When we use GRAIN CLEANING MACHINE, cleaning is the evitable step. Cleaning always needs screening equipment. Screening utilizes mesh to separate impurities and the material. The material that cannot pass the screen mesh is called oversize product. And the material that can pass the screen mesh is called undersize product.
Sifter is the important component for the grain cleaning machine screening device. In actual production, one layer of sifter screening always cannot meet the technological requirement. Multi-layers of sifters screening is necessary. Therefore, the combination methods of grain cleaning machine sifter plays an important role in screening process. The sifter combination methods are divided into oversize product method, undersize product and mixing method.
Oversize product method: after continuous screening of the oversize product, we can get different undersize product. The small and large screen mesh size can classify the material into different granularity.
Undersize product method: after continuous screening of the undersize product, we can get oversize product with different granularity. In the same way, the small and large screen mesh size can classify the material into different granularity.
Mixing method: mixing method can mix the oversize products method and the undersize product method together and make the screen mesh have crossed allocation. The mixing method concludes the front two methods and is quite smart and can meet various screening equipment requirements. It is usually used in grain hulling and end products processing.
