Manual Screen Changer

The manual screen changer comprises a main body, two screens and other components, forming an integrated filtering system. Screen changing is achieved by manually pulling the operating handle to switch between the screens.

Advantages of the Manual Screen Changer:
1. Cost-Effective: Features a simple structure with low manufacturing costs.
2. Easy to Operate: No complex control systems required. Operators can master screen-changing operations after brief training.
3. Low Maintenance: Simple design results in a low failure rate, enabling easy maintenance and repairs.
4. High Durability: Constructed from alloy materials with nitriding treatment, offering robust structure, high-temperature resistance, corrosion resistance, and suitability for long-term high-load operation.
5. High Pressure   Resistance: Capable of withstanding a maximum working pressure of 50 MPa.

Disadvantages of Manual Screen Changers:
1. Requires Shutdown for Screen Changes: Production must halt during screen changes.
2. Manual Operation: Screen change relies on manual intervention.
3. Limited Filtration Area: Only suitable for production lines with low capacity and infrequent screen changes.
 

The manual screen changer features a simple structure, high reliability, and stable performance during long-term operation, with low susceptibility to failures. It is particularly suitable for small and medium-sized enterprises engaged in multi-variety, small-batch production. Its main applications include small-scale film blowing lines, granulation production lines, and testing machines.​
