METHOD OF MAKING SPHERICAL POWDER FOR SMALL ARMS Russian patent published in 2014 - IPC C06B21/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to production of spherical powders for small arms. Proposed method comprises introducing water-squeezed-out graphite suspension in spherical powder, feeding said powder with graphite into air line by compressed air pressure wherein powder is dried and graphitised. Spherical powder after water squeezing is fed into auger feeder bin equipped with vibrator wherefrom it is fed by auger into the chamber of ejector composed of pipeline furnished with nozzle at its end. Said powder is fed in airflow into mixing chamber, said airflow with spherical powder is expanded and, further, via pipeline fed for final drying.

EFFECT: lower costs, automated graphitisation phase.
