Aquatic feed additive crushing and dust removing device

The invention discloses an aquatic feed additive crushing and dust removing device in the technical field of environmental protection and dust removal. The device comprises a dust removing barrel, and a dust suction opening is rotationally connected to the upper portion of the dust removing barrel; a circulating mechanism is arranged above the dust removal barrel and is used for sucking outside air into the dust removal barrel through the dust suction port and then discharging the outside air; a supporting frame is fixedly connected to the upper portion of the dust removal barrel, and a driving mechanism is arranged on the supporting frame and used for driving the circulating mechanism to operate. A dust removal mechanism is arranged in the dust removal barrel and used for removing dust in air entering the dust removal barrel from the outside in a water spraying and dust falling mode. The device is simple in structure and convenient to use, dust generated when the feed additive pulverizer works can be effecti
