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.

1. Long Service Life - Our plastic roller is strived for perfection while choosing and processing the raw materials, and it is corrosion resistant, dustproof and waterproof and under equal conditions, the service time of the roller is 2-3 times longer than that of common rollers.

2. Energy Saving - The weight of the plastic roller is around one seventh of that of metal roller. It consumes less electricity than other heavier rollers. A 50-meter long conveyor belt that uses our plastic rollers, for instance, can save electricity fare worth 3,000 to 30,000 RMB annually.

3.Capable of Extending the Life Span of the Conveyor Belt - The plastic roller has low friction coefficient, excellent self-lubricating property and a smooth surface. Even if one roller breaks down, it won't pull, tear or damage the expensive conveyor belt and therefore can extend the life span of the belt.

4. Easy Installation - Plastic roller is light and therefore can be easily installed by just one person. Also it usually needs no maintenance as it has a low damage rate.
