Abstract


Grain must be transported from one location to another. 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 conveying grains upward into a silo. The conveyor was fabricated from pure local materials considering the techno – economic properties. Tests were run on the conveyor using granular materials like maize, sorghum and gari at 13% moisture content. The angles of test were 00, 150, 300, 450, and 600 for each grain. It was found capable of loading an average size silo of 2.68 m3 in 15 minutes. The conveyor has an efficiency of 99.95%, and average output capacities of 407.1, 282.4 and 263.1kg/hr. for 0o, 30o and 45o respectively. The conveyor is easy to operate with minimal technical know-how.
