Centrifugal Atomiation Equipment
1. Introduction
Molten metal flows into the center of rotating disk from melting
device through guiding device, then scatters along radial
distribution and forms a thin liquid film one the rotating disk
under the effects of inertia and centrifugal casting. When liquid
film reaches the edge of rotating disk, it will be atomized into
liquid drops, then these drops are solidified into powders.
It’s not necessary to use protective atmosphere in the melting
process. High quality powders with uniform particle, good fluidity,
proper arrangement and without hollow is achieved by adjusting
atomizing temperature, rotation speed of rotating disk, nozzle
geometrical morphology, spraying angle, etc.
This equipment is suitable to produce various low melting metal and
alloy powders, such as solder, Al powder, Mg powder, etc. It also
produces spherical or cone-shaped powders.
2. Features
(1)It’s suitable to produce low melting metal and alloy powders for
battery material, accelerant, metal injection moulding and 3D
printing.
(2)Good fluidity and arrangement.
(3)Less production cost and procedure; high quality powder with
uniform particle.
(4)Easy operation and maintenance;
(5)Rotation speed of the rotating disc is 10000~40000rpm. Daily
output is up to 2t.
(6)Now the equipment we developed is suitable for producing high
melting and ultrafine metal powders. Melting temperature is up to
1750℃. High-speed electric machine is 60000~120000rpm.
