A rice/maize mill machine is a mechanical device designed to process harvested grains by separating the outer coverings and grinding the kernels into consumable forms. The machine works by feeding dried rice or maize into a hopper, where the grains pass through rotating rollers, blades, or grinding plates that remove husks, bran layers, or crush the kernels. The processed product is then discharged through an outlet as clean rice grains or finely ground maize flour, while the husks and bran are expelled separately.
