Nordson BKG

The BKG® FlexDisc™ allows for a significantly enlarged filtration area, without increasing the machine size and weight. You can realize sizes of filtration areas that are far beyond what flat screens can provide.

Applications:

• Bottle-2-Bottle Recycling
• PET Fiber Production
• Battery Separator Film

Benefits*:
Compared to conventional single round screens

• Larger filtration area
• Finer filtration
• Higher throughput
• Prolonged filter life of filtration media
• Reduced specific backflush volume due to fewer required backflushes
• Gentle filtration - less shear stress and therefore protection of the molecular structure and increase of the end product quality (less gels)
• Smaller machine size for same throughput possible

Features:

• Robust design
• Rheologically optimized
• Mechanically reinforced
• Backflushable
• Reusable
• Retrofittable
• High quality filtration media

The BKG HiCon V-Type 3G is suitable for almost all processes and materials. It is used in processes with a high demand for pressure consistency (e.g. strap, film, fiber) as well as in processes with insufficient back pressure for backflushing (e.g. strand pelletizing). It is also suited for processes with a high proportion of contaminates (e.g. recycling). The system enables a continuous operation without any system shutdowns during screen change.

Benefits:

• All process steps are performed pressure- and volume-constant
• Patented POWER BACKFLUSH technology ensures highest efficiency and operates independently of the extrusion pressure
• Fully automated backflushing and venting procedure reduces operator intervention to a minimum
• Up to 200 backflushing cycles allow for a significant reduction in operating cost 
• Four screen cavities provide a large filtration area in a comparably small housing, with only minimal backflushing amounts during the self-cleaning

Features:

• Patented highly efficient backflushing through integrated POWER BACKFLUSH technology
• With the patented 4K-75-technology, three screen cavities (75%) remain available for filtration at all times during the process steps “backflush” and “screen change”
• Optimized flow channel geometries (free of dead zones)
• Wear-free metallic sealing system – no additional seal required
• Easily integrated into the line controls

 
New generation efficiency enhancement: Old vs New 

• Increased cleaning performance through reduction of the backflushing cycle - only one displacing piston
• Higher degree of automation through autonomous parameterizing of venting and backflushing
• Easy and clean handling through an outlet for the backflushing discharge on the bottom of the housing 
• Lower extrusion height possible through compact construction
• 100% of the filtration area available during reservoir filling procedure

For an efficient filtration process and to exploit the full potential of the filtration system a state-of-the art filtration medium is essential. The Nordson Screen Pack is designed with all our knowledge of polymer processing and is the strong core your filtration system needs.

The Nordson Screen Pack is made of high-quality weaves, combined to ensure the highest filtration efficiency. Square weave layers provide unique structural strength and ensure maximum stability against mechanical stress. Layers from an optimized Dutch weave ensures maximum permeability. Nordson Screen Packs are tailored to the cavity and provide optimum peripherical sealing. The screen pack and all its layers are cleaned ultrasonically to protect your process from any kind of contamination.

Benefits:

• Efficient filtration of contaminations, e.g. fiber, wood, paper, black specks, gels
• Prolonged working life of the screen pack, more output between screen changes
• Increased product quality
• Easy installation

Features:

• High-quality weaves, combined to meet your process requirements
• Tailored to the cavity
• Spot welded for maximum stability
• Ultrasonically cleaned
• Available in various sizes
