Description

Technical Field

[0001] The embodiments of the present application relate to the field of crushing-magnetic separation technology in mineral processing plants, and in particular to a rail-mounted sorting system and a method of use. Background Art

[0002] Currently, there are numerous open-pit magnetite mines in places like Africa, Brazil, and Australia. A significant portion of these magnetite mines produces ore with an iron grade between 40% and 50%. These open-pit magnetite mines typically require dry separation to remove the gangue and surrounding rock present in the ore, bringing the grade to between 58% and 62% for sale.

[0003] However, magnetite with a grade between 40% and 50% is generally dry-selected directly after coarse or medium crushing. Since the products of coarse and medium crushing are large in size, many large pieces of ore are a mixture of ore and gangue. If this part of the ore enters the waste rock, it will reduce the recovery rate of the final concentrate, and if it enters the ore, it will reduce the grade of the nearest concentrate.

[0004] At the same time, the existing crushing device and dry sorting device are fixedly installed near the mining site. After the mining is completed, the crushing device and dry sorting device are large in size, difficult to disassemble, and difficult to recycle. The only options are to consume a lot of manpower for recycling or directly discard them, which increases production costs. Summary of the Invention

[0085] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0086] like Figure 1-2 As shown, according to the first aspect of the embodiment of the present application, a rail-mounted sorting system is provided, including a rail-mounted transport device 100; a medium crushing and coarse selection module 200, which is arranged on the rail-mounted transport device 100; a fine crushing and selection module 300, which is arranged on the rail-mounted transport device 100; a vehicle-mounted module 400, which has two groups, one for movably connecting the medium crushing and coarse selection module 200 to the rail-mounted transport device 100, and the other for rotatably connecting the fine crushing and selection module 300 to the rail-mounted transport device 100; a transfer module 500, which is used to transfer materials sorted by the medium crushing and coarse selection module 200 and the fine crushing and selection module 300.

[0087] The rail-mounted sorting system provided in the embodiment of the present application includes a rail-mounted transport device 100, a vehicle-mounted module 400, a medium crushing and roughing module 200, and a fine crushing and selecting module 300. The medium crushing and roughing module 200 and the fine crushing and selecting module 300 are arranged on the rail-mounted transport device 100 through the vehicle-mounted module 400, and a transfer module 500 is used for transferring the materials sorted by the medium crushing and roughing module 200 and the fine crushing and selecting module 300. The present invention integrates the medium crushing and roughing module 200 and the fine crushing and selecting module 300 on the rail-mounted transport device 100. When the system is put into use, the medium crushing and roughing module 200 and the fine crushing and selecting module 300 are adjusted to a vertical position through the vehicle-mounted module 400, and the material first enters the medium crushing and roughing module 200 and the fine crushing and selecting module 300. 00 for medium crushing and roughing, then the separated coarse magnetite is put into the fine crushing and selecting module 300 through the transfer module 500, and finally the fine magnetite separated by the fine crushing and selecting module 300 is put into the recovery device through the transfer module 500. When the entire system needs to be transferred, the medium crushing and roughing module 200 and the fine crushing and selecting module 300 are adjusted to a horizontal position through the vehicle-mounted module 400 and fixed on the rail-mounted transport device 100, and finally transferred through the rail-mounted transport device 100. The system of the present invention integrates medium crushing and roughing into an all-in-one machine, and fine crushing and selecting into an all-in-one machine, thereby realizing a high degree of integration of medium crushing-roughing-fine crushing-selection modules, and finally reducing the particle size of the product to about 10 mm after fine crushing, greatly increasing the dissociation of ore and gangue, Thus, high-quality iron ore with high grade and recovery rate is obtained, with low cost and high benefit. At the same time, the present invention integrates the equipment of the secondary crushing-roughing-fine crushing-concentrating module process and sets it on a train, so there is no need to set up various crushing workshops and dry separation workshops contained in traditional fixed plant buildings, which reduces capital investment. All equipment of the secondary crushing-roughing-fine crushing-concentrating module process of the present invention are integrated into the rail-mounted transportation device, thereby realizing the full mobility of the entire ore processing facility, so that the entire processing facility can be quickly moved as the mining area changes, greatly reducing the transportation cost of the raw ore and reducing production costs.

[0088] like Figure 1-2 As shown, the vehicle-mounted module 400 includes: a platform 410, which is fixedly connected to the rail-mounted transport device 100; a telescopic part 420, the end of which is rotatably connected to the platform 410, and the head end of which is rotatably connected to the middle of the medium crushing and coarse selection module 200 or the fine crushing and selection module 300.

