Background technique

The main characteristics of my country's iron ore are "poor", "fine" and "miscellaneous", and the iron grade is 32%-37%, which is about 10 percentage points lower than the world average. Among them, 97% of the iron ore needs beneficiation treatment. Magnetite ore beneficiation has always been the main body of iron ore beneficiation. In my country's iron ore concentrate production, magnetite concentrate is mainly. Mineral beneficiation is based on the physical and chemical properties of different minerals in the ore, after the ore is crushed and ground, gravity separation, flotation, magnetic separation, electric separation, etc. are used to separate useful minerals from gangue minerals, and make each The process of separating the symbiotic or associated useful minerals from each other as much as possible to remove or reduce harmful impurities to obtain raw materials for smelting or other industries. Mineral beneficiation equipment is the main tool used in the beneficiation process. The current beneficiation equipment still has the following problems: First, the crushing process after ore mining is not thorough enough, and it is easy to cause the subsequent processing machine to jam or even be damaged in the subsequent beneficiation process because the ore particles are too large or the hardness is too large. Not only will it affect the mineral processing cycle, but it will also cause great hidden dangers to production safety. Second, the current concentrators can only roughly sieve minerals, and cannot accurately separate and strip high-value ores with metallic attributes from impurities without metallic attributes, which makes the subsequent processing complicated and processing efficiency low. Third, the current beneficiation equipment cannot classify and collect valuable ores according to their size and particle size. In summary, the design and development of a mineral processing equipment has become an urgently needed topic. In summary, in view of the above problems, the design and development of a multi-functional mineral processing equipment has become an urgent need.

When the present invention is used: the mineral raw materials are poured into the crushing cavity 3 of the primary crushing system through the feeding hopper 2, and the blocking plate 201 plays the role of buffering the falling of the minerals, thereby controlling the speed of the feeding. The minerals are sheared and crushed in the crushing chamber 3 by the high-speed convection and strong wind sent by the air supply pipes 4 on both sides of the lower end, and the minerals that are blown by the strong wind and rolled at high speed hit the crushing knife 301 and the continuously rotating crushing roller 302. When crushed, the minerals reduced by the crushed particles enter the inner ring 304 through the opening at the connection between the inner ring 304 and the collecting plate 305 and then fall into the crushing pipe 5 . The control frame 303 can control the crushing roller 302 to rotate. Compressor fan 1 4012 provides strong wind and is fed into the air storage tank 407 by the first pipe 4011 through the filter hole 4010. The strong air in the air storage tank 407 is passed into the two air supply ducts 4, and the strong wind is heated in the air supply duct 4 in turn. The rod 405 , the isolation plate 404 , the secondary air plate 402 and the primary air plate 401 are sent into the crushing cavity 3 . The heater 406 can control the heating rod 405 to heat the strong wind so as to achieve the purpose of drying the minerals with the hot wind. The isolation plate 404 and the filter hole 4010 can play the role of preventing the backflow of minerals. The controller 403 can control the opening and closing size of the primary air plate 401 and the secondary air plate 402 so as to control the wind speed entering the crushing chamber 3 . air volume. The minerals that have been crushed and dried in the first stage enter the crushing pipe 5 and are further crushed by the auger knife 503. After the electromagnet coil group 505 in the outer cavity 504 is energized to generate magnetism, the metal in the crushing pipe 5 can be crushed. The minerals are adsorbed on the convex balls 501 in the crushing pipe 5 , so that the minerals are effectively broken by the auger knife 503 . The first power supply box 507 can supply power to the second rotating shaft machine 502 and the first electromagnet coil group 505 through the power supply bracket 506 . The minerals that have completed the secondary crushing fall into the magnetic separation tank 6 from the lower end of the crushing pipe 5, and the metallic minerals are adsorbed on the electromagnet plate 604, and the electromagnet plate 604 is driven by the rotating shaft 605 to rotate continuously, thereby sweeping No metallic minerals in the magnetic separation tank 6 rotate from the discharge pipe 2 602 into the recovery box 1 603. When the electromagnet plate 604 rotates to the bottom of the breaking belt 608 and contacts with it, the electromagnet plate 604 is short-circuited and loses its magnetism. As a result, the metallic minerals fall from the electromagnet plate 604 and are swept into the discharge pipe 1 601 , and the metallic minerals that have completed the magnetic separation flow into the dust removal pipe 7 from the discharge pipe 1 601 . The minerals in the dust removal pipe 7 are attached to one side of the dust removal pipe 7 by the magnetic adsorption generated by the electromagnet coil group 2 706 in the box body 705 on one side, and the strong wind generated by the compressor fan 2 703 is sent into the air supply pipe network 704. When the dust removal pipe 7 blows the minerals violently, the strong wind blows the dust impurities in the minerals and the holes enter the recovery pipe 701 , and are sent to the recovery box 2 702 through the recovery pipe 701 for collection. The second power supply box 708 conducts magnetic flux to the second electromagnet coil group 706 through the conductive tube 707 . The minerals after the impurity removal are completed enter the magnetic separation tank 8 from the end of the dust removal pipe 7. The magnetic minerals generated by the electromagnet block 806 make them adsorb on the outer wall of the inner ring 2 803, and there are no metallic minerals. The material is dropped from the leak hole 801 to the recovery tank 808 for collection. The rotating machine 805 drives the electromagnet block 806. Due to the action of the magnetic force, the metallic minerals on the outer wall of the inner ring 2 803 also rotate along with it. When the metallic minerals rotate to the baffle 2 804, they can no longer be rotated and are lost. The magnetism falls into the discharge pipe 3 809 which is connected with the magnetic separation tank 8 under the baffle plate 2 804. During the falling process of the metallic minerals, it hits the cross bar 8010 in the discharge pipe 3 809 to control the falling speed. Finally, it falls into the screening tank 9, and the metallic minerals pass through a plurality of areas in which the diameters of the screening holes 902 divided by the buffer belt 901 increase in turn in the screening tank 9. The sieving holes 902 in the first area of 2000 are screened out and collected by the container, and the particles of metallic minerals are sorted and collected by the sieving holes 902 in each area from top to bottom in order from small to large. The first baffle plate 802 can prevent the non-metallic material from falling into the third discharge pipe 809, and the rotating arm 807 can control the rotation of the recovery tank 808. The strong wind generated by the compressor fan 1 4012 is passed into the magnetic separation tank 8 through the second pipe 4013, and the strong wind can further promote the minerals without metal to fall into the recovery tank 808 through the leak hole 801 for collection.
