A flour powder rotary vibrating screen can be used for different screening tasks, so the right equipment depends on what the flour needs to be screened for. Some production lines only need to remove lumps and impurities, while others need to screen flour more finely or separate flour into different size ranges.<\/p>\n\n\n\n
Before choosing the equipment, first determine what needs to be removed and how fine the flour needs to be. Then look at the screen, capacity, number of screen layers, and equipment size.<\/p>\n\n\n\n
There are three common situations.<\/p>\n\n\n\n
Flour may form lumps during storage and conveying, and larger impurities may also enter the material. In this case, the qualified flour passes through the screen while lumps and larger particles are retained on the screen. If this is the only screening task, one screen layer is usually enough.<\/p>\n\n\n\n
In this case, the screen opening is important. The smaller the screen opening, the finer the particles that can pass through, but the flour will also pass through the screen more slowly. If the flour tends to form lumps, a very fine screen opening may also increase the risk of screen clogging. So you should not only look at the mesh size, but also consider how fine the flour needs to be. For test sieve specifications, see ISO 3310-1<\/a><\/mark><\/strong>.<\/p>\n\n\n\n This requires different screen layers to separate the material. For example, two screen layers can separate flour into different size ranges. If the only purpose is to remove lumps and impurities, there is no need to add multiple screen layers. The more screen layers there are, the more complex cleaning and maintenance will be.<\/p>\n\n\nThe third is separating flour into different size ranges.<\/h3>\n\n\n\n
