Plants for production of powders
by gas (GA) and water (WA) atomisation.
The plant GA is intended for production
of powders from metals and alloys with
a melting temperature up to 1600 °Ñ. It
is possible to realize atomisation by
compressed air, high-pressure inert gases
(argon, nitrogen) from the evaporator
or from the ramp. The system contained
cyclone collectors and filters is used
for clearing of exhaust gas. The plants
can be supplied with a recirculation system
to reuse inert gas. Inductive fusing of
metal can be also realized on air under
a layer of a flux or in environment of
inert gas. Capacity of a crucible is from
10 up to 400 kg. The given plant allows
to produce powders of aluminum, silver,
copper, brass, bronzes, iron, doped alloys
with output up to 1000 kg per hour. Sizes
of powder particles are 30-100 microns.
The overall dimensions of GA plants depend
on volumes of production, height - 6 m,
working area isn't less than 100 m2.
The WA plant is intended for production
of powders from metals and alloys on a
base of aluminum, silver, gold, manganese,
silicium, copper, cobalt, iron, nickel
and other. Ñapacity of a crucible on plant
can be from 5 up to 250 kg. At water atomisation
high-lift pumps are used. By high-pressure
water atomisation it is possible to receive
powders with output up to 500 kg / hour.
After atomisation the powder is exposed
to a water removal and drying. The powder
has size from 10 up to 500 microns. The
shape of particles is improper, however
such powders are well molded and pressed.
The WA plants have small overall dimensions
and reliability in operation.
UralNETRAMM cooperates with English company
ASL and German IWT in the matter of deliveries
of the GA and WA plants. Therefore delivery
of these plants made by ASL and IWT is
possible. Mounting, starting and adjustment
works will carry out by UralNETRAMM.
