Screen Changer for discontinuous operation Type HS-Y |
| |
Hydraulically actuated Screen Changer for discontinuous operation |
| |
The range of compact HS-Y Screen Changers are built to KREYENBORG's exacting quality standards and are the economic solution to filter polymers. HS-Y discontinuous melt filters are used where screen changes are rarely needed, and it is no problem to stop the production when changing screens.
Applications
- quality filtration of virgin polymers
- protection of downstream equipment such as KREYENBORG gear pumps
- film extrusion with virgin polymer, co-extrusion etc.
Materials
- suitable for all polyolefines as well as many technical polymers
Customized special solutions
- possibility to extract the extruder screw through the screen changer
- high pressure design (up to 800 bar)
- special die plates
- inexpensive integration of adaptors into and onto the round housing
Function
- discontinuous melt filter
- the extruder has to be stopped momentarily (approx. 4 min.) for the screen change
- very simple handling for the operator
- piston is moved out of the housing hydraulically (the screen bearing piston remaining in the housing, blocks the flow channel). Once the new filter medium is inserted, the screen bearing piston is moved back into the operating position
