Piconizer laboratory jet mill
The Piconizer laboratory spiral jet mill processes soft to medium-hard products particularly gently and efficiently. Thanks to its integrated classifier, flexible design and reproducible process control, it produces fine powders with defined properties for demanding laboratory and development tasks. As part of the modular system, it can be easily integrated into the Picoline platform.
Your benefits at a glance
- Spiral jet mill for dry grinding of soft to medium-hard materials
- Archiving of process data in the platform
- Compressed air or inert gas operation
- Lid with integrated static classifier and integrated nozzle ring with four nozzles and grinding air connection
- Nozzle ring with dead space-free milled nozzles
- Mill housing with integrated injector for material feed
- Tubeless grinding and injector air supply through platform adapter
- Designs: Stainless steel and wear-protected (ceramic) variant
- Also available as a stand-alone version without platform: Electroless version purely via compressed air, control via manual valve, small space requirement
- The design and mode of operation largely correspond to the AS series from Hosokawa Alpine

- Several gas nozzles are used to generate a rapidly rotating vortex of air. The ground material is fed into the disc-shaped grinding chamber via an injector.
- The comminution takes place through particle collisions caused by the velocity gradients in the air flow.
- The grinding gas is discharged through an immersion tube located in the centre of the grinding chamber. The potential vortex flow creates a classifying effect so that only fine particles can leave the grinder through the immersion tube and are separated in a cyclone filter combination, cyclone or filter. Coarser particles remain in the grinding chamber until they have reached the desired fineness.
- The grinding gas quantity, the grinding gas pressure and the throughput can be varied to set the degree of micronisation.
