FIELD: processing of ground materials. SUBSTANCE: method involves producing fluid powder containing particles of carrier material covered with coating composition; providing flow of liquid coating drops; supplying conveyance gas with particles to be coated; supplying drying gas into drying chamber, with contact between coating and particles being conducted in such a way that drying gas is prevented from early contact with coating. Coating of particles is effectuated by means of spraying-drying or spraying-cooling unit with spraying device of high-pressure spraying nozzle or spraying wheel type. EFFECT: increased efficiency, improved quality of coating. |
