Conveyor belts are frequently blamed for belt tracking problems and in most cases this is unjustified. The failure cause is usually to be found in the installation itself and may be the result of poorly adjusted pulleys and rollers, incorrect application of belt tracking measures or faulty design.

The wrap angle must be sufiecient to transmit the belt conveyor forces to the driving drum. This in combination with the other parameters, such as pre-tension and friction. Therefore the belt conveyor has to be fully designed first and then the drive can be calculated. The wrap angle itself is limited by the structural design of the drive.

Minimum wrap angle is a measure of how much the belt wraps around the smallest pulley. Belt length is how long the belt would be if cut and laid flat. Finally, in the case of toothed belts (also called synchronous belts) the pitch is the number of teeth per some length—so a 3-mm pitch means that the belt has one tooth every 3 mm, for example.
