Double column hydraulic non-stop screen changer

Application range of dual plunger screen changer

1. Granulation production;

2. Pipe production (PE PPR PERT) and various types of plastic pipes such as water supply pipes and gas pipes);

3. Production of plates and sheets;

4. Production of cast film;

5. Production of chemical fiber spinning;

6. Various types of chemical fluxes require uninterrupted material flow and high continuity in production when changing nets.

Structural characteristics of continuous screen changer for casting film extrusion

1. Dual plunger, dual flow channel, dual station, dual network working simultaneously;

2. Alternate replacement of dual networks to ensure the normal production process;

3. Adopting a rigid sealing structure, safe and reliable without leakage;

4. Progressive feeding and exhaust structure, with small pressure fluctuations during the mesh changing process, ensuring continuous and stable product production;

5. Optimize the design of the flow channel structure, without dead corners or stagnant flow;

6. The detachable orifice plate structure facilitates material cleaning;

7. It can achieve automatic alarm and control, ensuring the safe and stable operation of the system.
