A 325 screen has 325 wires per inch.
325 mesh is the finest particle size that most ceramic minerals can be practically processed to.
This is a Mesh size that you see a lot, especially on kaolin data sheets. For example, you may be offered a “325 Mesh kaolin”.
325 mesh particle size is also commonly used in the following fields:
painting grade talc 325 mesh,
coatings 325 mesh
325 mesh Graphite
325 mesh Manganese oxide Mn2O3
Magnesium oxide 325 mesh
325 mesh Tin powder
325 mesh Lanthanum Oxide, Tantalum, Aluminum powder, quartz powder, nickel powder, etc.
A sieve with 325 wires/inch, the openings between the wires measure 44 microns.
| Mesh | Wire Dia. | Opening Width | % of Open Area | ||
| inch | mm | inch | mm | ||
| 325X325 | 0.0014 | 0.035 | 0.0017 | 0.044 | 30 |
Rolls with widths of 1 meter, 1.3 meters, and 1.5 meters and lengths of 30 meters 325 mesh wire mesh can be provided. They can also be cut into various shapes for 325 mesh sieve and 325 mesh filtration.
