flour machinery The principles of steel structure and ground sifter structure milling machinery are similar. Only the whole structure is different .For the ground sifter, its sifter is placed on the same level with roller mill, and for the steel structure, its sifter is set up on the upper of mill, that is to say ,the stocks pass through the sifter, and slide into mill instead of sucking by blower with pipes to decrease the power consumption, at the same time easy to control the machine. Considering the limited capacity of extractor, our company has developed and manufactured sifter classification milling machinery which adopts excellent bearing mill, patent right aluminum sifter screen, steel support frame, the technique art flow is the same as large-sized flour factory, thus the flour quality is the same as or better than that got from large-sized flour factory. The steel structure milling machinery with compact structure, excellent appearance, convenient installation and operation, little cost, high efficiency, is the preferred milling machinery for the buyer.
