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.

Belt Conveyor Transfer Points - 911 Metallurgist

08/05/2019  In most conveyor installations, the troughed belt goes through a transition section onto a flat pulley. The time required must be short enough to prevent the material, originally contained in the trough from spilling over the edges of a flat belt. The transition period should not exceed one second. Especially with free flowing materials like iron ore pellets, the belt speed should be at least ...
