Self-cleaning back flush screen changer for extruder
This kind of screen changer has owned the international patent( Europe and America), and owned our national patent, China patent.
The features of this kind of self-cleaning back flush screen changer
1, large screen area, for 365cm2 to 11000cm2, meet the requirement of high yield extrusion line. such as the plastic recycling granulator and compounding.
2, self-cleaning system, no need to change the screen, but wash the screen on line. the dirty screen is washed by the cleaning material .
3, one screen can be used for more than 100 times, this make the cost of the screen comsumption lower.
4, Less labor interference.
This kind of self-cleaning back flush screen changer can be used for
1, almost all kinds of polymer materials , especial for the recycling granulation with lots of impurities , such as PE/PP/PS/ABS/PET/PA/etc.
2. the production line of chemical fiber, rubber, collosol, adhesive, coating and finishing materials and other blending agent products, used for filtration of the material mixture.
3. It has been applied in the United States PS recycling machine. Its output is 1100kg/hr, filtration precision of 40-60 mesh, new screen pressure of 2.5Mpa, material pressure of 7.5Mpa after admixture. The material pressure reduced to 2.5 -2.7Mpa after strongly washing the filter, filter cleaning rate exceeds 90%.
