The right screening solution depends on the target mesh size, powder characteristics, required capacity, and how the material behaves on the screen.<\/p>\n\n\n\n As the mesh becomes finer, the screen openings become smaller and powder is more difficult to pass through. For 200\u2013500 mesh powder screening, the main problems are mesh blinding, particle adhesion, static, and lower throughput. These problems are more common with fine, light, or cohesive powders.For a broader comparison, see our ultrasonic vs traditional vibrating screen<\/a><\/strong> guide.<\/p>\n\n\n\n Fine particles can stick to the screen surface or become trapped in the mesh openings. Near-size particles may also block the apertures during continuous screening. This reduces the open screening area and makes fine mesh screening less efficient.<\/p>\n\n\n\n Ultra-fine powder can build up static or form small agglomerates during screening. Metal powder, graphite, and some chemical powders are more likely to have these problems. The particles may stick together or to the mesh instead of passing through it.<\/p>\n\n\n\n Screening capacity usually becomes harder to maintain as the mesh becomes finer. A 400 or 500 mesh screen has much smaller openings than a 200 mesh screen, so powder passes through more slowly. Actual throughput also depends on particle size, bulk density, flowability, feed rate, and screen diameter.<\/p>\n\n\n![\"criblage](\"https:\/\/yuanjingmachinery.com\/wp-content\/uploads\/2026\/09\/1-1.webp\")
