FIELD: technological processes. ^ SUBSTANCE: suggested method includes the following stages: (a) spraying of emulsion, solution or suspension, which contain dissolvent and basic material, through the sprayer into primary drying chamber for making of drops, which contain dissolvent and basic material; (b) evaporation in primary drying chamber, of at least some part of dissolvent into drying gas for solidification of drops and formation of particles, dispersed in drying gas; and (c) passage of particles and of at least part of drying gas through jet mill for deagglomeration and grinding of particles. Combination of spraying drier with parallel jet grinding provides for single-stage method with simultaneous equipment operation. ^ EFFECT: processing time is reduced as well as technology cost at the high quality of produced powders. ^ 42 cl, 3 dwg, 13 tbl ^ id8027583 |
