Continuous Screen Changer

Continuous Screen Changer (CSC) Features Include:
- Guaranteed leak-free operation to 10,000 psi
- Breaker plate open area largest in the industry
- All parts manufactured to ISO-9002 standards
- No seals or contact parts
- Rugged design provides resilience to wear
- Minimum pressure drop
- Continuous operation means no shut down
- Process temperatures to 650° F
The Continuous Screen Changer allows for filtration of most all polymers without interrupting production during a screen change. The Continuous Screen Changer consists of two screen bolts with each containing a filter cavity. When a screen change is required, one of the bolts is moved out of the housing while the other remains in the operating position. The dirty screen pack is removed and replaced with a new one. The bolt is then moved back into the housing to its venting stages before resuming operation. These steps are then repeated for the other bolt. This concept allows for continuous filtration with no interruption or loss of production. PSI Continuous Screen Changers can be designed to withstand extremely high pressure applications. PSI guarantees leak-free operation up to 10,000 psi.
Benefits:
- Design allows for a screen change without interrupting material flow

[@mullmiller]

what do you do when a piston bypasses the degassing/venting stage and goes straight in without stopping?

[@EsotericHunter]

You would lose sheet then. But you only change one screen at a time, which is enough to maintain PSI. They are programmed to slowly reenter allowing enough pressure to build as to not lose too much PSI.

[@mullmiller]

@@EsotericHunter loose sheet?

[@EsotericHunter]

@@mullmiller Sorry. We run extruders that run through a die producing a sheet. Basically if the piston returns too fast you will lose PSI. Which may not be a problem with certain processes, but a major process with others.

[@mullmiller]

@@EsotericHunter yea we didn’t run die. And yea we did lose psi. Which is why i was asking
