The crushing mechanism includes a crushing box, two crushing rollers, and a mesh screening cage. The crushing box has a feed inlet connecting its interior and exterior, and a discharge outlet connecting to the inlet of the microbubble flotation machine. The two crushing rollers are arranged side by side inside the crushing box and are driven by a crushing motor. The screening cage is rotatably arranged inside the crushing box and sleeved outside the two crushing rollers, and is driven to rotate by a screening motor. The feed inlet is aligned above the two crushing rollers inside the screening cage, and multiple guide plates are distributed circumferentially on the inner wall of the screening cage. This utility model enables iron tailings to be fully crushed before entering the microbubble flotation machine, resulting in uniform particle size and ultimately screening out high-quality concentrate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-6 This utility model provides a technical solution: a fine-grained iron tailings re-concentration screening device, including a screening box 1, a discharge port 2, a fixed frame 3, an adjusting block 4, an adjusting rod 5, a first motor 6, a second motor 7, a first bevel gear 8, a second bevel gear 9, a connecting cylinder 10, a connecting rod 11, a third bevel gear 12, a fourth bevel gear 13, and a feeding roller 14.
[0029] As attached Figure 1As shown in the figure, the materials are put into the screening box 1 for screening. The concentrate is discharged into the discharge port 2 from the front side above the screening box 1, and the impurities are discharged from the lower part of the screening box 1. Specific Embodiment 1;
[0031] The existing fine-grained iron tailings re-election concentrate screening device is not convenient for discharging the screened concentrate. To solve this technical problem, in this embodiment, as shown in Appendix Figure 1 and Appendix Figure 3 and Appendix Figure 5 and Appendix Figure 6 When the second motor 7 is turned on, the second motor 7 drives the first bevel gear 8 installed at its output end to rotate. A second bevel gear 9 is meshed and connected below the first bevel gear 8. The first bevel gear 8 drives the second bevel gear 9 to rotate on the fixed frame 3 at the same time. A connecting cylinder 10 is integrally provided below the second bevel gear 9. The second bevel gear 9 drives the connecting rod 11 connected by a clamping groove in the connecting cylinder 10 to rotate. Since the cross-section of the connecting rod 11 is in the shape of a Chinese character 'zhong', the stability can be ensured. The connecting cylinder 10 drives the connecting rod 11 to rotate. A third bevel gear 12 is fixed below the connecting rod 11. The third bevel gear 12 drives the fourth bevel gear 13 meshed with it to rotate. A blanking roller 14 is fixed inside the fourth bevel gear 13. The fourth bevel gear 13 drives the blanking roller 14 to rotate. The blanking roller 14 discharges the screened concentrate above the screening box 1 into the discharge port 2. Specific Embodiment 2;

To solve this technical problem, in this embodiment, as shown in Appendix Figure 2 and Appendix Figure 3 and Appendix Figure 4 When the first motor 6 is turned on, the first motor 6 drives the adjusting rod 5 installed at its output end to rotate. The drive mechanism composed of a belt and a belt pulley drives the symmetrically distributed adjusting rods 5 at the front and back to rotate at the same time. The adjusting rod 5 drives the adjusting block 4 threadedly connected to its outside to move up and down, so that the adjusting block 4 slides in the fixed frame 3 connected to it by a clamping groove, and the height of the adjusting block 4 and the blanking roller 14 is adjusted to make the blanking roller 14 adapt to the concentrate with different densities and thicknesses.
[0034] As shown in Appendix Figure 3 and Appendix Figure 6 When the adjusting block 4 slides in the fixed frame 3, the adjusting block 4 drives the third bevel gear 12 and the fourth bevel gear 13 installed inside it to move. The connecting rod 11 fixed above the third bevel gear 12 slides in the connecting cylinder 10 connected to it by a clamping groove, which can ensure the connection stability between the connecting cylinder 10 and the connecting rod 11.
