FIELD: production of free-flowing powder containing particles of carrier material with coating; may be used in various branches of national economy. SUBSTANCE: used for particle coating is spray drier or spray cooled with means for spraying in the form of high-pressure spraying nozzle or spraying wheel. The method provides for creation of flow of droplets of liquid coating, supply of transporting gas with particles to be coated, and supply of drying gas to drying chamber. Contact of coating material with particles to be coated is effected so as to prevent premature contact of drying gas with coating material. EFFECT: higher efficiency. 18 cl, 4 dwg, 1 tbl
