BOA Compactor
The BOA Compactor combines advanced conditioning with high efficiency pre compaction as an alternative to double pelleting or expanding. Steam and liquids are added in a double walled mixer before compression in a hydraulically controlled compacting chamber. Adjustable paddles and a three roller head ensure uniform mixing, better steam absorption, higher pellet quality, increased capacity, and lower energy use with simple integration into existing automation.
- High-quality pre-compaction for improved pellet strength
- Optimized steam and liquid absorption
- Higher pelleting capacity with reduced energy use
Efficient pre-compacting for higher pellet quality
The BOA compactor combines intensive mixing with controlled pre-compaction to improve pellet quality and increase capacity. Accurate hydraulic control of the compaction level ensures consistent results, while the integrated mixing chamber provides uniform distribution and effective absorption of steam and liquids. This results in flexible raw material use, lower energy consumption compared to double pelleting or expanding, and a hygienic, low-wear process.
