Plastic granulator screen changer features

Introduction of double-column four-station screen changer

Double-column four-station screen changer is used for the filtration of thermoplastic materials such as plates, sheets, films, fibers, strapping, granulation and other processes that require stable pressure; it can be designed for polymerization lines, co-mingling and other processes.

Double-column four-station screen changer working principle

Plastic pelletizing double column four-station screen changer is designed as double column four-station, four nets work at the same time, change the net without interrupting the material flow, without interrupting the product. Designed with charging and exhausting system, it can fully eliminate the gas trapped in the material and the porous plate to be changed to ensure the quality of the products. The four-flow design improves the filtering area and meets the requirements of higher quality and production. This product is suitable for high capacity, high efficiency, large-scale extrusion equipment for continuous operation, is a better choice for product manufacturers.

Features of double-column four-station screen changer

1、Four flow channels and four stations, four nets work at the same time, relatively small cavity, providing a larger filtration area;

2、Rigid sealing structure, no leakage;

3、Reasonable priming and exhausting structure to ensure continuous and stable products;

4、There are three filter meshes working when changing mesh/ priming and exhausting, and the pressure fluctuation in the process of changing mesh is small;

5, PLC control can be realized, the operation of automated control, reducing the cost of manual intervention of the operator;

6、It can realize automatic alarm and control to ensure the safe and stable operation of the system;

7, for polymerization line, co-mingling and other processes can do targeted structural design.

Double-column four-station 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 media heating.
