Is the larger the mesh of the silica, the finer it is? Find the relationship between mesh size and particle size Mesh refers to the number of empty holes on the screen per square inch. 50 mesh means that there are 50 holes per square inch, and 500 mesh means 500 holes. The higher the mesh number, the more holes. In addition to indicating the holes of the screen, it is also used to indicate the particle size of the particles that can pass through the screen. The higher the mesh number, the smaller the particle size.
The following table is a comparison table of mesh number and particle size (μm) commonly used in my country.
