PURPOSE: A rotor for a pulverizer is provided to efficiently implement pulverization, improve the durability of the pulverizer, and improve work efficiency. CONSTITUTION: A rotor for a pulverizer is equipped with a rotary cutter(100) and a cutter fixing member(200). The rotary cutter is equipped with pulverizing blades. The cutter fixing member is equipped with a central hole(201) into which a rotary shaft is inserted, and plural cutter coupling parts(202) to which the rotary cutters are coupled. Each cutter coupling part is equipped with a bottom surface in contact with one surface of the rotary cutter, a side surface(211) in contact with another surface of the rotary cutter, and a groove(212) placed on a section in which the bottom surface and the side surface meet each other. The pulverizing blade is formed on each edge of the rotary cutter so that the coupling direction of the rotary cutter is capable of being converted. The cutter fixing member is further equipped with the first and the second inclined surface(220,221). The first and the second inclined surface are formed to be downwardly inclined between two adjacent cutter coupling parts among the cutter coupling parts, and converge toward each other. The one surface and another surface of the rotary cutter are mutually vertical, and the bottom surface and the side surface of the cutter coupling part are mutually vertical. The rotor is further equipped with first holes(301) formed on the rotary cutter, and fastening bolts(300) fastening the rotary cutter to the cutter coupling part through second holes formed in the cutter coupling part.
