PRODUCTION OF TITANIUM PELLETS Russian patent published in 2016 - IPC B22F9/14 

FIELD: process engineering.

SUBSTANCE: cylindrical biller is revolved about horizontal axis to fuse the billet end by arc plasmatron plasma jet so that fused particles are sprayed by centrifugal forces and solidified at flight in the medium of working gases. The hot mix of said working gases is bled from the spraying chamber. Then, it is forced into primary purification filter and, further, into superfine filter. Then, cleaned mixed is forced via the heat exchanger into the compressor and, therefrom, into the receiver. Said mix is forced into the cooler to feed the cooled mix into cooled mix flow generator. The cooled working gas mix flow is generated by forcing it through the flow generator and into the spraying chamber to cool said fused particle by said cooled working gas mix flow. Now, the pre-cooled pellet particles are dumped into the intake hopper.

EFFECT: lower temperature in the spraying chamber, higher cooling rate, better heat removal.
