Problems solved by technology

[0005] However, for the ore feeding of the vertical ring high gradient magnetic separator, its particle size distribution is generally wide, and the configuration of a single-diameter magnetic gathering medium can only effectively separate part of the narrow-level mineral particles, while finer-grained minerals The separation effect of particles is poor, so the use of a single-diameter magnetic-gathering medium will result in higher tailings grades when separating weakly magnetic iron ores with uneven particle size distribution

Embodiment 1

[0023] For the weak magnetic hematite ore with a particle size of -0.074mm and a content of 50%-60%, the multi-gradient conversion structure in the present invention is used for sorting, and the magnetic gathering medium rod 2-1 with a diameter of 2mm and a diameter of The 3mm magnetic gathering medium rods 2-2 are arranged alternately along the circumferential direction of the conversion, and the gap between the magnetic gathering medium sticks is 3mm. On the one hand, because the filling rate of the magnetic-gathering medium is 12% higher than that of the traditional conversion structure, the processing capacity per unit time is increased by 10.5% when the equipment model remains unchanged. On the other hand, due to the use of two kinds of magnetic gathering media with different diameters, compared with the traditional single magnetic gathering medium rod (only using a magnetic gathering medium with a diameter of 3mm), the fine particles with a particle size of ≤0.1mm in each...

Embodiment 2

[0025] For the fine-grained weak magnetic hematite ore with a particle size of -0.074mm and a content of 80%-90%, the multi-gradient conversion structure in the present invention is used for sorting, and the magnetic gathering medium rods with a diameter of 1.5mm are used for 2- 1 and magnetic gathering medium rods 2-2 with a diameter of 2 mm are arranged alternately along the circumferential direction of the conversion, and the gap between the magnetic gathering medium rods is 2 mm. On the one hand, because the filling rate of the magnetic-gathering medium is 14.5% higher than that of the traditional conversion structure, the processing capacity per unit time is increased by 11.9% when the equipment model remains unchanged. On the other hand, due to the use of two kinds of magnetic gathering medium rods with different diameters, compared with the traditional single magnetic gathering medium rod (only using a magnetic gathering medium with a diameter of 2mm), the fine particle ...

Abstract

The invention discloses a vertical ring multi-gradient magnetic separator rotary ring structure. The vertical ring multi-gradient magnetic separator rotary ring structure comprises a central disc, a side ring plate, magnetism gathering medium boxes and magnetism gathering media; the rotary ring structure is characterized in that the periphery of the central disc and the side ring plate are correspondingly and isometrically provided with bolt holes, the magnetism gathering medium boxes are fixedly connected with the central disc and the side ring plate through bolts, the magnetism gathering media have the different diameters, and the magnetism gathering medium boxes are alternately arranged in the rotary ring magnesium gathering medium structure according to the difference of the diametersof the magnetism gathering media. The sizes of the magnetism gathering medium rods with the different diameters are 1-4mm. The rotary ring structure has the advantages that (1) the filling rate of themagnetism gathering media is improved, and the treatment capability is increased by 10% or above; and (2) the magnetism gathering media boxes with the diameters of the magnetism gathering media beingdifferent are alternately mounted, recycling of fine-sized weakly magnetic minerals is achieved, and the tailings grade is reduced by 0.5% or above.

Description

technical field [0001] The invention belongs to the technical field of vertical-ring high-gradient magnetic separators for magnetic separation equipment, and in particular relates to a rotary ring structure for vertical-ring multi-gradient magnetic separators. Background technique [0002] The vertical ring high-gradient magnetic separator is one of the key equipments for the separation of weak magnetic minerals and the removal and purification of non-metallic ores. Magnetic field, and then use the magnetic gathering medium at this position to generate a higher induction magnetic field to achieve the separation of weakly magnetic minerals and non-magnetic minerals. The magnetic gathering medium box is fixed on the rotating ring of the vertical ring high gradient magnetic separator made of non-magnetic stainless steel material. When working, the rotating ring rotates clockwise. Rotary ring, the magnetic gathering medium on the rotating ring is magnetized in the magnetic fiel...
