2020-6-12 Pipe belt conveyor is a new type of environmentally friendly and efficient bulk conveying equipment. In the design of the roller, the belt and the driving motor of pipe belt conveyor, the sag resistance is a key parameter. Meanwhile, the normal force between the conveyor belt and the roller group is the other important factor need be considered and has a great influence on the sag resistance.

Belt sag can be eliminated by correctly supporting the belt. For an effective, minimum-spillage transfer point, the belt line of travel must be stabilised with proper belt support in the conveyor’s loading zone. A flat, sag-free belt line in the skirted area is essential to successfully sealing the load zone.

Next it is important to calculate T2 sag (slack side tension required to prevent belt sag.) Sag is a phenomenon which can occur at the point of minimum tension in the carrying strand of a conveyor belt. On an inclined conveyor, it is usually in the vicinity of the

2014-10-10 Fig. 6: Belt sagging [28] An excessive sag in the belt results in a higher power consumption for the conveyor and therefore the pitch of the idlers in conjunction with the tension in the conveyor should ensure that the sag is limited to between 1,5% and 3%.[28] B. General concept of Design

side. This prevents excessive belt sag from the belt’s own weight. In standard conveyors for light materials handling, the conveyor belt runs over two end drums (in this case end and drive drums). The best configuration, called a head drive, is where the drive drum is at the end of the conveyor where the pro-ducts are discharged. In this case ...

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: Take up maintains slack side tension on conveyor belt to prevent slipping on drive pulley.
