Rotating Disk Centrifugal Atomization Equipment

Overview and principle:
RDGA vacuum rotating disk vacuum gas atomization equipment is for metal powder manufacturing. It’s used for R&D institution and universities to study the spherical and semi-spherical high temperature alloy powders.
Working principle:
Melt alloy under proper vacuum conditions. The liquid metal flows down through diversion tube and falls onto high speed rotating disk. Then the liquid metals distribute in radial directions and form a layer of metal thin film on the disk. With inertial and centrifugal force, the thin film arrives at the edge of disk and is atomized to droplet. These tiny liquid drops will solidify during flying. The mixture of powders and air will be sent to the cyclone separator via the convener pipe. And the rough powders and fine powders as well as atomizing gas will be separated in the separator. The metal powders will be collected in the sealed container.
Application: water atomizer is suitable for producing irregular metal powders and are widely used in powder metallurgy, diamond tools, sealing materials, electrical copper powder heat conduction materials, conductive materials, welding materials, Superhard material, friction materials, pharmaceutical and chemical industries.
