BKG® Underwater Pelletizing Systems

for perfectly shaped pellets

Underwater Pelletizers Tempered Water Systems Pellet Dryers CrystallCut® Ancillary Equipment

Our BKG® pelletizing systems are a modern, cost-effective method of processing not only thermoplastics but also all materials that behave like thermoplastics ensuring a perfectly shaped pellet. There is almost no limit to suitable applications ranging from compounding, hotmelt, masterbatch, and polymerization, to recycling and reclaim. We provide engineered solutions that take your specific process to its maximum level of performance.

Advantages of BKG® Underwater Pelletizing Systems

Spherical pellet shape
- Higher bulk density (5 – 10%)
- Less dust during transportation of spherical pellets
- Smaller contact areas of spherical pellets reduces stickiness
Almost all viscosities can be processed with UWP (approx. 3 Pas to 10.000 Pas)
Production of micro pellets
Automated system with constant product quality, independent on operators
Closed system with clean environment
Flexible footprint, less space “in line”

Suitable Polymers for BKG® Underwater Pelletizing Systems

Acrylic resins (e.g. PMMA)
EPS
Hotmelt adhesives (e.g. EVA-based, APAO-based, PA-based)
Natural resins (e.g. chewing gum)