[0089] In this technical solution, when the system is put into use, the telescopic part 420 is extended, the shapes of the medium crushing and roughing module 200 and the fine crushing and selection module 300 are adjusted to vertical, and the bottom ends are fixed to the production site. When the system needs to be moved, the telescopic part 420 is retracted, and the medium crushing and roughing module 200 and the fine crushing and selection module 300 are adjusted to horizontal, and fixed to the platform 410 through the telescopic part 420, so that they can be moved as a whole through the rail-mounted transport device 100. The present invention realizes the fixation and rotation of the medium crushing and roughing module 200 and the fine crushing and selection module 300 through the vehicle-mounted module 400. When ore dissociation is carried out, the telescopic part 420 can be used as a support rod to fix the dissociation module. When the dissociation module is fixed on the rail-mounted transport device 100, the telescopic part 420 can be used as a fixing device to fix the dissociation module.

[0090] like Figure 1-2 As shown, the vehicle-mounted module 400 includes: a first hinge part 430, which connects the platform 410 and the end of the telescopic part 420; a second hinge part 440, which connects the head end of the telescopic part 420 and the medium crushing and coarse selection module 200 or the fine crushing and selection module 300; and a third hinge part 450, which connects the end of the platform 410 and the medium crushing and coarse selection module 200 or the fine crushing and selection module 300.

[0091] In this technical solution, the telescopic part 420 is connected to the platform 410 and the medium crushing and coarse selection module 200 and the fine crushing and selection module 300 using a hinged part, which makes the connection angle more flexible and facilitates the state adjustment of the medium crushing and coarse selection module 200 and the fine crushing and selection module 300.

[0092] It is understandable that all hinged parts can be locked. When the system status is adjusted, the hinged parts are locked to reduce shaking during production or movement.

[0093] like Figure 1-2 As shown, the transfer module 500 includes: a lifting part 510, which is arranged at the head end of the platform 410; a stone conveying part 520, which adopts a belt conveying assembly, and the stone conveying part 520 is detachably connected to the platform 410, and the head end of the stone conveying part 520 is arranged below the discharge port of the medium crushing and coarse selection module 200 or the fine crushing and selection module 300; a hopper 530, which is arranged on the lifting part 510 in a liftable manner, and when the hopper 530 is at the bottom, it is lower than the end of the stone conveying part 520, and when the hopper 530 is at the top, it is higher than the fine crushing and selection module 300 or the recovery device.

[0094] In this technical solution, the transfer module 500 includes a lifting part 510, a material conveying part 520, and a hopper 530, wherein the material conveying part 520 is arranged on the platform 410, and the first section of the material conveying part 520 is arranged below the discharge port of the medium crushing and coarse selection module 200 or the fine crushing and selection module 300, and the end of the material conveying part 520 is close to the lifting part 510. During the production process, the separated magnets fall onto the material conveying part 520 and are transferred to the lifting part 510 through the material conveying part 520 and enter the hopper 530. Then the lifting part 510 lifts the hopper 530, and finally the material in the hopper 530 is put into the next-level dissociation and sorting device or the recovery car. The system of the present invention feeds the product into the concentrate conveying train and the recovery car through the lifting part 510, thereby eliminating the concentrate belt conveying and storage facilities, and reducing investment and operating costs.

[0095] like Figure 1-2 As shown, the transfer module 500 also includes: bolt connectors 540, which are arranged at intervals, and the bolt connectors 540 bolt-connect the material conveying part 520 and the platform 410; a first hanging part 550, which is arranged at intervals along the lower edge of the side surface of the material conveying part 520; and a second hanging part 560, which is arranged at intervals along the side surface of the platform 410 and corresponds to the first hanging part 550.

[0096] In this technical solution, the stone conveying part 520 is detachably connected to the platform 410 by a bolt connector 540, and a first hanging part 550 and a second hanging part 560 are provided on the side surface of the stone conveying part 520 and the platform 410. When production is in progress, the stone conveying part 520 is fixed to the platform 410 by bolts, and when moving, the stone conveying part 520 is fixed to the side of the platform 410 by the first hanging part 550 and the second hanging part 560. In this way, the positions of the stone conveying part 520 and the crushing and sorting module are non-overlapping in the transportation state and the working state, thereby creating conditions for integrating all facilities into one train.

[0097] like Figure 1-4 As shown, the transfer module 500 also includes: a waste rock longitudinal conveying part 570, which is arranged below the waste trough of the medium crushing and roughing module 200 and the fine crushing and selection module 300; and a waste rock transverse conveying part 580, which is connected to the end of the waste rock longitudinal conveying part 570.

