How does a wheat flour milling machine work? The core technologies of our group are in the filed of wheat flour milling process engineering, with European technology, China wheat flour milling process , roll out unique and innovative wheat flour milling processing line . It has the following features: wheat structure 1. Roller Mills Pneumatic roller mill 1)The partitioned paneling and swing-out feed module guarantee ideal    access to the feeding and grinding rolls . This makes residue-free     cleaning possible.    2) a pulse generator automatically adjust the feed material at the entrance door    3) bearing SKF    4) temperature monitor (option) 2. Roller :  roller Two different alloys with a mixing ratio allow the perfect balance                   to be achieved between hardness and roughness.  3 . Plansifter   high plan sifter       1) Material: High-strength alloy steel       2)up and down sifter circles with steel plate overal
