Plants

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.

Level of development

The given technology is applied for solder powders production on pilot manufacture of UralNETRAMM.


The plant UR-5: General view.

The plant UR-5: System of gas purification.


The plant UR-5: System of powder unloading into hermetic package with argon.

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.
