Air classification separates a feed into defined particle-size fractions. A project may remove coarse particles, reduce excess fines or produce a narrower size band, with collection paths selected for each fraction.
Classification uses the balance between aerodynamic drag and centrifugal separation around a rotating classifier. Its cut point depends on the material as well as operating conditions.
Engineering notes describe the process and evaluation requirements. Project-specific supply boundaries and acceptance results are established in the agreed technical documentation.
Single-stage or multi-stage arrangements are evaluated according to the required product band. Coarse material may be retained, returned for grinding or collected separately; recirculation is a process decision.

A narrow size distribution should be checked with both the fine and coarse tails of the distribution. A single D50 value does not establish the width of a product band.

Recovery, separation sharpness and throughput must be evaluated together under the same feed and operating conditions.

Morphology Control
Particle shaping combines controlled impact, friction and classification to adjust particle edges and morphology. This equipment record introduces the shaping route, its supporting systems and the information required to evaluate a similar application.
View caseBattery Materials
Controlled jet pulverization adjusts processing intensity for powders that need deagglomeration or limited size reduction. The route is evaluated against oversize removal, fines generation, particle integrity and contact-material requirements.
