hydraulic screen changer for recycled plastic granule

The plastic granulator screen changer is mainly used in granulation, PE, PP, PPR, PERT pipes, plates, sheets, casting films, non-woven fabrics, chemical fiber spinning, and other production processes that require uninterrupted material flow and high continuity during screen changing.

Working principle of plastic pelletizing screen changer

When the granulator screen changer is working, two filter screens work simultaneously. When the screen needs to be changed, the hydraulic station can be activated to perform the screen change action. When replacing the filter screen, one screen works, the other screen is replaced, and the two screens alternate. Through the material introduction and exhaust devices, the air in the flow channel is completely discharged to achieve the production requirements of no shutdown screen change, no material leakage, no interruption of material flow, small fluctuation of material pressure, small impact on production, and good continuity.

Characteristics of hydraulic screen changer for plastic granulation

1. Designed with an exhaust system, it can fully eliminate gas inclusions in materials and the porous plate to be replaced, prevent gas formation in the product during the mesh changing process, and improve the quality of the product;

2. The dual channel design increases the filtration area, meeting the production requirements of higher yield and higher quality;

3. Large filtration area, suitable for extrusion production of different materials and products;

4. Has good sealing characteristics, rigid sealing, and long service life;

5. Equipped with the functions of filling, exhausting, and discharging pollutants, it can ensure the continuous production of the mesh changing process;

6. Zhengzhou Batte non-stop screen changer can be specially designed and processed in various sizes and specifications according to user needs;

7. Reasonable structural design, easy operation, and excellent effect;

8. The filter screen on the same size column can be processed into circular, curved, elliptical, cylindrical, etc.

Configuration plan for granulator screen changer

1. The main body of the screen changer (oil cylinder, heater), standard hydraulic station (oil pipe 2 meters) (standard configuration of the Bart screen changer);

2. The main body of the screen changer (oil cylinder, heater), standard hydraulic and electric control combination system (pressure sensing, pressure alarm, independent temperature control system);

3. Main body of screen changer (oil cylinder, heater);

4. Body cover (optional).
