Belt Conveyor Idlers – IspatGuru

2021-9-25  Troughing idler spacing adjacent to terminal pulleys – In passing from the last troughing idler to the terminal pulley, the belt edges are stretched and tension is increased at the outer edges. If the belt edge stress exceeds the elastic limit of the carcass, then the belt edge is stretched permanently and causes belt training difficulties.
