Literature indicates availability of dynamic analysis of a drive shaft of a chain conveyor in a limited way. Relations for estimation of a conveyor chain pull to overcome, (i) Rolling resistance of the track, (ii) Tail sprocket and drive sprocket shaft bearing friction resistances, (iii) Drive and tail sprocket chain binding resistances and (iv) Impact loading on the chain have been only derived [1,2]. However, further extension to deduce the load torque demand on drive sprocket during one articulation of the chain is not seen derived in the literature. This paper details this, followed by digital computer simulation including illustration of application of this new procedure to a representative case study. Work on the same lines is not much seen in the literature. However, similar work by Harrison [4] is done for the belt conveyor.
