The dual flat-plate hydraulic screen changer is based on the slide-plate screen changer. It provides screen changing without stopping production by alternating between two plates

Dual flat-plate hydraulic screen changers are used in compounding, masterbatch, recycling, sheet extrusion, profile extrusion, pipe production, pipe coating, and biaxial orientation.

1. Hydraulic cyclinder moves one plate out of the housing
2. Polymer melt flow passes through the other filter screen during changes
3. Old screen is replaced with clean one and the plate is returned to the production position
4. Polymer melt flows back through the two screen again until another screen change is necessary

• 500 kg/hr - 2,000 kg/hr
• Works well at high pressures of 25MPa - 30MPa
• Polymer melt separated between two plates (one screen in each plate) on the inlet side
• Provides continuous production
• Twice the filtering area makes it suitable for high output extrusion lines
• Uses a a precise electrical ruler controller system
• Hydraulic system provides secure operation

• Screen changing is less than 2 seconds
• No air bubbles in product
• Higher output rate than slide-plate screen changer because twice the filtering area
• Compact design shortens the heating period and reduces heat loss
• Good for thermally sensitive materials
• Unique sealing systems ensures operation without leaks
