FIELD: mechanical engineering, in particular, equipment for grinding of various materials. ^ SUBSTANCE: disintegrator has casing equipped with cover and incorporating rotating disk with concentric rows of fingers, between which finger rows are positioned concentric rows of fingers fixed on immovable cover, charging funnel and discharge branch pipe. Within charging funnel are provided at least two ribs for orienting of ground material in direction approximating funnel axis, and are secured sectioned annular flat movable and immovable knives for preliminary grinding of material into parts having sizes smaller than length of fingers. Rotating disk is equipped with blades for removal of ground material and reducing content of dust particles in ground material. ^ EFFECT: increased efficiency in grinding of hollow articles and reduced consumption of power for grinding process. ^ 3 dwg
