Preliminary crusher for fluorite powder production

The utility model discloses a preliminary crusher for fluorite powder production, which relates to the technical field of fluorite powder production and comprises a mounting bottom plate, four corners of the bottom of the mounting bottom plate are connected with supporting legs through bolts, the top of the mounting bottom plate is connected with a barrel through bolts, and the top of the barrel is slidably connected with a crushing barrel through a rotating shaft. And a barrel body of the crushing barrel is located in the barrel body, a crushing mechanism is arranged at the bottom of the crushing barrel, and a driving mechanism is arranged on one side of the crushing barrel. The fluorite ore crushing device can be overturned in the crushing barrel which rotates continuously when encountering relatively flat fluorite ore, so that the situation that the fluorite ore is placed is avoided, in addition, the inclination angle of the auxiliary crushing blade is smaller than that of the main crushing blade, the fluo
