Extrusion Screen Pack Mesh Sizes
Thus a breaker-plate mounted screen pack consisting of more than one screen mesh (for example, a stack consisting of 20/60/150/20 mesh sizes) is often inserted into the melt stream to remove contaminants. An example of such a screen pack is shown in Figure 2.
A 20-mesh screen is typically used for the outside of the pack and can support up to a 150-mesh screen, depending on the extrusion pressures. Finer screens will need an additional support screen to avoid screen "blowout," which is where the wires separate under pressure, allowing larger particles to get through. Packs can be spot welded ...
May 25, 2015· FILTRATION MESH Every processor wants the best filtration they can get for the area of filtration they have. Very few, however, utilize a screen-pack configuration fully optimized for their process. Take as an example a situation in which an operator is attempting to extend a production run between screen changes.

The use of a screen pack is recommended for the extrusion of EVAL™ resins. The screen pack mesh should be based on commercial polymer extrusion knowledge and common sense. Examples of typical combinations of stainless steel meshes are: 50/100/50/50, 50/100/150/100 or 80/150/50/50. The typical distance between the screw-tip and the screen pack ...
In most extrusions, though, a screen pack is used, which is made up of several screens: a 20 mesh (20 wires per inch) is put up against the breaker plate, then perhaps a 40 mesh. In case of extreme levels of filtration required, an 80 mesh is used after the 40 mesh.
