Continuous Double Piston Backflush Screen Changers Characteristics:
 
1.Automatic continuous self-cleaning screen changer optimal design of the melt flow way - short melt residence time
2.Low pressure build up - to prevent thermal variations of the melt during the continuous screen changer.
3.No dead spots for fast changes of material or colorapprox.
4.Processes with high demands concerning the process constancy
5.Continuous screen changers with backflush system operational reliability and long durability.
6.Backflush continuous screen changers are typically only used where recycled or very dirty materials are processed.
 
Continuous Double Piston Backflush Screen Changers Applications:
 
1.All thermoplastic materials can be processed
2.All kinds of recycling (pelletizing and direct extrusion)
3.For increasing the screen life times in polymerisation and direct extrusion
4.Especially high portion of recycled material and high portion of recycled material (fibres/straps/non-wovens, films, especially PET recycling) for ensuring a high process and volume flow constancy.
