Article Title: Design for Production of Single Flight Screw Worm from White Cast Iron Using Sand Casting Technique
by Oyetunji A. and Alao, Osheiza Alice

The design for production of single flight screw worm via sand casting using white cast iron was done. It takes into consideration the design aspect of engineering components coupled with its working drawings and principles, in this case, the screw worm and its application. The design entailed designed for shaft diameter, volume of material transfer per one revolution, factor of safety for live loading was designed, depth of the groove (both upper width and lower width) of the grooving) and speed of conveyor shaft pulley. The design limitation was equally stated and selections of the materials for the production of shaft were equally undertaken where mild steel shaft diameter was calculated to be 77 mm through design analysis which eventually determined the internal diameter of the screw worm conveyor. The pulverizing (grinding) machine system on which the conveyor would be employed would be powered by a prime mover (electric motor, petrol or diesel engine) of between 1 kw to 1.5 kw rating. The modest-choice of prime rating was based on considerations of cost, availability, and transportation weight savings of the power unit
