60 mesh to micron: 250 µm (0.25 mm)
60 mesh is an opening of 250 microns, which is 0.25 mm or 0.00984 inch, on the ASTM E11 US standard sieve series. The nearest wedge wire equivalent is a 250 micron (0.25 mm) slot, because wedge wire is specified by its slot rather than a mesh count.

Equivalent wedge wire slot: 250 micron (0.25 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 60 mesh
As a general reference on the Wentworth grade scale, particles smaller than 250 µm pass: 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 250 micron (0.25 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.
