It is possible to calculate an approximate mesh opening size for plane weave mesh with square openings. Both the wire or strand diameter and the distance between the centers of two adjoining strands must be known to do this. Filter mesh manufacturers provide the mesh opening size or the meshs percent of open area or both.

It could be 1 micron and qualify as -325 mesh, it could even be sub-micron and meet the -325 mesh specification. The designation -325 mesh is simply saying the powder passed through a 325 mesh screen. If you needed a powder that was closer to size you would need to specify two mesh sizes. For example Tantalum Powder, -40100 Mesh, 3N8 Purity

The mesh refers to the screen size. For example, a 12 inch mesh is about 4 holes per square inch a 14 inch mesh has about 16 holes per square inch 18 inch contains about 64 holes per square inch and so on. 1100 inch is the smallest mesh that is commonly used for microscopic gold recovery and ultra fine gold dust and flakes.

Feb 15, 2015 12 February 2015 0510 pm. sorry if i seem a little ignorant ..is anyone out there good at mesh sizes on sieves ..i have a keene sieve listed at 50 mesh however i need a much smaller mesh ...there is one on ebay 1100 of an inch ..mot sure how that compares with what i have .i have been googling trying to compare sizes but no luck
May 15, 2002 If that is the case for 3460 mesh size that would be material with particles going through a 60 mesh 250m sieve but not through 34 mesh 500m sieve, while 40100 would be 425 to 150m . respectively. The particle size itself will be slightly higher than the grade because grading is based on square mesh.
than the mesh size, a significant portion of near size material will be suspended above the big rocks on the wirecloth and have no chance of passing through an opening. The V factor is an attempt at determining the likelihood of near size materials reaching the wirecloth to be screened. Figure 5 shows the percent retained as a measure of

A -6 mesh powder contains particles that pass through a 6 mesh screen. A -6 mesh powder has particles that measure less than 3360 microns. A powder that is -325 mesh has particles that measure less than 44 micron. As you can see, the larger the mesh number the smaller the particle size of the powder. 16 Mesh.
What does mesh size mean Mesh size usually is referring to the mesh number a US measurement standard and its relationship to the size of the openings in the mesh and thus the size of particles that can pass through these openings. Figuring out the mesh number is simple. All you do is count the number of openings in one linear inch of screen.
Figuring out mesh sizes is simple. All you do is count the number of openings in a one US inch of screen. The number of openings is the mesh size. So a 4-mesh screen means there are four little squares across one linear inch of screen. A 100-mesh screen has 100 openings, and so on. As the number describing the mesh size increases, the size of the particles decreases.
Generally US Mesh is measured using screens down to a 325 mesh 325 openings in one square inch. Sometimes the mesh size of a product in noted with either a minus - or plus sign. These signs indicate that the particles are either all smaller than - or all larger than the mesh size.
Mesh size is a term often used by gold miners and gold dealers to indicate gold size. It refers to the mesh number a US measurement standard and its relationship to the size of the openings in the mesh screen sieve, and thus the size of particles that can pass through these sieve openings. Figuring out the mesh number is simple.
