Several disadvantages are associated with grain transportation, especially manual loading into trailers and silos. The need for a grain handling equipment became pertinent; hence, this study designed and fabricated a simple and medium size auger aimed at upward conveyance of grains into a silo. The conveyor was fabricated from local materials considering the physical properties of the selected grains, the techno-economic properties of the machine. The conveyor is powered by an electric motor through a V belt connection. Tests were run on the conveyor using common granular materials like maize, sorghum and gari at 13% moisture content. The angles of test considered were 0°, 15°, 30°, 45°, and 60° for each grain. It was found capable of loading an average size silo of 2.68 m 3 in 15 minutes. The conveyor has an efficiency of 99.95% and average output capacities of 407.05, 282.4 and 263.1 kg h-1 for maize, 450.2, 350.5, 263.0 kg h-1 for sorghum and 460.0, 365.3, 310.0 kg h-1 for gari at corresponding angles of inclination of 0°, 30° and 45° respectively. The conveyor is easy to operate with minimal technical know-how.
