Basic Information Of Extruder Screen 

 

The extruder screen is an important part of the extruder and can be filtered to produce a qualified product. The extruder screen is used for filtration and blending of various viscous materials and products in the production of plastics, chemical fiber, rubber, hot melt adhesives, adhesives, coating materials, and mixtures. The extruder filter has a mesh type and mesh belt type. The extruder can automatically replace the filter through the automatic screen changer. It saves time and labor, and product performance is stable. Filtration time reduces production costs.

 

Specification of the extruder screen

 

Material: SS304, 316, 316l

Mesh: 20~150 mesh

The mesh of most filters is a square weave, the number of wires in each direction is the same. The Dutch weaving method uses thick wire in the horizontal direction and is specified as a double number. For example, 32 x 120 roots/in (1 in = 25.4 mm). Filters made by the Dutch weaving method do not require a parallel screen in the filter unit to provide fine filtration.

 

The pore size of the filter mesh having the same number of mesh eyes is determined according to the diameter of the wire, and it is not necessary to be completely identical. For example, a 20-mesh filter made of wire with a line spacing of 24 inches and a diameter of 0.02 inches has an opening of 0.01 in each side; and a wire made of 30 in. and 0.01 in diameter. A 20 mesh screen with a slightly larger opening on each side of 0.04 in. This is because the fine wire is not sufficiently fine to filter and is more likely to clog (1 in = 25.4 mm).

In general, the filter unit is installed in such a way that the coarsest screen faces the protective sheet and the thinnest screen faces the extruder. For example, the filter arrangement from the protective plate to the extruder may be 20 mesh / 40 mesh / 60 mesh, because this arrangement can prevent the filter from being blocked and can "blown" the impurities into the protective plate. Inside the opening.

 

If the finest screen is 80 or more mesh, a rough filter can be placed in front to prevent the filter from being rotated by the molten material or blocked by large impurities (eg 20/100/60/ 20 mesh arrangement). Since this type of device is identical from both sides, in order to ensure that they are not reversed, a symmetrical arrangement (20 mesh / 60 mesh / 100 mesh / 60 mesh / 20 mesh) is sometimes used.

 

Some processors deliberately reverse the filter and allow the coarse filter to filter larger particles on the upstream surface. They believe that this method allows more of the side molten material to pass through and decomposes less material on the upstream surface of the protective sheet.
