The plants for production of powders
by Centrifugal-Pneumatic Atomisation (CPA)
The plant is intended for production of
fine powders by a method of a centrifugal
- pneumatic atomisation (CPA). It is made
in laboratory (UR-2) and industrial (UR-5)
versions. On the industrial version of
the plant it is possible to make powders
of tin, zinc, aluminum, lead, copper and
solders Sn50Pb50, Sn61Pb39, Sn63Pb15Ag2,
soldering alloys on the basis of copper,
zinc, aluminum. The plant is provided
with a system of cyclone collectors and
filters for clearing of exhaust gas from
dust fractions and recirculation system
to reuse inert gas. The plant can be completed
by a system of computer control and video
to supervise a process of atomisation.

The given technology is already applied
for fine powder production of alloy Sn-Pb,
Sn-Ag, Zn used for preparation of pastes
for soldering electronic components and
in an dental materials. Firms that make
pastes to solder units for production
of portative computers, radiotelephones,
other devices and equipment are interested
in acquisition of such powders or plants.
