Tom qab lub sijhawm ua haujlwm ntev, lub pob zeb yuav ntau dua los yog tsawg dua qhov teeb meem ntawm kev sib tsoo kom zoo, uas tsis tsuas yog cuam tshuam rau kev ua haujlwm ntawm tag nrho cov concentrator, tab sis kuj ua rau cov txiaj ntsig kev lag luam ntawm tus tswv mine. Yog li, hauv kev xyaum ntau lawm, peb tuaj yeem txhim kho qhov kev sib tsoo zoo ntawm pob mills li cas? Nov yog xya txoj hauv kev pib.
1. Txhim kho cov grindability ntawm raw ore
Feem ntau, lub hardness, degree ntawm dissociation, qhov loj thiab cov qauv ntawm cov raw ore txiav txim lub grindability ntawm raw ore. Lub grindability yog me me, qhia tau hais tias cov raw ore yog ib qho yooj yim rau grind, thiab hnav ntawm lub pob zeb hauv ob sab phlu phaj thiab sib tsoo nruab nrab yog me me, thiab lub zog noj yog tsawg. Lub grindability yog loj, qhia tau hais tias cov raw ore yog nyuaj rau grind, thiab hnav lub pob zeb hauv ob sab phlu phaj thiab sib tsoo nruab nrab kuj loj, thiab lub zog noj yog siab. Nws tau pom tias kev sib tsoo ntawm cov ore raw yuav cuam tshuam ncaj qha rau kev sib tsoo ntawm lub pob zeb.
Yog li ntawd, nyob rau hauv ntau lawm, thaum lub raw ore yog nyuaj rau grind thiab particle loj yuav tsum tau zoo, peb muaj peev xwm coj tej yam kev ntsuas los txhim kho lub grindability ntawm raw ore yog hais tias kev lag luam thiab qhov chaw tso cai, xws li ntxiv tshuaj nyob rau hauv kev sib tsoo. txheej txheem kom cov kev sib tsoo efficiency; Los yog ua hauj lwm lub grindability ntawm raw ore: cua sov cov minerals nyob rau hauv cov raw ore, txo cov hardness, thiab lwm yam.
2. Sib tsoo ntau dua thiab zom tsawg dua, txo qhov sib tsoo particle loj ntawm lub pob zeb
Qhov loj dua qhov sib tsoo me me, qhov ntau dua qhov kev ua haujlwm ntawm lub pob zeb ntawm cov ore, thiab kev sib tsoo zoo ntawm lub pob zeb yuav raug cuam tshuam. Txhawm rau kom ua tiav qhov tsim nyog sib tsoo fineness, kev ua haujlwm ntawm lub pob zeb yog khi kom nce, thiab kev siv zog kuj yuav nce ntxiv.
Yog tias cov khoom noj yuav tsum raug txo kom tsawg, cov khoom crushed loj yuav tsum me me, uas yog, "ntau crushing thiab tsawg sib tsoo", yog li ntawd lub feed loj yog tsim nyog, thiab kev sib tsoo efficiency ntawm lub pob zeb yuav zoo dua.
3. Ua kom haum steel pob filling tus nqi
Thaum qhov ceev ntawm lub pob zeb tau tswj hwm ntawm ib theem, qhov loj dua qhov ntim ntawm lub pob steel, qhov kev sib tsoo ntau dua yuav nyob ntawm cov khoom siv, qhov sib tsoo yuav nce ntxiv, thiab kev sib tsoo ua haujlwm ntawm lub ntiaj teb zeb yuav kuj tau txhim kho, tab sis tib lub sijhawm, kev siv hluav taws xob kuj tseem loj. Txawm li cas los xij, yog tias qhov ntim ntawm lub pob steel siab dhau lawm, nws yog ib qho yooj yim ua rau lub xeev ntawm lub pob steel hloov, tab sis nws txo qhov cuam tshuam rau cov khoom loj. Hauv kev xyaum ua ntau lawm, feem ntau cov mines yuav teeb tsa tus nqi ntawm 45% ~ 50%, tab sis qhov no tsuas yog qhov dav dav, vim tias qhov tseeb ntawm txhua qhov chaw sib txawv, thiab qhov muag tsis pom kev yuav tsis tau txais kev sib tsoo zoo tagnrho, nyob ntawm qhov xwm txheej.
