Plants
The plant for production of powders
with amorphous structure and metal colours
The plant is intended for production fast-hardening
powders. On the plant it is possible to
produce amorphous powders from alloys
Fe-Nd-B, Fe-P-C and other, as well as
powder of aluminum, zinc and other metals
and alloys. The particles of such powders
have thickness 10-30 microns.

The given technology allows to produce
of powder for manufacture of metal colours.
It is alternative to produce of powders
with the scaly form by a method of mechanical
grinding by crushing. It has considerably
large output (up to 200 kg / hour), than
mechanical milling (up to 5 kg / hour).
Besides the mechanical milling does not
allow to produce scales from metals exposed
to a mechanical hardening, for example,
from zinc. These colours are used for
protective and decorative covering. Fast-hardening
powders are used also for production of
magnets with a high magnetic field energy
or materials with a high corrosion-resisting.
It is new technology. We just have completed
its tests on different metals and alloys
(Sn-Pb, Zn, Al, Fe-P-C).
