The utility model discloses a multi-shaft pulverizer which comprises a pulverizer body, a feeding port is formed in the upper portion of the pulverizer body, a first pulverizing shaft is rotationally installed in the pulverizer body, a fourth pulverizing shaft is rotationally arranged in the feeding port, and one end of the first pulverizing shaft is in transmission connection with one end of the fourth pulverizing shaft through a belt. One end of the first crushing shaft is connected with fan blades, and the other end of the first crushing shaft drives the second crushing shaft and the third crushing shaft to rotate synchronously through the gear box. The crushing cutters on the first crushing shaft, the second crushing shaft, the third crushing shaft and the fourth crushing shaft are mutually staggered to form a plurality of cross points, so that the relative speed between the blades is obviously improved, materials can be more effectively crushed, particularly for tough materials, the crossed blades can timely knock off the materials wound on the cutters, and the crushing efficiency is improved. The materials are prevented from performing circular motion along with the crushing shaft, so that the crushing efficiency is greatly improved.
