  • Conveyor belt transition distances vary by belt Martin

    The transition distance required is a function of the construction of a belt. When engineering a new conveyor, the belting should be selected to match the material load and conveyance length characteristics of the conveyor. The transition distance of the system would then be designed to match the requirements of the selected belting.
