Double-piston continuous screen changer realizes a non-stopping screen changing operation by altering two pistons with double filtering areas. During production, the polymer melt is divided into two flow channels inside the screen changer housing, then conveyed through the two filters equipped with the appropriate filter medium. This filter medium consists of screen packs supported by breaker plates.
It can match with extruders of different design. It is applicable to process with most polymers at high output.
Double-channel nonstop screen changer work alternatively, which can change the screen with minimum melt pressure fluctuating and production interrupting.
Two stages air vent for the hydraulic system to eliminate bubbling in polymer flow.
Superior sealing system completely eliminates polymer leakage.
External safety cover gives better appearance and safe protection.
It is equipped with circular、elongated or U- shaped screens, for enlarged filtration area.
Eliminates line shutdown thus increasing production
Two breaker plates design increases filtration area compared to single breaker plate design
Reduced downtime & scrap
Reduced inlet pressure at extrusion die
Reduced temperature variations in the melt