[0098] In this technical solution, the waste rock longitudinal conveying part 570 is arranged below the waste trough of the medium crushing and roughing module 200 and the fine crushing and selection module 300, and the waste rock transverse conveying part 580 is connected to the end of the waste rock longitudinal conveying part 570. In order to avoid conflict, the waste rock transverse conveying part 580 is arranged below the material rock conveyor. The waste rock may be dispersed during the falling process and cannot fall into the waste rock transverse conveying part 580. Therefore, the waste rock longitudinal conveying part 570 is added to convey the material rock longitudinally to the waste rock transverse conveying part 580, thereby realizing the recovery and transportation of the waste rock. There is no need to manually clean the waste rock accumulated below the medium crushing and roughing module 200 and the fine crushing and selection module 300, thereby increasing the integration of the system.

[0099] like Figure 3-6 As shown, the medium crushing and roughing module 200 includes: a first frame 210, which is rotatably connected to the rail-mounted transport device 100 through the on-board module 400; a medium crushing assembly 220, which is arranged on the first frame 210; a roughing assembly 230, which is arranged on the first frame 210 and below the medium crushing assembly 220; the roughing assembly 230 includes a first annular cavity 231, which is an annular cavity surrounded by an inner annular surface and an outer annular surface, with a small upper opening and a large lower opening, and a generatrix inclination angle of the first annular cavity 231 is 75° to 85°; a second annular cavity 232, which is an annular cavity surrounded by an inner annular surface and an outer annular surface, with a large upper opening and a small lower opening, and a generatrix inclination angle of the second annular cavity 232 is 75° to 85°; the lower surface of the first annular cavity 231 It is docked with the upper surface of the second annular cavity 232; the first magnetic system 233, the first magnetic system 233 is arranged inside the inner ring surface of the first annular cavity 231, and the first magnetic system 233 adopts a fan-shaped magnetic system with an angle of 270° to 300°; the first driving member 234, the output end of the first driving member 234 is connected to the inner ring surface of the first annular cavity 231, and is used to rotate the inner ring surface of the first annular cavity 231; the first discharge hopper 235, the first discharge hopper 235 is arranged below the second annular cavity 232, the first discharge hopper 235 is a fan-shaped groove, and the position of the first discharge hopper 235 corresponds to the first magnetic system 233; the second discharge hopper 236, the second discharge hopper 236 is arranged below the second annular cavity 232, the second discharge hopper 236 is a fan-shaped groove, and the position of the second discharge hopper 236 corresponds to the notch of the first magnetic system 233.

[0100] In this technical solution, the secondary crushing component 220 and the roughing component 230 are both arranged on the first frame 210, and an integrated arrangement is achieved through the first frame 210. During the production process, the material stone is put into the secondary crushing device for secondary crushing. The material stone after secondary crushing enters the first annular cavity 231 in the roughing component 230. The design of the first annular cavity 231 with a narrow upper mouth and a wide lower mouth allows the material stone to contact the inner ring surface of the first annular cavity 231 as much as possible. The first magnetic system 233 arranged inside the inner ring surface attracts the magnet, and the waste stone enters the first row hopper 235. At the same time, the first driving member 234 drives the inner ring surface to rotate, and the magnet attracted to the inner ring surface rotates with the inner ring surface to the gap of the first magnetic system 233. The magnet loses attraction and falls into the second row hopper 236.

[0101] It is understandable that the field strength of the outer surface of the first magnetic system 233 is 400-600 mT, and the inner surface of the first annular cavity 231 can be provided with a plurality of strip plates along the axial direction to drive the magnets adsorbed thereon to rotate.

[0102] The first magnetic system 233 of the rough selection device of the present invention is an annular structure with a large magnetic selection area, which is conducive to ensuring a high recovery rate of magnetic iron. The circumferential angle of the cross-section of the magnetic separator is 270°-300°, so that most of the circumference is used for magnetic separation, ensuring the separation effect. The remaining 60° non-magnetic selection area uses the feed raw materials and the dry-selected ore as ore products. Such a structure avoids the loss of magnetic minerals in the feed raw materials in the non-magnetic selection area, thereby ensuring the recovery rate of magnetic iron of magnetite and laying the foundation for high returns. The first magnetic system 233 of the present invention is built into the inner ring surface. The first magnetic system 233 does not directly contact the large-block products of the medium crushing, effectively avoiding the large-block ore from hitting the surface of the annular magnetic separator and protecting the annular magnetic separator.

