Do you want to know the differences between the Wedge Wire Screen and the Woven Wire Mesh?
Which kind of screens is suitable for you? Let’s see as below points.
Durability
When it comes to durability, wedge wire is inherently more durable due to the fact that it is made up of heavier wire & components than the finer specifications of woven wire mesh would be.
However, woven wire mesh itself may not be as durable but it can be made to be as strong as necessary through additional processes like laminating into multiple layers or by combining it with an additional support or protection structure.
In the bigger world of filtration, both wedge wire and woven wire mesh are go-to types of filter media when the filter is exposed to harsh environments.
Mesh Size/Micron Rating
The mesh size or micron rating of wedge wire typically goes down to about 30 micron (.030mm).
Woven wire mesh can be produced that has a micron rating of 5 micron.
If very fine metallic filtration that maintains acceptable flow is required, woven wire mesh will have the edge in this situation. The woven material allows for precise control over opening sizes that can’t even be seen by the naked eye.
On the other end of the spectrum, either material can be made with openings as large as necessary. Both types of media can be made with accurate openings, so both can provide very accurate filtration it depends on what your needs are in terms of mesh size.
Cleanability
Both woven wire mesh and wedge wire and typically used as “surface filtration”, meaning that the filter cake, or buildup of material, being filtered from a liquid resides on the surface of the filter. This allows the filter to be easily cleaned and reused.
While both types of media are cleanable and reusable, wedge wire usually proves to be more easily cleaned due to a surface structure that is a bit smoother than woven wire mesh. There is also a bit less risk of damaging the material when cleaning with wedge wire than with woven wire.
Life Span
Life span could refer to how long a filter can run between cleanings, how many times can that filter be cleaned, and how long will the filter last in the conditions where it operates.
Wedge wire is typically more robust and can sometimes be cleaned easier, so these filters will typically have a longer service life.
The more delicate nature and finer wires within woven wire mesh could lead to a shorter service life when compared to wedge wire. Woven wire can still be cleaned and maintained but there is a higher risk of wear and tear. The wedge wire will simply hold up to more abuse for a longer period of time.
