Meaning
Secondary gas delivery systems introduce a controlled flow into the atomization chamber to carry fine powder particles toward the collection filters. Sweep gas injection prevents the accumulation of fine powder on the chamber walls and reduces the risk of particle re-melting. This continuous flow also helps to cool the chamber and maintain a stable internal pressure during the run.
Sourcing managers check for this feature to ensure high powder recovery rates.
Carrier Flow
The sweep gas flows along the internal surfaces of the chamber to create a protective barrier. This barrier prevents hot droplets from sticking to the metal walls.
Powder Recovery
Efficient powder transport reduces the amount of material left behind in the atomization chamber after a batch is completed. This reduction improves the overall yield of the process.
Safety Factor
Continuous gas movement prevents the formation of static powder clouds, which reduces the risk of dust explosions. This flow is necessary when processing highly reactive metals.
