[0002] Iron ore is an important raw material for steel production enterprises. Natural ore (iron ore) is gradually separated from iron through crushing, grinding, magnetic separation, flotation, gravity separation and other processes. Iron ore is a mineral aggregate containing iron or iron compounds that can be economically utilized. After the iron ore is mined, it generally needs to be crushed, pulverized or even ground before it can be used.

[0003] According to the description of an iron ore grinding device disclosed in the patent website (authorization announcement number: CN 216172781U), "the utility model belongs to an iron ore grinding device in the field of iron ore processing, including a box body and a drying mechanism, two hydraulic telescopic rods are fixedly connected to the left and right sides of the top of the box body, and the tops of the two hydraulic telescopic rods are fixedly connected to a moving plate, and the output end of the first drive motor is fixedly connected to a grinding disc, and a grinding groove is provided on the top of the box body, and a grinding plate is fixedly connected in the grinding groove. A plurality of stirring rods are fixedly connected to the stirring shaft, and a mesh screen is fixedly connected to the box body. Four fixed rods are fixedly connected to the inner wall of the box body, and a third drive motor is fixedly connected between the four fixed rods. The output end of the third drive motor is fixedly connected to an induced fan, and a heating rod is fixedly connected to the inner wall of the box body. A heating wire is fixedly sleeved on the heating rod. An air outlet pipe is fixedly connected between the top of the box body and the box body, and an air inlet pipe is fixedly connected to the bottom of the box body; this device can automatically grind iron ore, and has good grinding efficiency and strong stability, and can also stir and dry the ground iron ore powder."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the second drive motor drives the stirring rod to rotate to stir the iron ore powder, thereby improving the drying efficiency. At the same time, the screening effect of the mesh screen can further screen the iron ore powder, which is beneficial to improving production quality. However, in actual use, as the mesh screen screens the iron ore powder for a long time, it is easy for larger iron ore powder to get stuck inside the mesh screen, thereby causing the mesh screen to be blocked, affecting the subsequent iron ore powder screening work. It has certain limitations, and therefore it is necessary to improve a grinding and extraction device for iron ore to solve the above problems. Utility Model Content
