Transition distance of conveyor belt is traditionally defined as the distance from the center line of the first fully troughed idler roll to the center line of either the head pulley or tail pulley. It is a starting of belt conveyor machine.
SKE feels transition distance should be defined as the distance from the center line of the terminal conveyor pulley to the center line of the first effective conveyor idler which may or may not be the first fully troughed idler in the system. For example, a system having 45 degree idlers as the primary idlers set at the proper distance from the terminal pulley but having either 35 degree or 20 degree idlers too close to the terminal pulley would shift the emphasis from the 45 degree idlers to the 35 or 20 degree idler closer to the terminal pulley.
If you just consider the geometry of the situation, you will realize that the edge of the belt is being stretched since it is following the hypotenuse of a right triangle. The distance from the pulley to the top of the wing idler is certainly greater than the distance from the pulley to the center roll of the troughing set. If the transition distance is too short, the edge of the belt can be over-stretched. This will adversely affect the splices, load support and belt life.
