As ALPINE launched the AFG fluidised bed opposed jet mill onto the market in 1981, it succeeded in revolutionising jet milling. Since then, over 1,000 machines have been sold for a wide diversity of applications.
In jet milling, comminution is exclusively the result of interparticle collision in the gas jets. And because there are no machine components in the grinding zone, neither machine wear nor product contamination occurs. This is why jet milling is often used when contamination-free products are required.
Jet milling is suitable for any material hardness value: from Mohs' hardness 1 (talc) to Mohs' hardness 10 (diamonds).
Fluidised bed opposed jet mill for manufacturing powders with a steep particle size distribution and sharp top size limitation in the range < 5 µm to 200 µm.
- Grinding nozzles arranged around the periphery of the grinding chamber
- Classifying wheel(s) arranged horizontally in the classifier top section
- Cool and contamination-free grinding
- Cleaning made easy by the hinge-back and removable classifier top section and the inspection deck in the mill housing
