Extruder continuous screen changer applications, features, configurations and parameters

Extruder continuous screen changer is suitable for applications in pelletizing, PE, PP, PPR, PERT pipes, plates, sheets, cast film, nonwoven fabrics, chemical fiber spinning, etc., which require uninterrupted flow of material during screen change and high continuity.

Extruder continuous screen changer features:

1、It adopts rigid sealing structure to ensure no material seepage under high pressure and high temperature.

2、It adopts one-piece structure without bearing gap, which strengthens the bearing pressure and makes the system with higher bearing pressure.

3、The plunger is made of high quality alloy steel by nitriding treatment, which prolongs the product life cycle.

4、Integrated engineering cylinder, long service life.

5、Alternating working mode can ensure the continuous and stable material flow and the repeatability of process parameters in the process of changing nets.

6、Progressive priming and exhaust structure, small pressure fluctuation in the process of screen changing, continuous and stable products.

Extruder continuous screen changer can be divided into: duplex and quadruplex according to the filtering station; according to the shape of filtering screen plate can be divided into: double plunger round hydraulic screen changer, double plunger curved hydraulic screen changer, double plunger cylindrical hydraulic screen changer.

Extruder continuous screen changer technical parameters:

1、Working temperature: ≤350℃;

2、Working pressure: ≤50MPa;

3、Differential pressure: ≤20MPa;

4、Applicable melt viscosity: 100~30000Pa.s;

5、Heating method: electric heating/thermal medium heating.

For the extruder continuous screen changer provides two configurations, standard configuration and customized configuration.

The standard configuration is: screen changer body + accumulator hydraulic pump station + heating device;

Customized configuration: screen changer body + accumulator hydraulic pump station + heating device + PLC control cabinet.

BATTE melt pumps have nearly two decades of experience in the development and production of screen changer, for plastics, rubber, chemical fiber, adhesives, melt glue, finishing materials and other types of melt impurity filtration to provide a perfect non-leakage, no downtime screen changer solution.
