conveyor belt sag between idlers

A belt tension that is too high pulls and stretches the conveyor belt, preventing it from troughing properly and therefore making it unable to contain material as well. if belt tension is too low, the belt will sag between idlers, allowing material to fall off the sides. these issues are resolved by properly tensioning the belt. reduce belt load.

Belt Conveyor Idler Spacing Affects Performance | Martin

Normally, idlers are placed close enough to support a fully loaded belt so it will not sag excessively between them. if the belt is allowed too much sag, the load shifts as it is carried up and over each idler and down into the valley between. this shifting of the belt increases belt wear and power consumption.
