HBA has installed a 200T/D wheat flour milling project in Mexico. Cleaning process adopts 1 sieving, 2 wheat scourings, 1 de-stoning, 3 air suctions, 2 magnet separatings and 2 dampenings; milling process adopts 5B7M1S1T and 2 bran scourings. The project has a simplified technical process, fewer machines and thus small investment. It applies to the medium hard and soft wheat with impurity content below 2% produced from Europe, North America, Oceania, North Africa, Middle East, إلخ. Positive pressure pneumatic conveying of the flour into silos can realize centralized packing and bulk distribution.
