G250 MFC Grinder Process Integration
Integrated MFC production at industrial scale.
The G250 is designed for full-scale integration into large paper and board mill operations, where MFC production becomes a continuous part of the manufacturing process.
As with all models in FiberLean’s MFC grinder range, the G250 can be installed as a standalone unit or as part of a satellite MFC system, integrated into wet-end systems, allowing mills to introduce MFC production without impacting core operations.
This allows MFC production to operate as a stable, high-capacity process within the overall mill system.

FAQs
What production capacity can the G250 MFC grinder achieve?
The G250 MFC Grinder typically delivers around 1,200 dry tonnes of MFC per year per unit (140 kg MFC/hour), with higher outputs achievable through modular installations.
Is the G250 designed for continuous industrial operation?
Yes. The system is engineered for 24/7 operation within large-scale paper and board mill environments.
Can the G250 supply multiple production lines?
Yes. The system can be configured to supply MFC to multiple machines or high-volume single-line operations.
How is the G250 integrated into large mill infrastructure?
The G250 can be installed as a standalone unit or as part of a satellite MFC system, allowing mills to produce microfibrillated cellulose in-house without impacting core operations.
What is the typical installation footprint and infrastructure requirement?
The G250 requires a larger installation footprint than smaller models (2.6m x 2.6m) and a storage tank, but is designed for integration within existing industrial layouts with defined interfaces.
Can multiple G250 units be installed together?
Yes. Systems can be deployed modularly to meet higher production requirements.
