<\/figure>\n<\/div>\n\n\nWhy Does Wheat Flour Form Lumps and Blind the Screen? How Can These Problems Be Solved?<\/h2>\n\n\n\nWhat Should You Do If Wheat Flour Forms Lumps?<\/h3>\n\n\n\n
If wheat flour already contains lumps before entering the screen, first check whether the flour has absorbed moisture and whether storage conditions are appropriate.<\/p>\n\n\n

<\/figure>\n<\/div>\n\n\nA Rotationssieb<\/a><\/mark><\/strong> can retain lumps larger than the screen openings, but it cannot solve moisture-related problems. If there are many lumps, identify the cause and treat the material according to production requirements. If only a small number of lumps need to be removed, select the screen aperture based on the size of the particles to be retained.<\/p>\n\n\n\n Check three things first:<\/p>\n\n\n\n If the screen blinds again soon after cleaning, check whether the flour has absorbed moisture, whether the feed rate is excessive, and whether the screen aperture is appropriate. Only after ruling out these causes should you assess whether bouncing balls, brushes, or an ultrasonic screen cleaning system<\/a><\/mark><\/strong> are needed.<\/p>\n\n\n\n If larger particles that should have been retained end up in the undersize product, stop the machine and inspect the screen for damage, incorrect installation, and gaps between the screen mesh and frame that could allow material to bypass the screen.<\/p>\n\n\n\n If the screen is intact, check whether the aperture meets the screening requirements. If the openings are too large to retain the particles that need to be removed, confirm the correct screen specification.<\/p>\n\n\n\n First, check whether flour is accumulating on the screen surface or entering at one concentrated point. If the screen is blinded, follow the troubleshooting steps in the previous section.<\/p>\n\n\n\n If the feed is normal and the screen is not blocked, check whether the screen openings are too small and whether the effective screening area is sufficient.<\/p>\n\n\n\n Do not judge capacity only by the equipment diameter or the manufacturer’s stated maximum throughput. Actual capacity varies with screen specifications, material conditions, and screening requirements.<\/p>\n\n\n\n The main configuration factors are the screening objective, number of screen decks, and screen blinding conditions. For a broader overview of flour screening equipment, see our guide to the industrielle Mehlsiebmaschine<\/a><\/mark><\/strong>.<\/p>\n\n\n\n In addition to the housing material, pay attention to the components that contact the flour, how easily the equipment can be cleaned, and whether flour dust can escape at the feed and discharge points.<\/p>\n\n\nWhy Does the Screen Mesh Become Blinded?<\/h3>\n\n\n\n

If you need to separate flour into different particle size fractions, define the screening requirements first.<\/td> Do not rely on mesh count alone. Confirm the actual screen aperture.<\/td><\/tr> Number of screen decks<\/td> A single deck is generally sufficient for removing lumps or larger particles. Consider multiple decks when different flour particle size fractions need to be separated.<\/td> More decks make product discharge arrangements, cleaning, and screen replacement more complex.<\/td><\/tr> Screen cleaning system<\/td> Consider a screen cleaning system if blinding continues after normal adjustments.<\/td> Bouncing balls, brushes, and ultrasonic systems are designed for different screen structures.
