GRAIN MILLING MACHINE. PAPER I: DESIGN AND CONSTRUCTION

A work was carried out on the design and construction of a motorized grain milling machine. The machine was designed using auto-CAD, version 2012 and constructed in the Department of Agricultural and Environmental Resources Engineering, University of Maiduguri in 2013. The machine consists of main components that include the frame, Petrol engine (Prime mover), Milling compartment and the hopper. The various compnents were designed and constructed according to specifications given in the literature. The components were assemblied together to obtain the required machine. The total cost of producing the machine was about N40, 000 only, equivalent to USD 160 as at June 2013. The machine is recommended for small holders, local processors, rural farmers and for domestic use. The performance efficiencies will be presented in the next paper.
