Haihui Environmental Protection Equipment Co., Ltd. manufactures high-quality supporting roller groups for belt conveyors. Each group consists of stationary brackets and rotating idler rollers. Upper roller groups support the carrying belt and material load, typically with three rollers forming a trough shape. Lower roller groups support the return belt using single flat rollers or V-shaped designs. Centering roller groups automatically correct belt misalignment by pivoting when the belt drifts off center, generating a force that guides it back. All rollers feature sealed bearings to block dust and moisture. Haihui roller groups reduce belt wear, prevent spillage, and improve conveyor efficiency. Suitable for mining, cement, and aggregate applications. Custom sizes available.
