How To Choose Extruder Screen Changer Filter?
The screen changer of the screen changer has a variety of materials such as copper mesh and stainless steel mesh. The fineness of the mesh ranges from 20 mesh to 120 mesh and the number of layers is up to 5 layers.
The viscosity characteristics of the processed materials must be taken into consideration when choosing. Generally, the smaller viscosity materials should use larger filter meshes, and the larger viscosity materials should use smaller filter meshes.
When using multi-layer filters, the fines can be placed in the middle and the two sides are thickened. If there are only two layers, the thicker ones should be placed on the splitter plate so that the finer ones can be supported to prevent the material from breaking through.
