The three pertinent equations are: T0 = 4.20 Si (Wb + Wm) for 3% sag. T0 = 6.25 Si (Wb + Wm) for 2% sag. T0 = 8.40 Si (Wb + Wm) for 1.5% sag. In these equations, Si is idler spacing in feet, Wb is a weight per foot of the belt, and Wm is a weight per foot of the material. After calculating T 0 it is essential to add or subtract the weight of ...

The role of belt conveyor tensioning device: 1. Ensure that the conveyor belt is closely attached to the driving drum, so that its winding end has enough tension, so that the required traction can be transferred, so that the required friction between the drum and the belt, to prevent the conveyor belt from slipping. 2. Limit the tension of each …
