Sag Calculation In Conveyors Belt

Conveyor Belt Calculations - Brighthub Engineering

Oct 13, 2014· Some sag is good, even required, to keep your conveyor running smoothly. The weight of the sagging chain creates back tension on the rest of the belts, keeping the sprocket teeth engaged with the slats and keeping the conveyor in its wearstrip guides. Over time, however, modular belt links and table top slats will stretch.

Tension in Conveyor Belt due to weight placed on it ...

Jun 16, 2015· A couple of things: 1. A conveyor belt that is allowed to sag is not being properly supported. They should never be allowed to sag. 2. Even if it did sag, that has nothing to do with the power needed to make it run because the sag tension is a constant force that is equal everywhere and is static: it exists whether the belt is moving or not and isn't affected by the motion.
