Extruder Screen| Melt filter
The extruder screen is placed next to screw and breaker plate play a role to support the screen. The main idea of using metal wire mesh extruder screen is to prevent impurities from obstructing or passing through the die.
Also, extruder screen creates an additional resistance to continuously flow of material, which helps to raise the level of viscous working and mixing due to increase the head pressure. Also plays a role for adapter valve between screw and dia.
The screen sandwich is a collection of different metal meshes, the finest mesh is the main filter media for incoming melt and supported by successively coarser thicker metal mesh.
STAINLESS STEEL SCREEN FOR EXTRUDER
Stainless steel screen for extruder is woven type with stainless steel wire mesh cloth. There are different possible woven patterns to weave the metal mesh like: plain weave, twill weave, Dutch weave, twill Dutch weave and reverse ditch weave. The stainless-steel extruder screen design in multiple combination, like single layer, double layer, multiple layers etc.
The main industries for these extruder mesh are: plastic & polymer processing industry, chemical industry, rubber industry, pharmaceutical industry and many more.
MULTIPLE LAYER EXTRUDER SCREEN MESH:
The combination of different metal mesh sizes or micron sizes is known as multiple layers’ extruder screen or sandwich mesh screen. This kind of screen used in high precision filtration & separation industry.
The mesh layers are joint together with spot welding. Also, extruder screen border or without border used as per machine requirement. In close border, the edges are compressed along with solid strip known as RIM.
There are different shapes:
- Kidney-shaped extruder screen.
- Copper and brass extruder screen
- Cylindrical extruder screen.
- Pleated or sintered extruder screen.
- Extruder screen filter discs.
- Multilayer extruder screen packs.
- Circular extruder screen.
- Ring-shaped extruder screen.
- Stainless steel extruder screen.
- Filter belts for continuous screen changers.
