DEVICE FOR MAKING POWDER AND AXIAL-FLOW SPRAYING Russian patent published in 2012 - IPC B22F9/10 B22F9/14 

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy, particularly, to production of metal powders. Proposed device comprises chamber with accumulator of blanks and blank feeder, drives of blank rotation and translation, spraying chamber with plasmatron directed to blank end face and powder intake, all said components being tightly interconnected. Powder intake is equipped with blower-feeder. Spraying chamber is equipped with coarse particle deflector and sieving machine arranged ahead of intake. Drive of blank rotation is composed of hollow vertical spindle with bowl-shape disc on top face and clamping cams arranged directly under said disc. Drive of blank translation is composed of pusher arranged under spindle and aligned therewith. Spraying chamber is shaped to lens and oriented horizontally so that its axial line and those of plasmatron and spindle are aligned.

EFFECT: lower production costs, higher yield and quality.
