The present invention relates to a crusher comprising: a housing whose upper part is opened an insert container in the form of a cylinder embedded in the housing and having an inlet to allow waste to be inserted a cover for opening and closing the inlet a first side crushing unit arranged in the lower part inside the insert container, and having an outer circumferential surface in the form of a disk embedded in the inner circumferential surface of the insert container, and an inner circumferential surface in the form of a disk with a side blade, and for crushing waste inserted into the crushing container by using the side blade a rotary shaft formed to be protruding while passing through the lower surface of the insert container a first motor for allowing the rotary shaft to rotate a first rotary plate for inducing waste inserted inside the insert container to a first side crushing unit by at least one first induction blade formed in one side while a plate in the circular form formed to be smaller than a circumference of the insert container is mounted on the rotary shaft and rotated a water supply pipe having a pipe in one side of the housing and receiving external water at least one first injection nozzle and a motor for injecting water received by the water supply pipe in a direction of the cover and a control unit for controlling the first injection nozzle. In addition, a discharge pipe is formed in the inclined lower surface of the insert container, and crushed waste is mixed with water injected from the injection nozzle. Then, the crushed waste flows down into a gap between the first rotary plate and the first side crushing unit, thereby discharging the crushed waste to an outside through a discharge pipe.COPYRIGHT KIPO 2016본 발명은 분쇄기에 관한 것으로, 상부가 개방된 하우징, 하우징에 내재되고 쓰레기가 투입되도록 투입구가 형성된 원통 형상의 투입통, 투입구를 개폐시키는 덮개, 투입통 내측 하부에 배치되고, 원판형상의 외주면이 상기 투입통의 내주면에 내제되고, 원판형상의 내주면은 측면날이 형성되어 분쇄통으로 투입된 쓰레기들을 측면날로 분쇄시키는 제1측면분쇄부, 투입통 하부면을 관통하면서 돌출되게 형성된 회전축, 회전축을 회전시키는 제1모터, 투
