ABSTRACT:
Disclosed is a crusher. A material is sucked in an upper part on one side of a case part which is formed by horizontally coupling a plurality of cases. The sucked material is horizontally moved and discharged to a lower part on other side. A driving force of a motor is transferred to a side of a rotary shaft which passes through the center from one side to other side of the case part. The crusher includes: a rotary blade part for maintaining an interval from an internal peripheral surface of a central part of the case part and being fixed to a central part of the rotary shaft and rotated in one direction to generate a turbulence in multiple stages; a ring gear part being fixed to an internal peripheral surface of the center of the case part and maintaining a gap from a circumference of the rotary blade part to form a crushing zone in multiple stages; and a discharging fan being fixed to other end part of the rotary shaft and rotated in one direction to discharge a completely crushed grain.
