2 Small mills in Africa Largerscale mills are in operation in most African countries today. They mainly supply flour to larger cities and towns. These mills use fluted roller mills that operate to a higher technical standard than smallscale mills do. They can remove bran and wheatgerm, producing refined white flour mainly for bread making.
