The 8+2 sets of stone mill flour processing equipment have low rotation speed and low grinding temperature, which will not damage the nutrients in wheat. The equipment effectively improves the flour yield and is suitable for processing in large stone mill flour factories. The ground flour is natural flour, without any additives, with good taste and high nutritional value. Using stone mill flour can avoid the damage of high temperature and high pressure to the nutrition of flour during large-scale mechanical production, thus retaining more nutrients in the flour.
