The major objective of the present research work is to determine the filling factor of dry coarse sand in a short length screw conveyor while using Ribbon type of screw at different screw speeds, and to investigate whether this filling factor is dependent on screw speed or not along with the variation of filling factor at two different trough height is also investigated. Another objective is to study the effect of two different constant trough heights from centre of screw shaft on filling factor for a short length screw conveyor with flood-feeding condition. However the experiment is conducted with a particular type of screw (ribbon type) at various speeds.

Keywords: Conveyor, flood-feeding condition, filling factor, ribbon type screw.
