Different magnetic field combined wet-type strong magnetic separator of the present invention be on the basis of existing SHP type series double plate Wet-type strong magnetic separator, carry out improved, main feature is that three of will be from top to bottom vertically arranging and three above sorting rotating disks are provided with corresponding magnetic induction intensity by the magnetic scope segmentation of material respectively, and is device for these magnetic induction intensity require to design corresponding magnetic.
Uppermost first separator plate is mainly used in selects ferromagnetism thing in the ore pulp and the stronger material of magnetic, so this separator plate need dispose the magnetic pole that produces low-intensity magnetic field, work magnetic induction intensity is generally 1~2000 Gauss, this magnetic pole is a secondary magnetic pole, a part of magnetic field is isolated in its paired last cartridge top from main pole, make sorting rotating disk magnetic circuit and the magnetic circuit of isolating the next sorting rotating disk of magnetic pole form route in parallel, again with other following sorting rotating disk magnetic circuit formation series relationship.This structure makes the high intensity magnetic separation sorting rotating disk of back produce different magnetic induction intensity, so be called different magnetic field combined wet-type strong magnetic separator.Because each the sorting rotating disk that forms from top to bottom has the work magnetic induction intensity that has nothing in common with each other, can be exclusively used in serial sorting ore pulp material, both from assembling the obstruction that forms from solving the magnetic that is produced because of magnetization at all on one's body, on an equipment, carry out repeatedly magnetic separation again, can require to carry out that concentrate selects again or mine tailing is scanned with technological process, or both finished concentrate and selected again and also finish mine tailing and scan, become relatively comprehensively magnetic separator of a function.
Be provided with every screen system at the magnetic separator front end, can solve owing to do not have configuration to stop up the problem in separating medium slit every sieve or the screening thick thing that administrative vulnerability caused in the technological process usually.
Different magnetic field combined wet-type strong magnetic separator of the present invention, owing to be provided with specially and the supporting weak magnetic separation secondary magnetic pole of going up most of sorting rotating disk, assemble the high intensity magnetic separation dish rotating disk separating medium case blockage problem that forms thereby thoroughly solved in the actual production, improved the production efficiency of magnetic separator significantly because of the magnetic that is produced that in high-intensity magnetic field, is magnetized of magnetic thing a little less than ferromagnetism thing in the material and the illusion.Sorting dial feed front end increase special configuration every sieve, can also solve broken silk ribbon in the ore pulp, leaf grass roots and coarse granule and enter in the separating medium slit the thick thing blockage problem that accumulation day by day forms.A plurality of rotating disk magnetic induction intensity of Pai Lieing progressively increase from top to bottom, can produce 3000~17000 Gausses in strong and high-intensity magnetic field, can satisfy the requirement that material magnetic to be selected selects more weak and more weak needed relevant work magnetic induction intensity, and can finish and on an equipment, carry out function selected and/or that scan.
Be that example further specifies technical scheme of the present invention in conjunction with the accompanying drawings with three dish combined types below.
