PURPOSE: A grain pulverizer with bypass passageway is provided which prevents fine dust from flowing in an inner part of main body by forming a separate air bypass passageway so that the grain pulverizer is not broken down by fine dust or husk accumulated inside the grain pulverizer. CONSTITUTION: In a grain pulverizer comprising a screw(14) for transferring grain injected into injection port(12) during rotation of transfer motor(16), and a pulverizing impeller(26) for rotating the grain transferred to the hopper by transferring the grain transferred by the screw(14) to hopper(15) so that the grain is pulverized to fine powder and transfer the pulverized grain to discharge chute(37) at a lower side so that the discharge chute(37) discharges the pulverized grain to the outside, the grain pulverizer with bypass passageway comprises opening holes(31a,31b) formed at an upper part of the discharge chute(37) and one side of the hopper(15); an air bypass passageway(34) that is bypassed with being connected to the two opening holes(31a,31b) so that air pressure generated inside the grain pulverizer is circulated; fixing plates(33a,33b) to which the air bypass passageway(34) is fixed so that the air bypass passageway(34) is connected to the fixing plates(33a,33b); and filtering meshes(32a,32b) mounted on an inner part of the fixing plates(33a,33b) so that air passes through the filtering meshes(32a,32b) while grain powder is blocked by the filtering meshes(32a,32b).
