WATER ATOMIZERS FOR METAL POWDER PRODUCTION - ATOM

Water atomizers for metal for the production of precious and non-precious metal alloys powder, with controllable sizes from about ten microns up to a few millimetres.

 

The melting process can be carried out in air or a controlled atmosphere, as well as under vacuum or normal atmospheric pressure, thus allowing atomization of a wide range of metals including low temperature and/or easily oxidizable ones such as zinc, aluminum, copper, silver ...

TECHNICAL FEATURES:

  • Power range : from 30 kW to 250 kW
  • Production Capacity: from 10 to 300 Kg per cycle
  • Metals that can be melted: Gold, Silver, Platinum, Palladium, Copper, Zinc, Aluminum, and other base metals including alloys.

 This system is composed of:

  1. Metal melting unit by induction, optionally equipped with hood protection under controlled atmosphere
  2. Granulation die unit by induction
  3. Atomization unit equipped with a serie of adjustable nozzles
  4. Pressurization system of process fluids (water or gas) up to 250 bar, with pressure regulating system
  5. Powder/grain recovery system
  6. Recovery and filtration system of process water
  7. Two Medium frequency converters
  8. PLC control with touch-screen for all phases of the cycle
