Abstract
This paper presents the development of computer model for predicting the performance of vibrating conveyors with reciprocating circular or elliptical vibrating excitation.Experimental validation of the computer model for the reciprocating conveyor was carried out.The computer model takes into consideration all the three possible modes of motion (i.e.the throw mode, slide mode and stationary mode) and the transitions from one mode to another.It is based on a single particle mass analysis but using bulk material properties as the input parameters.The predicted results are presented in non-dimensional plots.An experiemental reciprocating vibrating conveyor with variable amplitude and frequency was constructed and tested with padi-rice and wet coal.Agreements between the theoretical and experimental results are good.Contour graphs derived from the non-dimensional plots of the reciprocating vibrating conveyor are also presented for design applications.
