The so-called mesh refers to the particle size or thickness of materials. The general definition refers to the screen within the area of 1 inch * 1 inch. The material can pass through the screen, and the number of holes of the screen is defined as the mesh number. For example, 200 mesh means that the material can pass through a screen with 200 meshes within 1 inch * 1 inch. By analogy, the larger the mesh number, the finer the particle size of the material; The smaller the mesh number, the larger the particle size of the material. The screening particle size is the size of the mesh through which particles can pass through the mesh, which is expressed by the number of mesh in the mesh with a width of 1 inch (25.4mm), so it is called mesh.
The specifications of standard sieves vary from country to country. The commonly used Taylor system takes 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 sieves per inch of screen mesh.
The mesh size corresponds to the standard mesh number:
Mesh size: 4.75mm standard mesh: 4 mesh
Mesh size: 4.00mm standard mesh: 5 mesh
Mesh size: 3.35mm standard mesh: 6 mesh
Mesh size: 2.80mm standard mesh: 7 mesh
Mesh size: 2.36mm standard mesh: 8 mesh
Sieve size: 2.00mm standard mesh: 10 mesh
Mesh size: 1.70mm standard mesh: 12 mesh
Mesh size: 1.40mm standard mesh: 14 mesh
Mesh size: 1.18mm standard mesh: 16 mesh
Mesh size: 1.00mm standard mesh: 18 mesh
Mesh size: 0.850mm standard mesh: 20 mesh
Mesh size: 0.710mm standard mesh: 25 mesh
Mesh size: 0.600mm standard mesh: 30 mesh
Mesh size: 0.500mm standard mesh: 35 mesh
Mesh size: 0.425mm standard mesh: 40 mesh
Mesh size: 0.355mm standard mesh: 45 mesh
Mesh size: 0.300mm standard mesh: 50 mesh
Mesh size: 0.250mm standard mesh: 60 mesh
Mesh size: 0.212mm standard mesh: 70 mesh
Mesh size: 0.180mm standard mesh: 80 mesh
Mesh size: 0.150mm standard mesh: 100 mesh
Mesh size: 0.125mm standard mesh: 120 mesh
Mesh size: 0.106mm standard mesh: 140 mesh
Mesh size: 0.090mm standard mesh: 170 mesh
Mesh size: 0.0750mm standard mesh: 200 mesh
Mesh size: 0.0630mm standard mesh: 230 mesh
Mesh size: 0.0530mm standard mesh: 270 mesh
Mesh size: 0.0450mm standard mesh: 325 mesh
Mesh size: 0.0374mm standard mesh: 400 mesh
A plus or minus sign in front of the mesh indicates whether the mesh of the mesh can be missed. A negative number indicates that the mesh can be missed, that is, the particle size is smaller than the mesh size; A positive number means that the mesh of this mesh cannot be missed, that is, the particle size is larger than the mesh size. For example, if the particles are -100 mesh to + 200 mesh, it means that these particles can leak through the 100 mesh but cannot leak through the 200 mesh. When screening the particles with this mesh number, the particles with a large mesh number (200) should be placed under the screen with a small mesh number (100), and the particles left in the screen with a large mesh number (200) are -100~ + 200 mesh.
