Abstract
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.
