Muaj ntau yam sib txawv ntawmkub ntxhua khaub ncawsntawm kev ua lag luam hnub no. Qhov sib txawv kub ntxhua khaub ncaws yog tsim rau cov xwm txheej sib txawv. Tsis muaj ib qho me me haum rau txhua qhov kev daws teeb meem. Lub tshuab ntxhua khaub ncaws muaj 4 lub ntsiab lus tseem ceeb: tshuaj txhuam hniav, tshuab nqus tsev, cov khoom noj khoom haus thiab cov khoom nqa.
1. Cov tshuaj txhuam hniav
Scrubbers yog ib feem ntawm cov khoom siv txhuam uas sib cais cov ntaub ntawv raw thiab npaj lawv rau kev xav. Cov Scrubbers yuav tshem tawm cov pob zeb loj thiab rhuav tshem cov av nplaum loj thiab cov xuab zeb compacted. Cov tshuab ntxhua khaub ncaws feem ntau siv cov dav hlau dej los ntxuav cov pob zeb kom tshem tawm cov kub zoo uas txuas rau pebbles.
Xuab zeb thiab av nplaum adhering rau pebbles thiab pob zeb tau pom tias muaj ntau kub-nplua nuj tshaj li pob zeb tag nrho. Vim li no, nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav koj cov khoom kom huv si kom cov kub tuaj yeem ntes tau nyob rau hauv lub concentrator.
Scrubbers muaj peb lub luag haujlwm tseem ceeb:
- Kev sib cais ntawm pebbles loj thiab pob zeb los ntawm pub gravel
- Ntxuav pebbles thiab gravel
- Sib cais clods ntawm agglomerated khoom
2. Trommel
Trommel cov ntxaij vab tshaus siv rotating nruas kom agitate cov khoom. Raw gravel yog pub los ntawm ib kawg thiab dhau los ntawm kev qhib hauv lub nruas. Pob zeb loj dua qhov qhib yog kho raws li tailings. Lub nruas yog teem rau ntawm lub kaum sab xis me ntsis kom cia cov pob zeb tailings ua haujlwm los ntawm qhov kawg. Trommel cov ntxaij vab tshaus ua haujlwm zoo heev ntawm kev rhuav tshem av nplaum, av nkos, thiab pob zeb compacted.
Trommel cov ntxaij vab tshaus yog tsav los ntawm hluav taws xob lossis diesel powered motors. Lub cev muaj zog tig lub nruas los ntawm kev siv cov saw ntev nrog lub zog welded nyob ib ncig ntawm lub nruas lossis los ntawm lub log nyob ntawm lub nruas. Feem ntau cov trommels muaj cov tshuaj tsuag tsuag uas khiav hauv lub nruas thiab txau cov dej uas muaj zog tshaj cov pob zeb los pab tshem tawm cov khoom kub ntawm lub pob zeb.
Qhov luaj li cas ntawm qhov qhib yog nyob ntawm kev faib cov kub qhov ntau thiab tsawg hauv cov gravel them.
Lub trommel tuaj yeem ua ke nrog txhua hom concentrator, nws tsis tas yuav yog lub qhov dej. Trommels tuaj yeem yog qhov loj me. Trommel cov ntxaij vab tshaus yog qhov yooj yim rau kev teeb tsa thiab tuaj yeem ua ntau yam khoom siv. Ib qho ntawm lawv qhov zoo tshaj plaws ntawm lwm cov tshuaj txhuam hniav yog lawv lub peev xwm los rhuav tshem cov cement los yog cov khoom siv compacted.
3. Grizzly
Qee cov chaw ntxhua khaub ncaws tsis muaj cov tshuab sib cais, thaum lwm tus siv cov grate yooj yim. Lub grating muaj cov kab ntsug ntsug kom tso cai rau qhov loj ntawm cov khoom koj xav hla. Lub grizzly yog teem rau ntawm lub kaum sab xis kom cov pob zeb loj dua yuav tawg. thiab tej yam uas haum ntawm lub laj kab yuav dhau mus.
Kev tsim khoom qeeb qeeb thaum tsuas yog siv cov grate xwb, thiab lawv feem ntau xav tau tib neeg kev cuam tshuam los tshem tawm cov khoom siv hauv qab. Grizzlys feem ntau siv nrog rau lwm yam khoom sib cais xws li tshuaj ntsuam cov tais thiab trommels.
4. Lub thawv dej
Ntau hom sluice thawv yog siv los ntes cov kub ntshiab.
Sluice thawv tuaj yeem tswj cov khoom lag luam loj, lawv tuaj yeem ua tau loj heev thiab ntau lub sluices tuaj yeem khiav ua ke los tuav ntau dua. Lub ntiaj teb cov chaw ntxhua khaub ncaws loj tshaj plaws ua haujlwm ntau lub qhov rooj sluice. Tag nrho cov xauv yuav tsum tau ua tib zoo teeb tsa thiab ntau tweaking kom ntseeg tau tias lawv sau tag nrho cov kub. Lub xauv shoals thaum kawg yuav sau nrog cov xuab zeb dub, ua rau nws tsis yooj yim rau lauj kaub kub, yog li lub thawv dej yuav tsum tau ntxuav tsis tu ncua.
