[0022] A feeding port 2 is fixedly connected to the upper side of the device body 1 , and raw materials can be fed into the device body 1 through the feeding port 2 for crushing.

[0023] The crushing blade 5 is rotatably connected to the device body 1, and the crushing blade 5 is located inside the crushing box 3. A discharge valve 6 is fixedly connected to the bottom of the crushing box 3, and the discharge valve 6 is close to the rotating shaft of the No. 1 screen plate 7. The crushed debris can be discharged through the discharge valve 6.

[0024] The vibration mechanism includes a rotating rod 11 and a stop plate 12. The rotating rod 11 is fixedly connected to the second motor 10, and is rotationally connected to the device body 1. The stop plate 12 is fixedly connected to the rotating rod 11, and is in contact with the bottom of the first sieve plate 7.

[0027] The working principle of a pulverizing device for producing feed additives based on the embodiment is that when it is used, the raw material is put into the pulverizing box 3 through the feeding port 2, and then the No. 1 motor 4 is operated to make the pulverizing blade 5 rotate rapidly for pulverization, and then the material is discharged through the discharge valve 6 to make it contact with the No. 1 screen plate 7.

In the second screening process, the crushed materials that fail to pass the No. 2 screen plate 17 will follow the No. 2 screen plate 17 to slide to the external No. 1 collecting box 19 for collection, so as to carry out secondary crushing treatment, and the crushed materials that can pass the No. 2 screen plate 17 will directly fall into the No. 2 collecting box 20 at the bottom for collection and discharge. This two-stage screening design can ensure the uniformity of the particle size of the raw materials, reduce the difficulty of subsequent work, and improve the overall quality of feed additives.
