75 micron to mm: 0.075 mm

75 microns is 0.075 mm, or 0.00295 inch. As a sieve opening it is 200 mesh on the ASTM E11 series. For a wedge wire screen, specify it directly as a 75 micron (0.075 mm) slot.

Mesh sizes follow the ASTM E11 US standard sieve series. Between listed sieves the mesh is interpolated and marked "about".

Equivalent wedge wire slot: 75 micron (0.075 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 a 75 micron opening

As a general reference on the Wentworth grade scale, particles smaller than 75 µm pass: 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 75 micron (0.075 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.
