635 mesh to micron: 20 µm (0.02 mm)
635 mesh is an opening of 20 microns, which is 0.02 mm or 0.000787 inch, on the ASTM E11 US standard sieve series. That is finer than the finest wedge wire slot we make, 25 microns (0.025 mm); ask us what suits a separation this fine.

Equivalent wedge wire slot: 20 micron (0.02 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.

What passes through 635 mesh
As a general reference on the Wentworth grade scale, particles smaller than 20 µm pass: clay. Real separation also depends on particle shape, the screen's open area and how the screen is loaded.
The wedge wire equivalent
That is finer than the finest wedge wire slot we make, 25 microns (0.025 mm); ask us what suits a separation this fine. 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.
