The hammer mill was designed and constructed from locally available materials for grinding grain particles such as maize, millet, guinea corn and other coarse materials of cassava tuber, yam tuber, beans, etc. into small size enough to pass through the holes of the cylindrical sieve positioned beneath the hammer assembly. The grinding process is achieved by the use of a hammer in beating the ...
