Where Your Flour Comes From - Roller & Stone Milling ...

2020-3-31 · Just as stone mills are engraved, so are roller mills. These patterns help feed the grains through for optimal milling. A big difference though is for how long the wheat is in contact with the stones vs. rollers. In a stone mill the wheat has to pass through the two stones, starting at the center and coming out at the outer edge of the circle.
