth seals, they resist dust and moisture ingress. Low rotational resistance minimizes belt friction and energy consumption. Each roller is tested for radial runout and rotation resistance before shipment. Suitable for mining, cement plants, ports, and aggregate handling, Haihui trough rollers provide long service life and reliable operation. Custom lengths and diameters are available to meet specific conveyor designs.