[0103] like Figure 3-6As shown, the crushing and selecting module 300 includes: a second frame 310, which is rotatably connected to the rail-mounted transport device 100 through the vehicle-mounted module 400; a crushing assembly 320, which is arranged on the second frame 310; a selecting assembly 330, which is arranged on the second frame 310 and below the crushing assembly 320; the selecting assembly 330 includes a third annular cavity 331, which is an annular cavity surrounded by an inner annular surface and an outer annular surface, with a small upper opening and a large lower opening, and a generatrix inclination angle of the third annular cavity 331 is 75° to 85° ; The fourth annular cavity 332 is an annular cavity enclosed by an inner annular surface and an outer annular surface, with a larger upper opening and a smaller lower opening. The generatrix inclination angle of the fourth annular cavity 332 is 75° to 85°; the lower surface of the third annular cavity 331 is connected to the upper surface of the fourth annular cavity 332; the second magnetic system 333 is arranged inside the cavity enclosed by the inner annular surface of the third annular cavity 331; the second magnetic system 333 includes a circular top plate, which is arranged on the top of the cavity enclosed by the inner annular surface of the third annular cavity 331; the circular bottom plate, which is arranged in the third annular cavity 331 The bottom of the cavity surrounded by the inner annular surface; a rotating shaft, the rotating shaft is arranged between the circular top plate and the circular bottom plate; a first electromagnetic pole 3331, the first electromagnetic pole 3331 is arranged inside the cavity surrounded by the inner annular surface of the third annular cavity 331; a plurality of second electromagnetic poles 3332, the second electromagnetic poles 3332 are arranged at intervals along the axial direction of the rotating shaft; a power ring 3333, the power ring 3333 is arranged on the circular bottom plate, and the wrap angle of the power ring 3333 is 270° to 300°; a contact 3334, the contact 3334 is arranged at the bottom of each second electromagnetic pole 3332, and the position of the contact 3334 Corresponding to the position of the power-connecting ring 3333; the selecting component 330 also includes a second driving member 334, and the output end of the second driving member 334 is connected to the rotating shaft; a third row of hoppers 335, the third row of hoppers 335 is arranged below the fourth annular cavity 332, the third row of hoppers 335 is a fan-shaped groove, and the third row of hoppers 335 corresponds to the position of the power-connecting ring 3333; a fourth row of hoppers 336, the fourth row of hoppers 336 is arranged below the fourth annular cavity 332, the fourth row of hoppers 336 is a fan-shaped groove, and the fourth row of hoppers 336 corresponds to the position of the notch of the power-connecting ring 3333.

[0104] In this technical solution, the selected magnets of the material entering the fine crushing and selection module 300 are crushed by the fine crushing component 320, and then the finely crushed material enters the selection component 330. In the selection component 330, the electromagnetic system composed of the first electromagnetic pole 3331, the second electromagnetic pole 3332 and the power ring 3333 attracts the selected material, and causes the waste stone to flow into the third row hopper 335. The attracted finely crushed material is lighter in weight and can move with the movement of the second electromagnetic pole 3332, and finally moves to the position of the gap in the power ring 3333. The second electromagnetic pole 3332 of the magnet is powered off, losing the attraction to the finely crushed magnets, and the finely crushed magnets enter the fourth row hopper 336 and are recycled.

[0105] It can be understood that the first electromagnetic pole 3331 of the present invention can adjust the field strength between 300-500mT by controlling the size of the connected current, thereby realizing the control and adjustment of the magnetic adsorption of the ore; the variable frequency speed regulation of the rotating motor of the magnetic separator realizes the adjustment of the sorting time of the ore in the sorting area, which can realize the control and adjustment of the sorting time, thereby realizing the adjustment and control of the sorting magnetic force and sorting time, and ensuring the acquisition of high-index sorted ore products.

[0106] The beneficiation component 330 uses a relatively low field strength to eject the finely crushed and dissociated gangue and the ore-gangue conjoined bodies with low magnetic iron content to ensure the grade of the final product.

[0107] like Figure 3 and 4 As shown, the rail-mounted sorting system further includes ground anchors 600 . Four ground anchors 600 are respectively provided at the bottom of the first rack 210 and the second rack 310 . The anchor rods of the ground anchors 600 are fully threaded structures.

[0108] When the medium crushing and roughing module 200 and the fine crushing and selecting module 300 of the present invention are in operation, they are placed on the foundation through the four circular ground anchors 600 at their respective bottoms. The vehicle body is not subjected to force during operation, which protects the vehicle body safety and improves the stability of the medium crushing and roughing module 200 and the fine crushing and selecting module 300 during operation.

[0109] like Figure 7 As shown, according to a first aspect of an embodiment of the present application, a method of use is provided, which is applied to any of the above-mentioned rail-mounted sorting systems, comprising:

[0110] Step 101: Using the vehicle-mounted module, adjust the medium crushing and roughing module and the fine crushing and cleaning module to a vertical position and put them into working state;
