Our flour milling solutions are mainly designed according to American wheat and Australian white hard wheat. When milling a single kind of wheat, the flour extraction rate is 76-79%, while the ash content is 0.54-0.62%. If two kinds of flour are produced, the flour extraction rate and ash content will be 45-50% and 0.42-0.54% for the F1 and 25-28% and 0.62-0.65% for the F2.
