How is the pulley diameter affecting the selection of conveyor belt?

The smallest conveyor pulley diameter the belt will encounter in the conveyor system is a primary consideration in selecting the proper conveyor belt. It is important that as the belt wraps around that pulley, under tension, the stress in the belt is below the fatigue limit of the bond between the belt components.

Overstressing the belt, particularly the bond between the individual plies and the skim, can result in ply separation and premature belt failure, especially at the belt splices. In some applications, due to system limitations, smaller than recommended pulleys may be used.

This will affect the service life of the conveyor belt and will result in more frequent splice replacements. A given belt construction has a characteristic "flexibility" in the lengthwise direction. Our brochures and data sheets give recommendations based on calculated tension at the pulley location.
