Confirm Powder Properties
Review composition, feed distribution, bulk density, moisture, oxygen sensitivity and explosion characteristics.
Nitrogen-Protected 3NAF100A verified Henan project used a 3NAF100 nitrogen-protected air classifier for aluminum powder with a reported D50 range of 8–45 μm and capacity of 300–400 kg/h.
The project required a broad adjustable D50 range of 8–45 μm at a reported 300–400 kg/h while processing aluminum powder under nitrogen protection.
For a comparable material, oxygen concentration, dust explosibility, gas purity, pressure control and safe collection must be reviewed alongside classification accuracy.
The reported values document one completed reference. A new metal-powder line should be selected from representative testing because particle shape, oxidation sensitivity, bulk density and feed distribution can change the result.
Review composition, feed distribution, bulk density, moisture, oxygen sensitivity and explosion characteristics.
Verify particle-size distribution, usable yield, fines recovery, system stability and gas demand.
Define protection gas, oxygen monitoring, pressure control, contact materials and collection arrangement.

A comparable aluminum-powder project can be engineered as a closed-loop inert-gas classification system with oxygen and pressure monitoring.
These values come from the authorized project record and describe this reference only. They are not a universal performance guarantee.
A new material should be tested before model selection because feed distribution, operating settings, safety requirements and product recovery all affect capacity and particle size.
The original report is displayed as supplied. No replacement curve or reconstructed particle-size distribution has been created.
