FIELD: loading loose materials in chemical, oil refining, and other industries such as primary reforming reactors. SUBSTANCE: proposed method ensures that each particle easily falls within tube by gravity and reaches surface of layer being formed at constant speed equal for all particles and lower than free-fall speed at which particles may disintegrate due to collision with particles of layer being formed. This free-fall speed of particles is set within tube by retarding them with aid of opposing gas flow supplied to bottom part of tube interior not charged with particles through flexible hose whose external end is connected to compressed-gas source. Particles are introduced into space between tube wall and hose lengthwise of the latter and as tube is filled up with particles, mentioned hose is lifted up in proportion with amount of charged particles. Device implementing proposed method has intake bin; trough connected on one end with outlet of mentioned bin and on other, with tube being charged; drum which is free to rotate about its axis; drive designed to set mentioned drum assembled with hose into rotary motion; drive control unit; flexible gas-conveying hose wound on mentioned drum and connected by its end secured on drum with gas source through gas flow governor. Proposed method and device provide for uniform distribution of particles throughout height of tube being charged which makes it possible to form bulk layer of homogeneous structure and similar hydraulic resistance for any number of tubes. Device provides for eliminating hose clogging with particles being loaded and their disintegration as free-fall speed of particles within tube is chosen for each particular type of particles to ensure safety by controlling air flow retarding their fall in tube. EFFECT: improved uniformity of particle layer through height similar for any number of tubes charged simultaneously; enhanced loading speed. 7 cl, 1 dwg, 1 ex
