FIELD: process engineering.
SUBSTANCE: invention relates to production of inorganic fine fillers to be used in various industries, in particular, for production of spheroidised polydisperse powders. Initial raw components of inorganic powders of mineralogical composition and dispersity of up to 1 mm including organic inclusions into plasma generator chamber to be processed therein in plasma flow to spheroidised particles. Note here that processing in plasma flow is carried out at 100 kVA. Produced product is then cooled down and discharged Cooled micro ball-shaped product is classified at plasma generator outlet to preset properties for further use.
EFFECT: expanded dispersity range of initial raw stock, simplified process.
