Camphor crushing device

The utility model discloses a camphor crushing device, which belongs to the technical field of crushing devices and comprises an induced draft fan, a crusher and a first cyclone separator. The device further comprises a second cyclone separator and a first feeding mechanism. The second cyclone separator is connected with the upper end of the first cyclone separator, and the second cyclone separator is connected with the induced draft fan. In the working process, after camphor powder with the fineness not meeting the use requirement falls into the first feeding mechanism from the lower end of the first cyclone separator, the first feeding mechanism can convey crude camphor powder into the smashing machine to be smashed again, and the camphor powder with the fineness not meeting the use requirement can be conveyed into the smashing machine to be smashed again; and when the fineness of the camphor powder crushed by the crusher does not meet the use requirement, the camphor powder can be continuously fed into the
