How Many Meshes does 1 Micron Correspond to in Powder Sieving?

How many meshes does 1 micron correspond to in powder sieving?
The answer is that 1 micron equals to 12500 mesh.
 
Mesh and micron are mesh units. Mesh is also a unit that represents the size characteristics of particle materials. Mesh number is the number of hundreds of mesh in one inch (25.4mm), and micron is the unit of mesh aperture.
 
The formula is: aperture (μm) = 25.4 / mesh - wire diameter
For example, 325 mesh stainless steel screen, wire diameter 0.030mm
Then, the aperture of 325 mesh screen = 2.54 / 325-0.030 = 0.048mm = 48 μm
 
Micron and purpose conversion process:
Unit of measurement grain size refers to the size of raw material particles, generally expressed by the maximum length of particles.
 
Mesh refers to the size of the mesh size of the standard sieve.
In the Taylor standard sieve, the mesh is the number of holes in the length of 2.54 cm (1 inch), which is called mesh for short.
Finally, the diameter of the sieve (μm) is about 14832.4/mesh
 
Taylor standard sieve system:
The graduation of Taylor sieve system is based on the mesh size of 0.074mm,
Multiply or divide by the nth power of the root of the main modulus (1.141) (n = 1, 2, 3...) , and a larger or smaller mesh size of 200 is obtained.

If the square root of number 2 (1.1892) is multiplied or divided by 0.074mm,
We can get a series of sieve sizes with finer division.
 
So the larger the mesh, the finer the particles. Similar to the magnification of metallographic structure.
