The so-called mesh refers to the particle size or thickness of the material. The general definition refers to a screen within an area of 1 inch * 1 inch, and the material can pass through the screen, and the number of holes in the screen is defined as the number of meshes. For example, 200 meshes means that the material can pass through a screen with 200 meshes in 1 inch * 1 inch. By analogy, the larger the mesh number, the finer the material particle size; the smaller the mesh number, the larger the material particle size. The sieving particle size is the size of the sieve openings through which the particles can pass through the sieve.
The specifications of standard sieves in different countries are not the same. The commonly used Taylor system uses the number of holes per inch as the sieve number, which is called mesh. For example, a 100-mesh sieve means that there are 100 sieve holes per inch of the screen.
The mesh size corresponds to the standard mesh:
