The mills missed a stage in the development of flour milling and remained the same until the introduction of the roller milling process and the desire by the American for Minneapolis style flour. The Early Mills:Design and Development of a Petrol-powered A conventional hammer mill is a device consisting of a rotating head with free- swinging hammers, which reduce rock, grains or similarly hard objects to a predetermined size through a perforated screen, hammer mills can be used for grinding grain into fine flour or into coarse meal for animal feed production. This project is focused on the design, development, and testing of a hammer mill that
