In a three axes type crushing device, an area where a finely fragmenting blade rotary structure receives fragments is enlarged, and a blade clearance between a stationary blade and a finely fragmenting blade is adjusted relatively easily. A roughly fragmenting unit includes a pair of roughly fragmenting blade rotary structures (1), each having a large number of roughly fragmenting blades (2) with clearances substantially corresponding to thicknesses of the roughly fragmenting blades. The roughly fragmenting blade rotary structures are supported to be rotatable inward relative to each other and to be located such that the roughly fragmenting blades of one roughly fragmenting blade rotary structure enter the clearances between the roughly fragmenting blades of the other roughly fragmenting blade rotary structure, and the material nipped by the roughly fragmenting blades is cut by blade portions of opposing roughly fragmenting blades to be roughly fragmented into fragments, which falls downward. A finely fragmenting unit disposed below the roughly fragmenting unit includes a finely fragmenting blade rotary structure (9) having a large number of finely fragmenting blades (92) which finely fragments the fragments in cooperation with a stationary blade (10). The finely fragmenting blade rotary structure is disposed at such a position that makes a center normal line thereof (L1) offset in a lateral direction relative to a center normal line (L2) of a cutting portion constructed by the roughly fragmenting blades of the roughly fragmenting blade rotary structures. The stationary blade is disposed in the offset direction, and the finely fragmenting blade rotary structure is rotated in a direction toward the stationary blade.
