Updated: Apr 29, 2021. Today's roller mills are an essential part of the American food production chain. Modern flour production depends on the use of grain roller mills to reduce wheat berries into flour. In addition, roller mills are vital to the processing of other grains, including the most important grain in the US today: corn.
