Underwater Pelletizers
The BKG Type AH D pelletizers are designed for large throughput operations and deliver cutting-edge automation. These pelletizers offer precise and consistent blade pressure regulation, ensuring high-quality pellets even for complex and demanding materials in an underwater pelletizing system.
Overview
The BKG Type AH D underwater-pelletizer is equipped with hydraulic blade pressure regulation and a hydraulic locking mechanism, making it our most advanced and automated model. As part of an underwater pelletizing system, it can handle high throughputs, complex materials, and challenging processes with ease.
A blade wear indicator and the ability to automatically re-sharpen blades during operation ensure optimal cutting performance while minimizing downtime and operator intervention.
One Concept – Different Processes
The BKG Type AH D underwater-pelletizer is compatible with a wide range of die plates and cutter hubs, allowing you to produce pellets that meet your exact requirements.

Bypass
The BKG Bypass Piping system surrounds the cutting chamber, allowing precise timing of process water entry. This system includes:
- (2) 2/2-way valves
- (1) 3/2-way valve
- Related PLC programming for optimal control.
Benefits
- Prevents freeze-off (blocking) of the die plate holes caused by premature water entry into the cutting chamber
- Avoids pellet agglomeration caused by delayed water entry
- Reduces volumetric loss of process water during pelletizer stoppage or uncoupling
