12 mesh to micron: 1,700 µm (1.7 mm)
12 mesh is an opening of 1,700 microns, which is 1.7 mm or 0.0669 inch, on the ASTM E11 US standard sieve series. The nearest wedge wire equivalent is a 1,700 micron (1.7 mm) slot, because wedge wire is specified by its slot rather than a mesh count.

Equivalent wedge wire slot: 1,700 micron (1.7 mm)
Wedge wire is specified by its slot directly, so a wedge wire screen has no mesh count. Quote the slot in mm or microns.
Your inputs and results go into the quote form, so an engineer can check them against your operating conditions.

What passes through 12 mesh
As a general reference on the Wentworth grade scale, particles smaller than 1,700 µm pass: coarse sand, medium sand, fine sand, very fine sand, silt, clay. Real separation also depends on particle shape, the screen's open area and how the screen is loaded.
The wedge wire equivalent
A wedge wire screen is specified by its slot, so the equivalent is a 1,700 micron (1.7 mm) slot. Because the V-shaped wire widens behind the slot, particles that pass the face do not wedge in it. See mesh to micron and slot size and how to choose slot and open area.
