[0021] Specifically, after the fine particles of mud and sand fall onto the roller body 302, the motor 310 is started, and the motor 310 drives the wheel 307 to rotate, so that the wheel 307 drives the transmission roller 308 to rotate through the belt 309, so that the gear 304 drives the blade 303 on the roller body 302 to crush the mud and sand clumps and particles, and the crushed mud and sand enter the collecting bucket 311 to be collected and flow into the conical groove 314 on the upper grinding mill 312, and the motor 320 is started, and the motor 320 drives the lower grinding mill 317 to rotate, and the mud and sand enter the gathering groove 316 through the drop port 315 for accumulation, and gradually as the lower grinding mill 317 rotates, it is brought into the gap between the lower grinding mill 317 and the upper grinding mill 312 for grinding, so as to further grind and refine the particles, and the ground and refined mud and sand particles will fall from the inclined edge on the upper side of the lower grinding mill 317.

[0024] Specifically, when the dryness of fine-grained mud and sand in the iron tailings transported into the device is high, in order to reduce the dust generated by crushing, the water pump 405 is started, and the water pump 405 transports the water stored in the water tank 401 into the manifold 403 through the diversion pipe 402. When flowing out from the nozzle 404, the water pressure is increased through the small water outlet holes of the nozzle 404, so that the water flow is transformed into water mist and sprayed out at a high speed, which moistens the fine-grained mud and sand in the iron tailings to be crushed, thereby reducing dust.

[0026] Reference Figure 7 and Figure 8 In a preferred embodiment, the vibration screening module 5 includes a bearing frame 501, the outside of the bearing frame 501 is connected to the inner wall of the box body 1 by bolts, a guide bucket 502 is arranged above the bearing frame 501, the outside of the guide bucket 502 is connected to the inner wall of the box body 1 by bolts, the guide bucket 502 is located below the support frame 319, and the box body 1 is provided with a rectangular frame 1 505 and a rectangular frame 2 506 on both sides away from the bearing frame 501; the inner wall of the bearing frame 501 is rotatably connected to the screening frame 503 through a bearing, the inner wall of the screening frame 503 is connected to the filter screen 509 by bolts, the filter screen 509 is located below the guide bucket 502, and the rectangular frame 2 The inner wall of 506 is connected to an upper guide plate 507 by bolts, and the outer part of the upper guide plate 507 contacts with the end of the screening frame 503 away from the rectangular frame 505, and the inner wall of the rectangular frame 505 is connected to a lower guide plate 508 by bolts, and the lower guide plate 508 is located below the screening frame 503; the same circular opening is opened on the same side of the supporting frame 501 and the box body 1, and the same short shaft is rotatably connected in the circular opening through a bearing, and the side of the short shaft close to the screening frame 503 is connected to an eccentric piece 510 by bolts, and the outer part of the box body 1 is connected to the motor 2 504 by bolts, and the output end of the motor 2 504 is connected to the side of the short shaft away from the eccentric piece 510 through a coupling.
[0027] Specifically, the ground sand particles are guided by the guide bucket 502 and fall to a higher position of the screening frame 503, and the motor 504 is started. The motor 504 drives the eccentric member 510 to rotate, so that the eccentric member 510 can use the irregular position to lift the screening frame 503 during rotation, and then rotate away from the irregular position of the eccentric member 510 and fall down, so that the screening frame 503 generates a pulsation, so that the filter screen 509 can remove the sand on it by the influence of the pulsation. The sand particles are filtered, and the particles with larger particle sizes that do not meet the requirements roll down along the inclined surface of the screening frame 503 and accumulate at the junction of the upper guide plate 507 and the screening frame 503. When the screening frame 503 is lifted by the eccentric piece 510 for the next time, the particles are pushed onto the upper guide plate 507 and discharged out of the box body 1. The particles passing through the filter holes of the filter screen 509 will fall onto the lower guide plate 508, and then roll down along the inclined surface of the lower guide plate 508 to the outside of the box body 1 and be collected.
[0028] In specific application scenarios, the vibration screening module 5 is mainly suitable for the dynamic screening link in the dynamic screening process, that is, the vibration screening module 5 uses the eccentric piece 510 and the screening frame 503 to enable the device to quickly filter the sediment particles that fall onto the filter screen 509. By using vibration, it avoids excessive accumulation of large sediment particles on the filter screen 509, causing clogging of the filter holes and affecting the device's filtering of fine sediment particles, thereby improving the efficiency of the device in screening sediment particles.
[0029] Working principle: After the fine particles of mud and sand in the iron tailings are transported to the box body 1 through the feed hopper 2, in the process of the fine particles of mud and sand falling, if the mud and sand are too dry, in order to reduce the dust generated by crushing, the water pump 405 is started, and the water pump 405 transports the water stored in the water tank 401 into the manifold 403 through the diverter pipe 402. When the water flows out from the nozzle 404, the water pressure is increased through the small water outlet holes of the nozzle 404, so that the water flow is turned into water mist and sprayed out at a high speed, which moistens the fine particles of mud and sand in the iron tailings to be crushed, thereby reducing dust. When the fine particles of mud and sand fall to the roller After the upper grinding mill 312 is mounted on the upper grinding mill 314, the motor 320 is started, and the motor 320 drives the rotating wheel 307 to rotate, so that the rotating wheel 307 drives the transmission roller 308 to rotate through the belt 309, so that the gear 304 drives the blade 303 on the roller body 302 to crush the silt lumps and particles, and the crushed silt enters the collecting bucket 311 to collect and flow into the conical groove 314 on the upper grinding mill 312, and the motor 320 is started, and the motor 320 drives the lower grinding mill 317 to rotate, and the silt enters the gathering groove 316 through the lower drop port 315 to accumulate, and gradually flows along with the lower grinding mill 312. The particles are further ground and refined, and the ground and refined sediment particles fall from the upper inclined edge of the lower grinding mill 317. The ground sediment particles fall to a higher position of the screening frame 503 under the guidance of the guide bucket 502, and the motor 504 is started. The motor 504 drives the eccentric piece 510 to rotate, so that the eccentric piece 510 can use the irregular position to lift the screening frame 503 and rotate away from the irregular position of the eccentric piece 510. The particles passing through the filter holes of the filter screen 509 will fall onto the lower guide plate 508, and then roll down along the inclined surface of the lower guide plate 508 to the outside of the box 1 and be collected.
