Mesh Belt Type Continuous Screen Changer

The mesh belt type continuous screen changer  comprises a main body, a heating/cooling system, and an electronic control system, forming a complete filtering system. As filtered impurities accumulate on the screen, the operating pressure of the screen changer rises continuously. When it reaches the set value, the pressure sensor triggers a screen - change signal. Then the electronic control system is activated to enable automatic mesh belt movement.​
Each roll of mesh belt can be customized in terms of width and length according to customer requirements. Its maximum service life can reach up to 6 months.

Advantages of Mesh Belt Type Continuous Screen Changer:​
 
1. Extra-long service cycle: The mesh belt length can be customized, a single roll can last up to 6 months of usage.​
2. Closed operating environment: No air enters the flow channel during screen changes. The melt flow remains uninterrupted, with minimal pressure fluctuation, ensuring continuous production is not affected.​
3. High automation level: The screen-changing process is fully automated, requiring no manual intervention.​
4. Smooth screen-changing process: Both output and product quality remain consistently stable.​
5. Optimized design: The front end of the equipment is equipped with an electric roller device, which flattens the mesh belt to facilitate its entry into the main body—solving the problem of difficult mesh belt replacement.​
6. Energy-efficient and environmentally friendly: No waste is generated during screen changes, and long-term continuous operation reduces energy consumption.​
7. Good economy: Lower expenditure on consumables.​

Disadvantages of Mesh Belt Type Continuous Scre en Changer:​
1. Limited applicable working pressure: It generally does not exceed 20Mpa.​
2. Narrow application scope: It is mainly suitable for scenarios such as wire drawing and cast film—where continuous production, small pressure fluctuation, and continuous flow are required.​

The unique design of the mesh belt type continuous screen changer allows for long-term continuous operation. Its main application scenarios are as follows:​

◆ High-quality or long-process products, such as composite films, cast films, sheets, plates, optical fibers and various fibers; It is suitable for materials like PC, PMMA, PET, PS, PU, PP, PE, EVA and ABS.​
◆ High-precision products that require low pressure fluctuation.​
◆ Polymers granulation, such as PP, PE, ABS and PS.
