Product Description
Hydraulic screen changer-double piston type
This hydraulic screen changer-double piston type is designed to work with two channels inside. It contains two screens that work at the same time: one screen works, while the other one is changed during the process of screen replacements, thus the replacement without machine halt is ensured and no interrupt of material fluid and of production will occur. Therefore, the screen changer meets the customers' requirement of higher productivity and better quality.
How to work
The double piston Screen Changer allows for filtration of most all polymers without interrupting production during a screen change. The Screen Changer consists of two pistons with each containing a filter cavity. When a screen change is required, one of the pistons 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 piston is then moved back into the housing to its venting stages before resuming operation. These steps are then repeated for the other piston. This concept allows for continuous filtration with no interruption or loss of production

Benefits of hydraulic screen changer- double piston type
1, Eliminates line shutdown thus increasing production
2, Leakage-free process
3, Two breaker plates design increases filtration area compared to single breaker plate design
4, Reduced downtime & scrap
5, Reduced inlet pressure at extrusion die
6, Reduced temperature variations in the melt ·
