Existing methods of belt conveyor calculations use high values of belt safety factors: from 8 to 10. This indicates the approximation of calculations, in particular, due to the fact that the dynamic forces in the belts arising at start-up (stopping) of conveyors are not taken into account. Taking into account the dynamics of belt tension is especially important for the calculation of multi-drive, long conveyors, where the drive stations are built into the inter-belt space and dispersed along the length of the conveyor. This would contribute to a more accurate selection of belt types and allow to obtain economic benefits from the installation of belts of lower strength or from the reduction of the drive slip time.
