The number of transition idlers depends on the trough angle of the conveyor In the case of a 45 degree trough angle 2 or 3 transition idler sets would be used at either end of the conveyor These idler sets would have incrementally greater trough angles of say 15 20 and 35 degrees through the transition zone leading up to 45 degrees

Carrying idler training the belt with the troughing idlers is accomplished in two ways shifting the idler axis with respect to the path of the belt commonly known as quotknocking idlersquot is effective where the entire belt runs to one side along some portion of the conveyor or radial stacker
The belt and the idler rolls can be calculated by using the multiplying factor k x k x is a force in lbsft of conveyor length to rotate the idler rolls carrying and return and to cover the sliding resistance of the belt on the idler rolls the k x value required to rotate the idlers is calculated using equation 3
Trough idlers trough idlers are the most common type of carry idler which are typically designed with 3 or 5 idler rollers and are fitted to the carryside of the conveyor belt the 5roll idler offers more uniform cross section resulting in a greater net carrying capacity the 3roll design has a centre idler roll and wing idlers on either side