4. Tsim nyog ntxiv cov pob steel
Nyob rau hauv cov txheej txheem ntawm kev ua haujlwm ntev, kev sib tsoo ntawm cov pob steel thiab cov pob zeb ntawm lub pob zeb yuav ua rau qee qhov kev hnav ntawm cov pob steel, uas ua rau muaj kev hloov pauv ntawm qhov sib piv ntawm cov pob steel ntawm qhov sib txawv, ua rau Cov kev hloov pauv hauv kev ua kom zoo ntawm cov khoom sib tsoo, thiab tom qab ntawd cuam tshuam rau kev sib tsoo efficiency ntawm lub pob zeb. Yog li ntawd, tus neeg teb xov tooj pob zeb yuav tsum tsis tu ncua xyuas qhov xwm txheej ntawm cov pob hlau, thiab tsim nyog ntxiv cov pob hlau kom ntseeg tau tias cov khoom ruaj khov ntawm lub pob zeb.
5. nruj me ntsis tswj kev sib tsoo concentration ntawm lub pob zeb
Feem ntau, qhov sib tsoo concentration cuam tshuam rau lub ntiajteb txawj nqus ntawm slurry, fluidity ntawm slurry, thiab adhesion ntawm ore hais rau lub pob steel. Kev sib tsoo cov ntsiab lus qis, slurry ntws nrawm, thiab cov khoom siv tsis yooj yim los lo ntawm lub pob steel, uas ua rau muaj kev cuam tshuam thiab kev sib tsoo ntawm cov khoom, uas ua rau cov khoom tsis tsim nyog ore paug particle loj thiab tsis tshua muaj kev sib tsoo ntawm lub pob. zeb; Kev sib tsoo concentration yog siab, thiab cov khoom siv yooj yim rau puag ncig lub pob steel, uas txhim kho qhov cuam tshuam thiab kev sib tsoo ntawm cov khoom siv, tab sis cov slurry ntws qeeb, uas yooj yim ua rau overgrinding.
Nyob rau hauv kev xyaum ntau lawm, kev sib tsoo concentration yog tswj los ntawm kev tswj cov ore pub ntawm lub pob zeb thiab cov dej pub ntawm lub pob zeb, los yog kho thiab tswj cov particle loj muaj pes tsawg leeg thiab noo noo nyob rau hauv cov qib xuab zeb rov qab, thiaj li yuav pab txhim kho kev sib tsoo. efficiency ntawm lub pob zeb.
6. Txhim kho cov txheej txheem sib tsoo ntawm pob zeb
Raws li cov khoom siv ntawm cov khoom siv raw ntawm cov ore (paub cov ntxhia hauv qhov loj me, monomer dissociation degree, gangue ntxhia embedding particle loj) kom ua kom zoo dua cov txheej txheem sib tsoo, xws li ua ntej tailing, pre-enrichment, theem sib tsoo, pre-classification, ntawm ntawm ib sab tes, txo cov nyiaj sib tsoo, ntawm qhov tod tes, lub sij hawm rov qab los ntawm cov zaub mov muaj txiaj ntsig, tuaj yeem txhim kho kev sib tsoo efficiency ntawm pob zeb.
7. Txhim kho cov qhab nia zoo
Qhov cuam tshuam ntawm kev muab qhab nia ntawm kev sib tsoo efficiency yog qhov tseeb ntawm tus kheej. High grading efficiency txhais tau hais tias qhov tsim nyog particle loj tuaj yeem raug tso tawm raws sijhawm thiab ua haujlwm tau zoo, thaum qhov kev ua haujlwm qis qis txhais tau hais tias feem ntau ntawm cov khoom tsim nyog tsis tuaj yeem raug tso tawm thiab xa rov qab mus rau lub pob zeb rau rov sib tsoo, uas yooj yim rau kev sib tsoo. ua rau overgrinding. Nyob rau hauv ntau lawm, ob-theem grading los yog txhim kho grading cov cuab yeej siv tau los txhim kho cov qhab nia efficiency, thiab kev sib tsoo efficiency ntawm lub pob zeb tuaj yeem txhim kho raws li.
