Problems solved by technology

[0002] Conventional magnetite and hematite separation processes generally go through weak magnetic separation and strong magnetic separation, that is, the strong magnetic mineral magnetite is first selected, and then the weak magnetic iron minerals are separated. The finer magnetite is easy to cause over-grinding of hematite during the magnetite separation process, thus increasing the difficulty of separation in the subsequent process

Embodiment 1

[0031] Embodiment one: see Figure 1-Figure 4 , a vibrating screen system for iron mineral liquid magnetization separation, comprising a fixed frame 101 of the screen system, and an array of sieve units 102 disposed in the fixed frame 101 of the sieve system in a horizontally inclined stacked arrangement, and the sieve unit 102 includes The sieve plate 103, a plurality of splay-shaped medium ore diversion protrusions 104 and screens 106 vertically arranged on one side of the sieve plate 103, and the screen 106 is pressed and set on the sieve plate 105 The outer end of the medium ore guide protrusion 104 is fixed by screws. The outer end of the medium ore guide protrusion 105 intersects with the outer edge of the sieve plate 103, and the other of the sieve plate 103 corresponding to the screen 106 The two longitudinal sides of the side are provided with longitudinal ribs 107, and the longitudinal ribs 107 of the two adjacent sieve units 102 are matched and engaged with the groo...

Embodiment 2

[0035] Embodiment two: see Figure 1-Figure 9, a liquid magnetization sorting device using the vibrating screen system described in Embodiment 1, comprising a support frame 2, a vibrating screen system 1 matched and placed in the support frame 2, and a vibrating screen fixed on the support frame 2 and correspondingly arranged It is a magnetized magnetic system on both sides. The support frame 2 is a cylindrical structure with an open top and sealed bottom and sides. The bottom section of the support frame 2 gradually shrinks. The top of the support frame 2 is equipped with a 1 corresponding to the feeding mechanism, the lower part of the support frame 2 is provided with a concentrate bin and a middle ore bin corresponding to the vibrating screen system 1, and the bottom of the concentrate bin and the middle ore bin are respectively provided with a concentrate discharge port 202 and a middle ore discharge In port 201, the magnetization magnetic system includes two planar magnet...

Embodiment 3

[0038] Embodiment three: see Figure 1-Figure 6 , Figure 10 , Figure 11 , the structure of this embodiment is basically the same as that of Embodiment 2, and the similarities will not be repeated. The difference is that: the support frame is provided with a plurality of sorting units of the vibrating screen system 1, and the mutual The sorting units are independent of each other, and the lower and upper parts of each sorting unit are equipped with concentrate bins, medium ore bins and feeding mechanisms that match the vibrating screen system, thereby increasing the sorting efficiency.

Abstract

The invention belongs to the technical field of iron ore upgrading. A vibrating screen system, sorting device and method for liquid-state magnetization sorting of iron minerals, using fine-grained magnetite with a low content as a carrier, and magnetizing weakly magnetic iron minerals to form agglomerated iron minerals through an applied uniform strong magnetic field The aggregates slide down along the surface of the inclined vibrating screen in a liquid environment, and the gangue minerals pass through the screen under the vibration of the screen body and its own gravity, so as to avoid over-grinding of iron minerals, reduce inclusions in conventional strong magnetic separation processes, and improve precision. Mineral quality, to achieve selective separation of iron minerals and gangue minerals.

Description
