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.
The paper deals with the dynamics of braking devices, which may include, friction braking mechanism, clutch mechanism at the slip stage and some other.
