INSTALLATION FOR PRODUCTION OF THE GRANULES BY THE CENTRIFUGAL SPUTTERING OF THE MELT METAL Russian patent published in 2008 - IPC B22F9/10 

FIELD: non-ferrous metallurgy industry; other industries; device for production of the granules of the non-ferrous metals.

SUBSTANCE: the invention is pertaining to production of the granules of the non-ferrous metals including the chemically active calcium or magnesium and their alloys by the centrifugal sputtering. The installation contains the melting furnace, the hermetic chamber of granulation with the cover, the electrically heated melt metal conduit, the dispenser made in the form of the perforated container with the drive of rotation, the granules collection container, the compressor and the heat exchanger. The metal conduit is made in the form of the lift tube, one end of which is located in the melting furnace with formation of the liquid metal gate out of the melt of the granulated metal, and the other end is placed in the granulation chamber. The drive of rotation of the dispenser is made in the form of the gas-turbine engine with the closed system of the gas pipelines of circulation of the noble gas from the engine into the hermetic container and further into the heat exchanger and the compressor. The engine is mounted on the hermetic container disposed in the chamber of granulation along its center coaxially with the melt metal conduit and the dispenser. The dispenser is located on the shaft of the gas-turbine engine. The invention will allow to increase the efficiency of the granules production and the outlet of the metal into the target product of any preset granulometric composition and also to reduce consumption of the noble gas.

EFFECT: the invention ensures the increased efficiency of the granules production and the output of the metal into the target product of any preset granulometric composition, and also reduction of consumption of the noble gas.
