How to Determine Transition Distance - bulk-online Forums

2012-4-14  Hi guys, When you design an idler conveyor, how to determine the transition distance from terminal pulley to the last troughing idler for both drum and wing? In the book "belt conveyors for bulk materials", it recommended minimum transition distances from terminal pulley to the last troughing idler. But how can I make sure the belt will not skip the last troughing idler if it is too far from ...

2021-9-11  Conveyor Belt Transition Distance. The distance required for a belt’s transition varies with the amount of troughing required, the belt thickness, the construction of the belt, the type of carcass (steel cable or fabric) and the rated tension of the belt. A transition distance must be selected to provide at least the minimum distance
