FIELD: construction, chemical, pharmaceutical, food-processing and other branches of industry. SUBSTANCE: method involves forming enclosure during passage of granular material and capsulating substance through cylindrical chamber movable at frequency of 120-600 rev/min along circle whose center is offset relative to chamber axis for distance of 0.1-0.5 of chamber diameter. Granular material and capsulating substance are supplied at an angle of 15-60 deg to chamber onto its inner surface in direction of movement of chamber. Method allows dense and stable enclosure-capsule of uniform thickness to be applied on surfaces of superlight, light and heavy granular materials. EFFECT: increased efficiency, wider operational capabilities and improved quality of capsulated materials. 2 cl, 1 tbl
