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

FIELD: process engineering.

SUBSTANCE: invention relates to production of spherical powders for small arms. Proposed method comprises mixing the components in reactor, preparing powder lacquer in ethyl acetate, dispersing in the presence of adhesive and ethyl acetate distillation. Note here that powder lacquer is dispersed in reactor by blade mixer, mixer blades being arranged in 3-4 rows on reactor shaft and inclined at 90 degrees to each other. Blade width makes 0.07-0.12 of mixer diameter while its thickness equals 0.007-0.008 of mixer diameter. Blade feature variable inclination angle with respect to horizontal plane at six regularly spaced points over blade length starting from mixer hub.

EFFECT: higher yield of powder target fraction due to uniform grinding, constant rates of dispersed medium flow.
