Product category: Screen changers

Double-piston Continuous Screen Changer with Double Working

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, and then conveyed through the two filters equipped with the appropriate filter medium. This filter medium consists of screen packs supported by breaker plates.


It matches with extruders of different design. It is applicable to process 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, thus eliminate the defects on final products.

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.

Continuous Screen Changer with Four Plate Circulation

This series of screen changer consists of four independent breaker plates, each with openings of same diameter and screen pattern. The rotation of these specially treated alloy metal plates gives superior sealing ability and durability. This type of screen changer has slight flow fluctuation during screen changing. It can guarantee a continuous and stable extrusion production.


Breaker plates move in the same direction one by one, improved filtration performance, convenient to clean.

Equipped with preheating and ventilation design to minimize the effect of possible temperature, pressure, melt flow fluctuation on final product during screen changing process.

Guaranteed NO rupture on film and filament production, and changing the screen without stopping the production.

Double-plate Hydraulic Screen Changer with Double Working Po

Double-plate hydraulic screen changer realizes a screen changing operation by altering two plates with double filtering areas while keeps the continuous extrusion production.


Suitable for the extrusion processing of most polymer materials.

Continuous production and filtration process during screen changing, no obvious fluctuation on extrusion and greatly improve production stability and quality.

Works well at high pressure of 25-30 MPa.

Unique sealing design improves seal ability and durability.

Double Piston Screen Changer with Backflush System

Double-piston large area screen changer I our patent pending (international and Chinese)developed in 2009. It is specially designed for recycling compounding and large throughput extrusion process.


Due to the very effective screen cleaning with high pressure impulses, the efficiency of the screen-cleaning exceeds 80% , repeated usage up to 400 times (depending on the filtration fineness), minimizing the screen operational cost. Eliminate busy operation in the process of filter calcinations, ultrasonic cleaning, chemical immersion, and save the cost of various cleaning equipment.

100% availability of the production line while cleaning and replaced the screen, elimination of scraps. Low operation costs of production.

Automatic Belt Mesh Screen Changer

This new model is designed to extend the application of Belt Screen Changer into much larger polymer ranges. The conventional model has lot of advantage in the polymer filtration operation but due to its special mechanism of screen changing motions, only limited number extrusion productions of polymers with suitable viscosity and stability can adopt. This new model will eliminate these limitations on polymer materials and pressure ranges, greatly extended the range of extrusion productions to take advantages the unique stable polymer flow.
