How to work
The screen moves across the flow of plastic melt and a fresh screen enters as the spent filter screen exits; removing the impurities from the raw material. The belt screen changer is fitted between the end flange of the extruder and the die. A cassette holding a roll of screen filter is attached to the side of the belt screen changer block. The controlling box of belt screen changer is equipped with a pressure sensor, and a pressure warning device, when the pressure is raise to the preset , it will automatically alarm, at the same time, the screen is replaced automatically. And the cooling system begin to work , the impurity is cooled and moved out with the filter screen.
Widely used for:
1. Extruders (Plastic Extruder, Cast Film, Blown Film Extruder, etc)
2. Plastic pipe production line
3. Pipe, PA, PET and PVC sheet extrusion lines
4. Pelletizer,Granulation, Non-woven, Plastic recycling and Monofilament machine
Our advantages
We are specialized in the research and manufacturing of
melt filtration device/screen changer for more than 20 years. With strong scientific research team and mature technology; hold many international and national invention patents.
Our items can not only filter impurities, but also can greatly improve the plasticizing and homogenization effect of the raw material, make the product structure more homogeneous and product surface smoothness and quality much better, energy-saving and consumption-reducing, output- increasing and labor-saving
