[0002] In the mining, cement, building materials, chemical and other industries, ball mill is a commonly used grinding equipment, which uses steel balls as grinding media to crush and grind materials. During the use of ball mill, the steel balls will gradually become smaller due to wear, impact and other reasons, and eventually form waste steel balls.

[0003] The traditional way to deal with scrap steel balls is to transport them to a processing area for centralized treatment. However, these scrap steel balls are usually mixed with ground materials (such as iron minerals). The iron minerals gathered together are also a considerable amount. In order to save resources and costs, the iron minerals and scrap steel balls need to be screened and recovered. However, the amount of scrap steel balls is particularly large, and manual screening requires a lot of manpower input, the recovery rate is slow, and the consumption cost is too high. When using screening machinery for screening, the input of a large amount of scrap steel ball materials is prone to blockage, resulting in slow processing of the screening machine, poor screening effect, and inability to completely separate the scrap steel balls and iron minerals. Therefore, a ball mill scrap steel ball recovery system is needed. Summary of the invention

[0025] In some embodiments, the diameter of the separation plate 35 is smaller than the diameter of the guide plate 34, and limiting plates 351 are provided on both sides of the separation plate 35. The separation plate 35 is formed by two inclined straight plates connected together. An arc portion 341 is provided at one end of the guide plate 34 close to the separation plate 35. Two guide bars 342 are provided on the guide plate 34, and the two guide bars 342 are arranged in an eight-shape. The length of the two guide bars 342 close to each other is consistent with the length of the impact plate 362.

[0026] Working principle: During operation, the operator pours the material into the lower hopper 12, and the material is transported from the lower hopper 12 to the conveyor belt 23 through the discharge chute 14. During the material discharging process, the vibrator 15 drives the lower hopper 12 to vibrate, and the discharge chute 14 also vibrates under the action of the spring hook 13, thereby accelerating the material discharging speed. If the discharge chute 14 is blocked, the operator can swing the rotating plate 16 up and down to allow the material to be transported to the conveyor belt 23 faster. After that, when the material is transported on the conveyor belt 23, the groove 26 can help the scrap steel balls in the material to be transported more stably. At the same time, the baffle 25 can also limit the material to prevent the material from falling. When the material is transported to the driven roller 24, the conveyor belt 23 and the screening module are tilted as a whole. It can make the scrap steel balls and iron minerals slide down smoothly. Under the influence of the magnetic force of the driven roller 24, most of the iron minerals are affected and fall from the side of the separation plate 35 close to the second screen 33, and fall onto the guide plate 34 after passing through the second screen 33, and finally slide from the guide plate 34 to the first screen 32, and then fall into the storage box 4. When the iron minerals fall from the side of the separation plate 35 close to the second screen 33, some scrap steel balls with more iron minerals attached will also slide down to the second screen 33 due to the influence of the magnetic force of the iron minerals on the surface, and hit the clapper 362. The clapper 362 is restricted by the torsion spring and effectively blocks the scrap steel balls with more iron minerals attached, so that the iron minerals on the surface of the scrap steel balls with more iron minerals attached fall down after being hit. The waste steel balls separated from the iron minerals are temporarily stored at the clapper board 362, while most of the waste steel balls without much iron minerals will fall from the side of the separation plate 35 away from the second screen 33, and will be blocked by the cleaning brush 37 while falling, so that the waste steel balls without much iron minerals will slide down intermittently along the guide plate 34, and at the same time, the cleaning brush 37 will sweep down the small amount of iron minerals adhered to the surface of the waste steel balls without much iron minerals, so as to ensure the complete recovery of the iron minerals. Then, batches of waste steel balls will get acceleration from the arc portion 341 of the guide plate 34 and rush straight down, and under the guidance of the two guide strips 342 in the shape of an eight, they will hit the collision plate 363, so that the collision plate 362 and the clapper board 36 1 swings with the connecting shaft 361 as the axis, and further shakes off the iron minerals attached to the surface. Then the clapper 361 claps the scrap steel balls temporarily stored at the clapper 362. The mesh diameter of the second net frame 331 is slightly larger than the diameter of the scrap steel balls, and can temporarily support the scrap steel balls with more iron minerals attached to prevent them from falling from the second net frame 331. After being clapped by the clapper 362, the scrap steel balls temporarily stored at the clapper 362 fall from the second net frame 331 to the guide plate 34. During this period, they are affected by the mesh fluctuation of the second net frame 331 and the impact of falling on the guide plate 34, and the iron minerals attached to them are removed. Finally, all the scrap steel balls and the separated iron minerals will enter the first net frame 321 from the guide plate 34.The waste steel balls slide down the first mesh frame 321 into the recovery box 5, while the iron ore enters the storage box 4 through the first mesh frame 321 for collection, that is, the complete screening and collection of the waste steel balls and the iron ore is completed. During the whole process, the vibration motor 38 is in working state to help speed up the movement of the waste steel balls and the iron ore.
