🔹 **INTENDED USE PER OEM**
The air classification mill reduces dry friable materials to a sub-sieve range by fluidizing particles for precise separation.
Material enters the grinding chamber via a screw feeder with a variable speed drive, where controlled airflow lifts fines into the classifier zone.
Oversized particles are rejected or recirculated for further reduction, while classified fines move to the integral fan chamber and are pneumatically conveyed to a dust collection system, typically a cyclone with a backpressure dust filter.
