Cov txheej txheem yog qhov nyuaj dua, yuav tsum tau cia siab rau dej ua qhov nruab nrab rau kev xaiv. Cov khoom siv sib nqus ntub dej sib nqus muaj xws li: cov khoom siv ntub dej sib nqus sib nqus (magnetic dewatering tank, ruaj khov hlau nplaum lub tog raj kheej hom sib nqus sib nqus), cov khoom sib nqus ntub dej sib nqus (ntub induction yob hom sib nqus sib nqus, Jones hom magnetic separator, tiaj tus nplhaib sib nqus sib nqus). Raws li cov qauv tank tuaj yeem muab faib ua cov dej sib nqus sib nqus dej hauv qab, qhov sib txawv thiab ib nrab countercurrent hom peb.
Cov sib nqus sib nqus ntub dej txuag lub zog thiab txo kev noj, tuaj yeem siv cov hlau tsis tshua muaj hlau ore thiab txhim kho qhov zoo ntawm cov hlau kawg nkaus. Feem ntau siv rau qib zoo sib nqus thiab tsis muaj zog hlau nplaum ore thiab hlau hmoov xaiv. Ob feem ntau siv cov hlau nplaum sib nqus sib nqus yog down-flow magnetic separators thiab semi-countercurrent magnetic separators.
Down-flow magnetic separator hais txog cov kev taw qhia ntawm kev txav mus los thiab cov kev taw qhia ntawm lub tog raj kheej txav los yog cov khoom txav. Pulp los ntawm lub thawv pub ncaj qha rau hauv lub tog raj kheej sib nqus hauv qab no, cov khoom tsis muaj hlau nplaum thiab cov hlau nplaum tsis muaj zog tawm los ntawm qhov sib txawv hauv qab lub tog raj kheej, cov khoom sib nqus tau nqus rau ntawm lub tog raj kheej, nrog lub tog raj kheej tig mus rau ntawm ntug ntawm cov hlau nplaum. tsis muaj zog, los ntawm cov yeeb nkab dej tawm mus rau lub tank concentrate. Lub downstream magnetic separator muaj peev xwm ua tau loj thiab tuaj yeem siv tau rau hauv series. Nws yog tsim rau roughing thiab xaiv ntawm ntxhib muaj zog hlau nplaum ore nrog particle loj 0 ~ 6mm thiab kuj siv tau rau recovering sib nqus hnyav xov xwm.
Semi - countercurrent magnetic separator muaj ntau dua concentrated zoo thiab hlau rov qab. Lub slurry yog xoob tshem tawm mus rau hauv qhov chaw sorting nyob rau hauv lub tank lub cev, thiab cov kev taw qhia ntawm slurry zog yog yeej ib yam li cov sib nqus quab yuam. Yog li ntawd, cov khoom siv ore tuaj yeem ncav cuag qhov chaw ntawm lub tog raj kheej nrog lub zog sib nqus, thiab cov tailings tau tawm ntawm lub qhov tailings ntawm lub phaj hauv qab, kom cov dej ntws tawm qhov siab tuaj yeem tswj tau qib ntawm slurry hauv lub tank lub cev. Semi-countercurrent magnetic separator yog dav siv los cuam tshuam nrog cov khoom zoo (tsawg dua 0.2mm) ntawm cov hlau nplaum muaj zog roughing kev ua haujlwm thiab kev xaiv ua haujlwm, tuaj yeem siv ua ke nrog ntau dua, txhim kho qib siab.
Kev xaiv ntawm magnetic separator yog ib qho kev txiav txim siab ntawm qhov teeb meem, xav paub seb hom hlau nplaum sib nqus yuav tsum siv li cas, lossis yuav tsum tau mus dhau ntawm cov txheej txheem xws li kev sim txiaj ntsig lossis kev sab laj cov kws tshaj lij kev lag luam, raws li qhov xwm txheej tshwj xeeb ntawm sib txawv mines.
