Description
Technical field
The utility model belongs to preparation equipment field more particularly to a kind of magnetic medium, magnetic medium heap and magnetic separator.
Background technique
Weakly magnetic mineral, which produces resource, mainly bloodstone, limonite, siderite, ilmenite, wolframite, manganese ore and tantalum Biobium rare-earth
Mine etc..These weakly magnetic minerals produce raw material and have played important function in China's economic development.High-gradient magnetic separation is processing weak magnetic
The common method of mineral, but the mechanical entrainment due to being easy to produce gangue mineral in assorting room, single High-gradient Magnetic are elected to be
Industry is difficult to obtain qualified weak magnetic mineral concentrate product, and high-gradient magnetic separation is generallyd use in production and carries out roughing, gained is coarse-fine
Mine carries out the selected acquisition final concentrate product of flotation again, and process flow is complicated, and floating agent consumption is big, and production target is unstable,
And the use of floating agent is easy to produce pollution.New and effective High-gradient Magnetic choosing method is developed, High-gradient Magnetic is reduced or eliminate
The mechanical entrainment of gangue mineral during choosing utilizes the clean and effective of weak magnetic mineral and is of great significance.
Vertical ring pulsating high gradient magnetic separation equipment be it is industrial at present most widely used, although Pulsating Flow solves magnetic medium
The problem of blocking, but in assorting room gangue mineral mechanical entrainment still than more serious, and apply Pulsating Flow be unfavorable for fine fraction
The rate of recovery of the collecting of weak magnetic mineral, fine-grained minerals is lower.Studies have shown that vertical ring pulsating high gradient magnetic separation equipment sorted
Cheng Zhong, the mechanical entrainment of gangue mineral are mainly due to causing to mine stream to the direct impact of magnetic mineral accumulation region on magnetic medium
's.Magnetic mineral accumulation region is impacted to mine stream, bulky grain gangue mineral is small since the supporting role of accumulation region is trapped in accumulation region
Size gangue mineral particle enters in the gap between magnetic mineral and stays in accumulation region, forms mechanical entrainment.It improves to mine
Speed can eliminate magnetic-particle in the accumulation of medium upstream (one side of the medium in face of flow of slurry), and magnetic-particle is under medium
(backwards to one side of flow of slurry) is swum to be captured, can be to avoid mechanical entrainment, but will cause the sharply decline of the magnetic mineral rate of recovery,
And it is difficult to adjust to mine flow velocity in production, therefore cannot apply.Feasible effective method how is used to eliminate magnetic-particle in magnetic
The accumulation of medium upstream is the key that reduce or eliminate gangue mineral mechanical entrainment in high-gradient magnetic separation.
Utility model content
Technical problem to be solved in the utility model is to overcome the shortcomings of to mention in background above technology and defect, is provided
A kind of combined magnetic medium for the mechanical entrainment that can reduce gangue mineral, magnetic medium heap, intermittent magnetic plant and vertical ring are high
Gradient magnetic separator.In order to solve the above technical problems, the utility model proposes technical solution are as follows:
A kind of combined magnetic medium, the magnetic medium are in the form of a column or cyclic annular, the magnetic medium along ore pulp flow direction successively
Equipped with non-magnetic portion and magnetic-conductance portion, the non-magnetic portion is fixedly connected with each other with magnetic-conductance portion, and the edge in the non-magnetic portion is for drawing
The smooth surface structure or horn structure of stream.Magnetic-conductance portion uses permeability magnetic material, and permeability magnetic material can be engineering pure iron or ferrite
Stainless steel etc., non-magnetic portion use un-conducted magnetic material, and un-conducted magnetic material can be martensitic stain less steel etc..
In said combination formula magnetic medium, it is preferred that the cross section in the non-magnetic portion is in half diamond shape, half elliptic or semicircle
Shape, the cross section of the magnetic-conductance portion are in half diamond shape, half elliptic or semicircle.It is furthermore preferred that the cross section in the non-magnetic portion
In half diamond shape or half elliptic, the cross section of the magnetic-conductance portion is in half diamond shape or half elliptic.
In conventional vertical ring pulsating high gradient magnetic separation equipment assorting room, magnetic mineral particles are mainly tired in the upstream of magnetic medium
Product, small part directly impacts magnetic mineral accumulation region in magnetic medium builds up downstream, to mine stream, thus mechanical entrainment is more serious.This
Mechanical entrainment is reduced in utility model by magnetic medium design, key is to eliminate magnetic-particle in the accumulation of magnetic medium upstream
And strengthen magnetic-particle in the accumulation in magnetic medium downstream.By taking cylindrical magnetic medium as an example, cylindrical magnetic medium is along ore pulp flowing side
To non-magnetic portion and magnetic-conductance portion is followed successively by, i.e. the direction of cylindrical magnetic medium is what un-conducted magnetic material made to the one side in mine direction
Non-magnetic portion, the design adopted the structure, when passing through magnetic medium with non-magnetic particle to the magnetic-particle in mine, non-magnetic portion
There is no magnetic force, will not collecting magnetic-particle pass through to the substantially all never magnetic-conductance portion of mine and due to the drainage in non-magnetic portion
Without accumulating on non-magnetic portion, the accumulation of conventional magnetic medium upstream particle can be eliminated, thus is avoided to mine stream to upstream
The direct impact of the accumulation region of particle, can effectively reduce the mechanical entrainment in assorting room.When passing through magnetic-conductance portion to mine, by
In magneticaction, magnetic-conductance portion meeting active collecting completes magnetic separation process to the magnetic-particle in mine.Since magnetic-particle is situated between in magnetic
The builds up downstream of matter, support force suffered by magnetic-particle only have magnetic force, accumulation to it is a certain amount of when reach saturation, magnetic will not occur and be situated between
When the collecting of matter upstream (for magnetic-particle in addition to by magnetic force, there are also the supporting roles of magnetic medium), particle, which is constantly accumulated, leads to fluid
The phenomenon that channel blockage, therefore the Pulsating Flow of magnetic separator can be removed, cost is lower simultaneously, fluid viscosity suffered by magnetic mineral
Power reduces, and is conducive to the rate of recovery for improving fine fraction weak magnetic mineral.
