Solution of Problems of Return Rollers

Fig.1 Fig.2 Fig.3


► Fig.1 This photo shows 2 flat return rolls with conveyor belt running far right (top roll) and conveyor belt running far left (bottom roll). The correct adjustments would be driving the end of the flat return roll forward as indicated.


►Fig.2 This example shows the approximate amount of sag on return rollers required for good tracking. Sag is regulated by the amount of weight placed on a counterweight take up or the amount of force applied to a screw take up. The take up serves four needs:

  1. Take up maintains slack side tension on conveyor belt to prevent slipping on drive pulley.
  2. Compensates for variations in the belt length resulting from belt stretch or shrinkage.
  3. Reduces excessive sag between troughing and return rollers.
  4. Take up provides live storage for extra belting which can be used for resplicing.

►Fig.3 This photo shows return rolls alternated over and under conveyor belt to assure good belt contact. Technique can be use concave curves where conveyor belt will lift off return rollers on return side (see next example). This technique may also be used on bowed conveyor belts which only contact return rolls on the very edges of the conveyor belt. This type of contact makes the conveyor belt impossible to train, but by neutralizing the bow. the conveyor belt can be trained.
