GlobeCore FAQ
I’m researching a process that may require a colloid mill. I’m working with cellulose and want to produce nanocellulose. What type of mill/technology would be most suitable for this, and what key specs should I look at (shear level, gap control, passes, cooling)?

For nanocellulose work, I’d recommend using the GlobeCore AVS vortex layer device instead of a colloid mill. AVS delivers extremely intense particle activation/dispersion in an electromagnetic “vortex layer” (so there is no rotor-stator gap to tune), which is useful for accelerating fibrillation and deagglomeration steps in cellulose slurries. GlobeCore positions AVS for fine grinding, dispersion, and activation. What to spec and control in an AVS-based setup: focus on energy input per liter (kWh/m³), residence time / number of passes (recirculation loop is ideal), and cooling (jacketed feed tank + heat exchanger in the loop) because mechanical nanocellulose routes are heat- and energy-intensive. Reviews of nanocellulose production consistently emphasize mechanical high-shear processing and the importance of repeated passes and process control.
