As described above, according to the cutting rotor of the present invention, the fine particles and particles cut by the cutting blade unit are discharged from the cutting edge smoothly and efficiently through the tunnel to the outside of the cutting rotor. Therefore, the amount of cutting per unit power consumption increases significantly. In addition, the retention of fine particles and granular materials under the blade edge is eliminated, and the blade edge during rotation is effectively cooled, and good blade sharpness can be maintained for a long time. If the cutting rotor has a steel plate welded structure, the rotor can be weighed and the rotor and the crusher can be increased in size.
