Rigid PVC/Polypropylene Extrusion Pelletizing Screen Changer

Pelletizing screen changer is used for chemical fiber, blown film, flat film, cast film production, pipe, sheet, wire, fiber manufacturing, pelletizing line, recycling, etc. It can meet the production of high temperature, high pressure and high extrusion of any polymer material. It can be used in conjunction with extruders of different standards. It does not stop to change the screen, the product is not interrupted, and the material is not leaked. Hydraulic pelletizing screen changer is used for chemical fiber, blown film, flat film, cast film production, pipe, sheet, wire, fiber manufacturing, pelletizing line, recycling, etc. It can meet the production of high temperature, high pressure and high extrusion of any polymer material. It can be used in conjunction with extruders of different standards. It does not stop to change the screen, the product is not interrupted, and the material is not leaked.

Rigid PVC granulation screen changer adopts dual-channel dual-station design. When working, two filter stations work at the same time. When changing the screen, the two filter stations exchange and replace the screen. Unblocked, in order to achieve the effect of continuous stripping in the production of underwater strip granulation, it is suitable for the production of underwater strip granulation. The pp extrusion screen changer mainly removes impurities in the melt through the laser-drilled filter screen plate during operation. Filtration is carried out, and the generated impurities are scraped by the oil cylinder to push the scraper to scrape the impurities on the filter screen to the bottom cavity connecting the main body of the flow channel, and then start the slag discharge system to discharge the waste and impurities to complete the filtration and slag discharge. No material leakage, continuous stripping and continuous production are not affected, and are now mainly used in recycling granulation production.

Features of plastic pelletizing screen changer:

1. The granulating screen changer is designed as a double-channel and double-filter structure. When changing the screen, one screen works and one screen is replaced, without interrupting the material flow and product, and realizing the screen change without stopping.
2. An exhaust system is designed, which can fully remove the gas contained in the material and the porous plate to be replaced, prevent the gas from forming in the product during the screen changing process, and improve the quality of the product.
3. The double-flow channel design increases the filter area and meets the production requirements of higher output and higher quality.
4. Large filter area, suitable for extrusion production of different materials and products.
5. It has good sealing characteristics, rigid sealing and long service life.
6. It has the functions of charging, exhausting and discharging to ensure the continuity of products during the screen changing process.
7. Various sizes and specifications can be specially designed and processed according to user needs.
8. The structure design is reasonable, the operation is convenient, and the effect is excellent.
9. The filter screen on the cylinder of the same size can be processed into circular, cambered, oval, cylindrical, etc.
10. It has a safety shield design.
