Gas Atomizer AUG 1000 – 25000

Overview Gas Atomizer AUG 1000 – 25000

For fast and economic production of small to medium batches of metal powder

The Blue Power gas atomization plants have been particularly designed for the flexible and economic production of small to medium metal powder batches. Traditional large-scale production plants cannot provide this economic advantage as frequently changing alloys in production require high cleaning efforts to avoid cross contamination. Particularly in R&D or precious metal powder applications small amounts of various kinds of powder are frequently required, often also new types of alloy powder not available on the market.

Our atomisers produce spherical, flowable metal powders with mean particle sizes between ~1 and 200 µm for e.g. additive manufacturing, soldering or foam sintering processes, as well as MIM and other powder metallurgy procedures. To obtain specific metal powder characteristics, the  AU machines work with different easy-to-change nozzle systems: free fall and close coupled atomisation nozzles. Flow optimisation in the spray chamber ensures an increased powder quality (avoidance of satellites).

For numerous applications and a wide spectrum of alloys

The AUG machines are designed for numerous applications in the most diversity thanks to their narrow particle size distribution and high yield and the possibility of flexible usage provided by different nozzle systems. They are generally suitable for gas atomization of a wide spectrum of alloys; such as those based on Cu, Au, Ag, Sn, or Zn (standard versions) as well as Fe, Co, Ni, Pd, or Pt (high-temperature versions HT, HTC, and HTC+). The inductive heating takes place in graphite crucibles (up to 1600° C) or in ceramic crucibles: HT up to 1750º C, HTC up to 1850º C, HTC+ up to 2000º C. The crucible volumes reach from ~1.5 l to ~25 l. For the production of reactive materials like Al or Mg, please ask us for our solutions. 

Powder characteristics and particle sizes for every request

To obtain specific metal powder characteristics and particle sizes, the AUG machines work with different easy-to-change nozzle systems: free-fall and close-coupled atomization nozzles. Optionally, an anti-satellite system for highest sphericity is available.

 

Advantages 

Anti-oxidation features
The AU machines offer the possibility of oxidation-free processing in the closed-chamber machine by means of de-gassing, vacuum and protective gas features.

Gas flow optimisation
Increase of powder quality by gas flow optimisation in the spray chamber (avoidance of satellites)

Specific powder characteristics
by use of different atomisation nozzles and optional use of hot spray gas

Modular availability of free fall as well as close coupled atomisation nozzles to obtain specific metal powder characteristics. Fast and easy nozzle change.

Easy-to-clean concept
Polished stainless steel surfaces prevent powder adhesions in spray chamber, cyclone and collector – all parts are easy to clean without any residues.

Dynamic Differential Pressure system for constant metal mass flow
The DDP system is ensuring a constant and controllable metal mass flow, and therewith gas-to-metal ratio, independent from the melt level in the crucible.
