METHOD OF PRODUCING SPHERICAL POWDER Russian patent published in 2013 - IPC C06B21/00 B01F7/04 

FIELD: weapons and ammunition.

SUBSTANCE: proposed method comprises mixing of components in reactor, preparation of powder lacquer in ethyl acetate, dispersion in the presence of glue and solvent distillation. Note here that powder lacquer dispersion is performed in 6.5 m³ blade mixer with variable inclination blades arranged in 3-4 rows at the shaft bottom extension at 90 degrees to previous blade. Shaft top extension runs in two radial spherical bearings and one thrust bearing fitted in the column. Flow spreader is arranged at reactor powder and rigidly secured at the rod to direct flow of formed cone to shaft center. Formation of powder lacquer and its granulation is performed at 60-120 rpm of aforesaid mixer. Reactor is heated by heat carrier fed into its jacket. Shaft is sealed by cooled gland. Finished suspension is discharged from reactor by gravity via remote control discharge valve while discharged suspension bulk is filled with nitrogen.

EFFECT: higher yield of target fraction, preset parameters of powder particles, safe process.
