With reference to figure 4, ore pulp is sorting in cylinder 28 in rotary course and can generate vortex at center, causes to sort fluid in cylinder 28
It is unstable, and with the increase for sorting 28 diameter of cylinder, the intensity of vortex is bigger；The vortex of generation can be by a large amount of impurity and concentrate one
It rises and is brought down into deposited tube 33, the concentrate formed in deposited tube causes separation index unqualified doped with a large amount of impurity.
So in order to avoid sorting cylinder 28 because ore pulp is rotated in and being centrally formed whirlpool, the whirlpool prevented is in the same direction impurity and concentrate one
Lower transport to deposited tube 33 forms concentrate discharge, and the adverse consequences for causing concentrate grade to decline is sorting the centrally disposed cylinder of cylinder
Shape inner cylinder 30；But it is not limited to cylindrical inner cylinder 30, inner cylinder 30 can also be the different truncated cone-shaped of upper and lower diameter.Inner cylinder 30

It is adjustable.Top continues magnetic field 53 for capturing the high-grade magnetic-particle that will enter overflow launder 2, prevents magnetic of high-grade
Grain enters tailing.Lower part, which continues magnetic field 56, has the reunion for promoting magnetic-particle in deposited tube 33, improves the deposition of magnetic-particle
Speed adjusts the effect of the concentrate concentration of final concentrate.Coil in pulsation coil group 55 is sequentially generated unidirectional arteries and veins from top to bottom
Moving field forms the downlink magnetic field walked from top to bottom.Downlink magnetic field is used to make to enter the magnetic-particle for sorting cylinder 28 and be formed
Magnetic linkage.Magnetic linkage deposits downwards to deposited tube 33 under the impulse force collective effect of downlink magnetic field, gravity and water and ultimately forms concentrate row
Go out.The coil of pulsation coil group 55 is sequentially generated two-way pulsating field, shape to downlink magnetic fields from bottom to top later for a period of time
Reversely magnetic field is broken up at what is walked from bottom to top.Because the size of two-way pulsating field and the direction in magnetic field constantly change, magnetic
The magnetic force that property particle is subject to can constantly change with the variation of two-way pulsating field.Effect of the magnetic-particle in two-way pulsating field
It is lower to shake.Adjust the size of two-way pulsating field, the action period can enhance the effect of shake finally magnetic linkage is made to scatter.Magnetic
Chain can release the impurity being mingled with after scattering.It reversed broken up magnetic field by what two-way pulsating field was formed and is being sorted by some cycles
Magnetic linkage is carried out in area from bottom to top to break up.After reversely breaing up magnetic fields, downlink magnetic field is run.The downlink magnetic field run again
So that high-grade magnetic-particle is agglomerated into magnetic linkage again and deposits downwards.Magnetic is actively broken up using the magnetic field force for reversely breaing up magnetic field
Chain is more water-saving than relying on the impact of the presence or absence of magnetic field or water to break up magnetic linkage merely.
