Abstract: The detailed design procedure for a hammermill machine is presented. The system designed is a modification to the conventional hammer mill with a circular bottom casing and a semi-circular screen. The major problems associated with the conventional machine are longer milling time and low efficiency as a result of the material moving alongside the circular screen. This led to the design and fabrication of a modified hammermill machine with a flat screen. The hammer mill is a power mill making use of a high-speed rotating disc, which is stationary to a number of hammer bars that move superficially by a centrifugal force. The machine was made effective with a one horsepower electric motor, and the efficiency was found to be 92.9% after testing was done with dried maize.
