FIELD: textile, paper.
SUBSTANCE: device is intended for use in paper-and-pulp industry. Invention is based on at least two refiners arranged so that mixture of chipped wood, water and steam is initially supplied to refiner 1, where chipped wood is milled and the whole mass flow is supplied to refiner 2 for fibre refining to the final degree of particle fineness. Mass flow consisting of steam and fibre is supplied to at least refiner 1 due to the energy from refiner rotor rotation, so no essential reverse flow of steam is occurred. Mass flow ensuring operation refiner 1 is fully supplied to refiner 2. Besides steam is not separated from mass before refiner 2.
EFFECT: low energy consumption per one ton of products.
