Description
Technical field
The magnetic that thick, subparticle composition is classified on the same stage, fluidization is sorted in strongly magnetic mineral is directed to the present invention relates to a kind of
Screening device, designs different magnetic system structures correspondence size fractionated materials and is sorted, suction type of the dependent of dead military hero in mining machinery, weak magnetic
Choose to install standby category.It has certain application value in micro-size fraction Iron ore industry sorting field.
Background technology
At present, the strongly magnetic mineral such as iron ore is in ore dressing process, to improve the grade of concentrate iron, typically using ore grinding-dry
Iron-bearing mineral component degree of dissociation is improved in method magnetic separation process flow, the flow, and the lifting of efficiency of magnetic separation is beneficial in theory.
But the problem of occurring in that larger simultaneously：Overground phenomenon formation micro-size fraction Magnetic Materials inevitably occur in grinding process
Material, because the meticulous probability with coarse granule magnetic component formation magnetic linkage of granularity reduces（The probability being carried over concentrate reduces）, and by
Act on and increasing to other non magnetic ore component drag forces, add sorting mode and the backwardness of sorting process, cause the part magnetic
Material is not sorted effectively and lost in mine tailing, and material is wasted significantly.
At present, it is contemplated that the reluctant state of the art of microfine iron ore, Most scholars devise relatively advanced, applicable
Stronger classification-magnetic separation the handling process of property.Patent " CN201510237394.7 " carries out dry type magnetic separation for 3mm particulates iron ore,
Magnetic separation rough concentrate delivers to the classification of wind-force powder concentrator, the further dry type magnetic separation of micro-size fraction iron ore after classification.Patent
" CN201510121314.1 " is disclosed to improve specularite concentrate quality method, first carries out coarse fraction wet classification, overflow particulate
Product obtains selected and mine tailing by low intensity magnetic separation, and mine tailing obtains final concentrate product by gravity treatment, high intensity magnetic separation；Patent
" CN201010532677.1 " is disclosed to be directed to quartz sand processing method, by Separation by vibration, washing separation, vibration separation final election
Three classifications, obtain thick fine particle stage material and handle respectively, it is to avoid crushing, product granularity are uniform excessively.Above-mentioned patent is concern
The importance of micro-size fraction material special disposal, but the sorting equipment used（Especially dry-type magnetic extractor）, it is mostly routine
Type, the microfine iron ore efficiency of separation is not high.
Further consider conventional magnetic separator processing micro-size fraction Iron Ore Powder it is easy bond, sort not thoroughly, concentrate loss asks
Topic, designs fluidization sorting unit.Disclosed patent " CN201310124774.0 " is a kind of annular magnetic separation space, magnetic system structure
Magnetic pole and filling medium are closed to pole formula including provide background magnetic field intensity, and magnetic concentrate is by sticking to dielectric surface
Periodically taken out of magnetic separation space to be collected, easily blocked.Patent " CN201420279812.X ", for micro fine particle magnetite
Fluidization dry type magnetic agglomeration gravity separation equipment is designed, by magnetic component in magnetic field space formation magnetic coagulation, by wind-force, gravity and magnetic
Power collective effect, moves to the discharge of Magnetic Materials material receiving port obliquely, but micro-size fraction magnetic component material is from windage
Under magnetic coagulation phenomenon it is weaker, therefore separating effect can be influenceed.
The content of the invention
The purpose of the present invention exactly provides a kind of ferromagnetism ore deposit for the weak point in the presence of above-mentioned prior art
Thing is classified fluidization weak magnetic screening device.The device is a kind of classification for coarse fraction and micro-size fraction and the stream sorted on the same stage
State concentration equipment, can reduce the triviality for handling fine iron ore technique, and enhancing magnetic separation specific aim, high-grade and height can be achieved
Rate of recovery magnetic concentrate.Furtherly, the device can realize that fluidized classifying is sorted iron ore on the same stage, particularly with micro-size fraction iron
Ore deposit specific aim provides the magnetic system structure design that magnetic upset can be achieved, and the final starting point is the high-quality recovery of microfine iron ore.
