BKG® Combigon™
BKG Combigon™ systems come equipped with Polygon™ automatic filter and are available with optional belt filter. The process water exits from the dryer and enters the filter unit which is comprised of several screen elements. The water level in the filter unit is monitored. If the level rises, the filter unit is rotated by means of a gear motor so that clean screen elements are always in the filtering area. The dirty screens are cleaned by means of water jet cleaning nozzles. The contaminant is sprayed onto a declined water slide and deposited into a filter cassette drawer which must be cleaned periodically. As an option, a continuously operating belt filter is available in place of the filter cassette drawer.
Benefits:
Continuous, automatic water filtration
High level of automation, reduced operator intervention
Improved water filtration level (up to 70μm)
Optional belt filter maximizes system automation
Energy savings during operation through elimination of secondary pump
Features:
Polygon™ automatic filter + secondary filtration
Self-cleaning tempered water system
Modular design
Completely skid-mounted
Dual door dryer access for easy cleaning
Based on the Combi-Line™ system but with enhanced water filtration
BKG CrystallCut® underwater pelletizing system is designed for PET polymer production and recycling and allows for the pelletizing and crystalliization of PET in ONE single process step without the need for additional energy.
Benefits:
Viscosities between IV 0.4 und 0.9 dL/g (PET)
Crystallization up to 40% and above without additional use of energy (virgin PET)
Complete, continuous process
Verifiable reduction in production cost
Lower energy consumption compared to conventional crystallization
Direct conveyance into SSP is possible
The product is almost dust free
No sticking together of the PET pellets
Increased bulk density of PET pellets by up to 8%
Quick and easy start-up and change of product
Features:
Crystallization by use of the energy present within the pellets
The BKG Lab-Line™ underwater pelletizer system is the ideal machine for pilot-scale extrusion or laboratory environments. The BKG Lab-Line™, which features simple controls and a compact design, is made up of a BKG pelletizer (hanging design), a BKG pellet dryer and a BKG process water treatment system.
The complete system is mounted on a single, rollable cart for mobility and easy handling in a lab environment where equipment is frequently exchanged.
Benefits:
Mobile design, compact footprint
Flexibility for material and / or color change
Easy and fast cleaning of the system components
Easy operation, simple handling
Ideal for pilot scale lines or laboratory environments
Features:
Simple controls
Compact design; complete system mounted on one single, rollable cart
Able to process nearly all types of polymer products processed on production lines
Pelletizer with manual fine adjustment of the blade pressure
The BKG agglomerate catcher prevents pellet clusters or clumps (agglomerates) from entering the rotor area of the dryer. Agglomerates are captured by a series of inclined metal bars and automatically detected as they break the light beam of a photo-electric sensor. When the photo-eye detects an agglomerate, the agglomerate gate automatically opens and the oversized material is ejected upstream of the pellet dryer.
The BKG Master-Line™ with Belt Filter water filtration system is an enhancement of our widely-popular Master-Line™ Underwater Pelletizing System. The Master-Line™ with Belt Filter offers the addition of a continuous belt filtration system for our BKG Master-Line™ 1000 & 2000 models. It is an economic, automated, self-cleaning tempered water system which minimizes operator intervention and maximizes productivity and uptime.
The BKG Master-Line™ with belt filter is suitable for compounding, masterbatch, and recycling applications as well as for brittle materials which can generate a high degree of fines.
Benefits:
High level of automation, reduced operator intervention
Master-Line™ can be upgraded to the automatic Belt Filter
Fine filtration at 150μm
Compact footprint
Automatic water filtration at an economical price
Features:
Continuously rotating filter belt
Self-cleaning of the filter belt with scraper and spray nozzles
The BKG Optigon™ is our state-of-the-art underwater pelletizing system offering the optimum level of features, and, in comparison to the BKG Opti-Line™ system, is delivered with the Polygon™ drum filter for automatic, continuous filtration of the process water.

Nordson has been dispensing thermoplastic materials since 1964. Plastics manufacturers worldwide rely on Nordson technologies to melt, homogenize, filter, meter, and give shape to plastic and fluid coating materials.
Through a series of recent acquisitions, Nordson has brought together the best in plastics applications.
Our polymer processing team leverages more than 200 years of collective corporate experience in the plastics industry to produce a full range of precision melt stream products — from screws and barrels to filtration systems, pumps, and valves for extrusion and injection molding — to the dies used to create film, sheet, coatings and pelletizing systems to meet the constantly evolving needs of the polymer industry.
Nordson uniquely understands all of the components in the melt stream. We draw on this knowledge to help customers by recommending ways to optimize their overall melt stream process, increase productivity, reduce costs, and enhance product quality.
With sales organizations in 30 countries, Nordson supports our customers long after a sale is complete, whether its by providing ongoing technical services or recommending the best products to optimize the melt stream process and reduce costs.
Nordson believes that innovation is critical to supporting our customers changing technology needs, so that they can drive results for THEIR customers. We continue to invest millions of dollars per year in research and development to offer the best solutions for the high-end processes, equipment and applications that produce plastics.
