Research and design calculation of belt conveyor with midway driving technique on pulley unloading

摘要

This paper analyses the mechaniscs of the technique of pulley unloading midway dirving and belt's tensile stress varying law of the conveyor with this driving devices, gives the designing preconditions, steps and simple formulas of belt conveyor with midway driving devices, points out the applicable condition of thies device. This paper also introduces the advantages of this technique and an example.
