The positioning slot 132 can limit the thinning component 14, and the limiting slot 133 can limit the crushing component 16. The temporary storage shell 131 The screening component 15 can be limited, and the temporary storage shell 131 can be driven to rotate with the transmission motor 114, so that the refining component 14 and the crushing component 16 can be driven to rotate together, so that the refining component 14 can crush the low-grade tailings, and the crushing component 16 can strike the low-grade tailings, and the screening component 15 can screen the low-grade tailings into the required size when moving, and transport the low-grade tailings to the separation component 22, and the temporary storage shell 131 can drive the grinding component 23 to move together, grind the low-grade tailings to improve the efficiency of gradient crushing.

[0051] Among them, the refinement component 14 includes a clamping frame 141, a positioning arc plate 142 and a grinding tooth 143.

The positioning arc plate 142 is limited by the clamping frame 141, and the positioning arc plate 142 can limit the grinding tooth 143, so that when the grinding tooth 143 collides with the low-grade tailings, the low-grade tailings are crushed.

[0052] Among them, the sub-screening component 15 includes a sub-screening frame 151, auxiliary teeth 152 and an intercepting rod 153.

The intercepting rod 153 is fixedly connected to the inner side of the sub-screening frame 151. By setting the sub-screening component 15, the sub-screening frame 151 can cooperate with the auxiliary teeth 152 and the intercepting rod 153, and the auxiliary teeth 152 are limited by the sub-screening frame 151.

[0054] Working principle of this embodiment: First, the external low-grade tailing iron ore conveying equipment conveys the raw materials to the positioning shell 112 through the receiving hopper 113, and the transmission motor 114 is started, which provides rotational power for the entire crushing process. The operation of the transmission motor 114 drives the temporary storage shell 131 to rotate, and the temporary storage shell 131 drives the connected refinement component 14, the crushing component 16 and the screening component 15 to move synchronously. When the low-grade tailing iron ore enters the positioning shell 112, the guide component 12 located on the inside takes the lead in playing a role, and the crushing tooth ring 121 initially crushes the incoming raw materials into smaller pieces. At the same time, the impact plate 162 in the crushing component 16 is close to the conduction block 123. Because the conduction block 123 is limited by the positioning block 122, the impact plate 162 moves along the conduction block 123 and rotates with the reset torsion spring rod 161 as the center, so that ... The angle of the striking tooth 163 changes, and then the torsion energy storage of the torsion spring rod 161 is reset. When the striking plate 162 leaves the conduction block 123, the torque is released, driving the striking plate 162 and the striking tooth 163 to strongly strike the low-grade tailings iron ore, and the struck ore quickly moves to the crushing tooth ring 121 to be further crushed. Then the temporary storage shell 131 drives the refining component 14 to rotate continuously, and the clamping frame 141 firmly positions the arc plate 142. The grinding teeth 143 on the positioning arc plate 142 continuously collide with the ore to refine the ore particles. The screening component 15 moves with the temporary storage shell 131, and the auxiliary teeth 152 are limited by the screening frame 151. The auxiliary teeth 152 crush the nearby ore, and the intercepting rod 153 intercepts larger ore fragments that do not reach the required size, so that the ore fragments that meet the specifications can pass smoothly and enter the subsequent processing process.

By rotating the separation box 221 along with the storage tray 214, the grinding round tooth 222 and the separation railing frame 223 can be driven to rotate together, so that the grinding round tooth 222 can grind the low-grade tailings between the grinding component 23, so that the low-grade tailings that have been ground can enter the separation box 221 through the separation railing frame 223 to complete the gradient crushing of the low-grade tailings into building aggregate.

[0059] Among them, the grinding component 23 includes a guide ring plate 231, a positioning ring plate 232 and a grinding round tooth 233. The guide ring plate 231 is fixedly connected to the inner side of the temporary storage shell 131, the positioning ring plate 232 is fixedly connected to the inner side of the guide ring plate 231, and the grinding round tooth 233 is fixedly connected to the inner side of the positioning ring plate 232. The inner side of the grinding round tooth 233 is close to the surface of the grinding round tooth 222. By setting the grinding component 23, the guide ring plate 231 can cooperate with the positioning ring plate 232 and the grinding round tooth 233. By rotating the guide ring plate 231 along with the rotation of the temporary storage shell 131, the positioning ring plate 232 and the grinding round tooth 233 can be driven to rotate together, so that the grinding round tooth 233 and the grinding round tooth 222 can grind the low-grade tailings iron ore.

[0060] The working principle of this embodiment is as follows: first, after the crushing mechanism 1 screens qualified crushed particles and sends them to the separation component 22, the servo motor 213 on the positioning base 211 drives the storage tray 214 to rotate, and the storage tray 214 drives the separation component 22 to rotate, and then the grinding spherical teeth 222 cooperate with the grinding spherical teeth 233 driven by the crushing mechanism 1 to grind the raw materials, and the qualified ore enters the separation box 221 through the separation railing frame 223, and then the suction pump 212 on the positioning base 211 discharges the finished aggregate that has completed the gradient crushing.
