DESIGN AND FABRICATION OF A SCREW CONVEYOR CIGR Journal
Olanrewaju, Taofiq Olayinka.
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...

Mathematical Model of a Dynamic Process of Transporting a Bulk Material by Means of a Tube Scraping Conveyor CIGR Journal
Lyashuk, Oleh Leontiyovych; Vovk, Yuriy Yaroslavovych; Sokil, Bohdan; Klendii, Volodymyr; Ivasechko, Roman; Dovbush, Taras.
The results of theoretical studies of simultaneous transporting  the components of feed mixtures along the curvilinear paths of tubular conveyors are presented in this article. The mathematical model of a technological process of moving a bulk material (grain) by means of a cable with a connected scraper is proposed. The model is presented as a system of elastic one-dimensional bodies, which are seamlessly moved by a bulk material. Nonlinear differential equations with partial derivatives that describe the dynamics of horizontal and vertical lines of a tube conveyor under the corresponding boundary conditions are deduced. Based on researches, the technique of determining the technological parameters, which ensure the reduction of energy consumption while...
