DESIGN AND FABRICATION

This study was undertaken to design and evaluate the performance of an electric motor-driven pellet mill intended for animal feed production. The developed pellet mill comprises several key components, including a feed hopper, pelleting chamber, pellet roll, die plate, and frame. It is powered by a 5 horsepower electric motor and operates utilizing a roll-type extrusion press to
expel the formulated feeds through the die plate. As the pellet rolls rotate, they apply pressure that facilitates the rearrangement of particles, thereby filling the voids of the die plate. During the compression phase, the pressure increases, prompting brittle particles to fracture and malleable particles to deform, which allows them to be processed through the die and emerge as pellets. The pellets subsequently fall due to the impact generated by the rotating die plate. This apparatus is capable of producing pellets with a diameter of 5 mm and a length of 25 mm. An investment of #323,000 is necessary for the procurement of the pellet mill and the construction of its housing. Financial analysis indicates that utilizing the CPU-CARES Formulated Starter Mash for pelleting feeds would be a profitable endeavor, yielding a rate of return of 423% on the capital invested. Furthermore, the benefits realized amount to 16% of the incurred costs, and the initial investment, inclusive of housing, can be recouped in less than three months. Based on these findings, the pellet mill has demonstrated its ability to transform dusty mashed feeds into pellets, producing a considerable quantity of pellets daily.

The increasing global demand for clean and sustainable energy has intensified the need for innovative solutions that harness renewable resources. This project explores the design and implementation of hybrid electricity generation system that integrates wind turbines and solar photovoltaic (PV) panels. By combining these two complementary energy sources gives an efficient means of power generation, particularly in regions with variable weather conditions. The wind turbine component captures kinetic energy from wind currents, while the solar panels convert sunlight into electrical energy. Together, they form a synergistic system capable of reducing dependence on fossil fuels, minimizing environmental impact, and enhancing energy security. The project also examines key technical aspects such as system configuration, energy storage, power conversion, and grid integration. Through simulation and analysis, the study demonstrates the feasibility and benefits of hybrid renewable energy system in meeting electricity demands sustainably. The motivation for developing a hybrid wind and solar power system stems from the growing need for sustainable and reliable energy
