Product Description Belt conveyors are a series of rollers supported within a frame where objects can be moved by power, our rollers are mainly used in Mining, Power Plant, Steel Plant, Cement Plant, Port and Recycling. Troughing rollers are an essential aspect of the mining industry. They support conveyor belts by positioning them toward a specific direction, minimizing the potential for deposits spilling over the belt and allowing the belt to hold more deposits.
