When selecting a vibrating screen, mesh size and aperture (opening size) are two important screen specifications. Mesh size indicates the number of openings per inch of screen, while aperture refers to the actual opening size of each mesh opening.<\/p>\n\n\n\n
In general, the higher the mesh number, the smaller the aperture, and the finer the material that can be screened. However, mesh size and aperture do not have a strict one-to-one relationship because the actual aperture also depends on wire diameter and mesh specifications.If you want to understand how the sieve relates to the complete screening machine, see our guide to Sieve vs Sifter<\/a><\/mark><\/strong>.<\/p>\n\n\n\nVibrating Screen Mesh Size and Aperture Comparison Table<\/h2>\n\n\n\n

Note: The values above are commonly used reference values. Actual screen specifications may vary depending on the mesh specification and applicable standard. For reference, ISO 3310-1 <\/a><\/mark><\/strong>specifies technical requirements and testing methods for test sieves made of metal wire cloth. For final selection, use the required aperture size and material screening requirements as the main basis.<\/p>\n\n\n
