Principle of Operation:

The system operates on the air jet sieving principle, wherein:

1. A controlled negative pressure vortex is generated.
2. Powder is dispersed through a rotating nozzle across the sieve surface.
3. Fine particles pass through the sieve and are collected.
4. Coarser particles remain on the sieve.
5. Continuous airflow prevents mesh clogging, ensuring high accuracy and repeatability.
