The project aimed to (1) design and develop the machine, (2) construct and assemble its components, and (3) test and evaluate its technical performance in terms of throughput capacity and efficiency. The research utilized a developmental project design involving planning, fabrication, testing, and improvement phases. This research provides an insight into the importance of innovation, concerning a common machine used in Grain milling that aims to attain economic feasibility. The study utilized a differentiation approach, through a simple comparison to the other milling machines available in the market. After a successful fabrication of the machine, the findings reveal that owning one machine that is capable of milling three different grains, is better than owning three different milling machines that mills a different grain each.xi, 66 p.: ill (col).enGrain milling machineryGrain processing equipmentMilling machinesReplaceable bladesAgricultural machineryAgricultural machineryGrain—GrindingGrain milling machineryAgricultural machineryCutting toolsThesis
