**Sieve: the relationship between (mesh-aperture-wire diameter)**

The relationship between them is very simple, first look at the picture, then understand the definition, I will give another example, and you can easily understand the relationship between them.

## Metal braided mesh

As can be seen from the picture, the metal woven mesh is woven with metal wires, and the mesh is square.

### Definition

Sieve mesh number: The mesh number of the screen mesh refers to how many holes are arranged in a length of one inch (25.4mm), that is, the number of meshes. We refer to the screen mesh as A for short.

**Wire diameter: **The diameter of the mesh wires that make up the metal woven mesh. Let’s call it B for short.

**Aperture: **The length or width of a square mesh. We call it C for short

Then the relationship between the three of them is A=B+C. The three of them are like this.

Now the problem comes, according to the definition of mesh size, it is only determined that A, B, and C are not clearly defined. But what determines the particle size of the powder passing through the sieve is the aperture (C), for example: when A is 50 mesh: B (0.122mm) + C (0.3mm) = A (50 mesh), and B (0.14mm) + C(0.28mm)＝A(50 mesh)

Therefore, if you have high requirements on the particle size of the sieve when purchasing a vibrating screen or accessories related to the sieve, please directly say the aperture (C), which is the most accurate and can determine the particle size of the sieve, B (Wire Diameter) What he determines is the thickness of the wire of the metal woven screen.

B (wire diameter) is large so that A remains unchanged, and C (aperture diameter) will be smaller. Such screens usually have a longer service life,

B (wire diameter) is small so that A remains unchanged, and C (aperture diameter) will be larger. This screen usually has a higher screening efficiency.

Usually, we prefer customer diameter to tell us the aperture (C), which is more accurate.
