BKG® Type AH Underwater Pelletizers
The BKG® Type AH underwater pelletizer for medium throughputs is a real allrounder in pelletizing processes. The compact and robust design and a high level of automation make it an excellent fit for nearly all materials and applications.
Overview
The BKG® Type AH underwater pelletizer with automatic hydraulic blade pressure regulation can handle various throughputs and can be combined with most tempered water systems in our portfolio. It's suitable for many materials and has been proven in countless applications.
A blade wear indicator and the fully automatic re-sharpening during operation ensure a perfect cut and minimize downtimes and operator intervention.
One concept - Different processes
To produce precisely the pellet you envision, the BKG® Type AH pelletizer can be equipped with a great diversity of die plates and cutter hubs.

Benefitting Your Process
Increase Profitability
- Increase extruder uptime with maximum process continuity
- Save operating costs through simple handling and easy maintenance
- Be flexible by using different die plate/cutter hub combinations to suit your process
Increase Quality
- Produce precisely the pellet you want by combining it with a large variety of die plates and cutter hubs
- Produce perfectly cut pellets even under changing process conditions through immediate AND precise pressure adjustment for the perfect cut
- Ensure consistent pellet quality independent of operator experience through the easy-to-use control system
Increase Convenience
- Reduced wear due to optimized and constant pressure settings
- Reduce downtime and operator intervention through automatic blade regrinding during operation
- No disassembly and external refurbishment are necessary thanks to possible in-line grinding of the die plates
- Easy and quick start-up process to get your line up and running fast
How it works
General working principle of a BKG® Underwater Pelletizer
Bypass
The BKG® Bypass Piping indicates the piping surrounding the cutting chamber. Entry of process water into the cutting chamber can be precisely timed via the bypass piping system, including (2) 2/2-way and (1) 3/2-way valves and related PLC programming.
Benefits
- Prevents freeze-off (blocking) of the die plate holes caused by the process water entering the cutting chamber too early
- Prevents agglomeration of the pellets caused by the process water entering the cutting chamber too late
- Mitigates a high volumetric loss of process water when stopping/uncoupling the pelletizer
