How is backflush screen changer working

Backflush screen changer working with a PLC control system through the screen changer for recycling process. Powerful back flushing system,greatly improve the product quality,reduce screen pack consumption and cost,improve the production cost efficiency.

Self cleaning flow screen changer actuates the filtration screen moving out of the production position and backflushed by the redirected melt stream, allowing pressure to push contaminants off the dirty screen pack. The contaminated backflush mass leaves the machine by means of heated drain channel which is installed at the screen changer housing. There the small quantity may be removed or collected. And the cleaned screen is moved back to production position until the backflush cycle takes place again.
