Coal enrichment - nta, thev naus laus zis, cov cai thiab cov tswv yim

2024 Tus sau: Howard Calhoun | [email protected]. Kawg hloov kho: 2023-12-17 10:28

Cov thee tawv, uas yog mined hauv mines underground, xav tau txheej txheem ua ntxiv. Coal enrichment yog tsim nyog vim hais tias raw cov ntaub ntawv mined underground muaj ntau yam tsis tsim nyog impurities.

cov ntaub ntawv dav dav

Vim li cas kev nplua nuj thiaj tseem ceeb? Tag nrho vim lub fact tias cov impurities tam sim no nyob rau hauv cov ntaub ntawv no yuav muab ib tug tsawg combustion kub yog hais tias koj pib siv lawv. Yog li, nws hloov tawm hais tias koj yuav tau hlawv ib tug loj npaum li cas ntawm cov thee, uas yuav muab ib tug tsawg combustion kub. Kev nplua nuj ntawm cov thee yog kev ua kom huv ntawm cov khoom siv raw los ntawm txhua yam khoom tsis tsim nyog uas cuam tshuam nrog nws cov combustion.

Thaum tus txheej txheem no, ntau lub hom phiaj tau ua tiav. Ua ntej, cov zaub mov thiab impurities raug tshem tawm, thiab thib ob, cov mined thee muab faib ua feem raws li qhov loj thiab qib ntawm cov nplej. Tsuas yog tom qab dhau los ntawm cov txheej txheem no thiab kuaj xyuas qhov zoo ntawm cov khoom kawg, thee raug xa mus rau cov neeg siv khoom.

Nkauj thiab ntub sib cais

Cov txheej txheem ntawm cov thee enrichment suav nrog ntau theem. Thawj qhov ntawm cov no yog kev tshuaj xyuas, lossis kev sib cais ntawm cov khoom siv raw rau hauvfeem ntawm qhov loj thiab qib. Txhawm rau kom ua tiav cov txheej txheem tseem ceeb, cov khoom siv xws li lub vijtsam vibrating yog siv. Qhov no yog ib tug loj sieve. Feem ntau, muaj ob peb ntawm lawv ntawm cov nroj tsuag enrichment, thiab lawv lub ntsiab sib txawv nyob rau hauv qhov loj ntawm lub hlwb. Tau txais ntawm cov ntxaij vab tshaus nrog cov hlwb sib txawv, cov thee tau muab faib ua ob peb pawg. Yog tias peb tham txog kev faib cov thee los ntawm qhov loj me, ces muaj cov txheej txheem lees paub uas suav nrog ntau hom - noob, txiv ntoo, thiab lwm yam.

Ib hom kev npaj cov thee feem ntau yog ntub dej. Cov txheej txheem no yog ua raws li lub hauv paus ntsiab lus ntawm kev sib cais ceev. Txij li cov impurities muaj qhov ntsuas qis dua ntawm qhov ntsuas no, thiab cov thee muaj qhov loj dua, lawv qhov kev sib cais yuav tshwm sim hauv cov dej ib puag ncig. Cov tshuab uas cov txheej txheem no tau ua yog hu ua jigging machine. Cov cuab yeej no belongs rau lub ntiajteb txawj nqus enrichment devices.

khoom

Cov khoom siv raw siv los ua cov haujlwm no hu ua zaub mov. Thaum lub sij hawm ua cov khoom siv pob zeb, koj tuaj yeem tau txais cov khoom siv hluav taws xob zoo li no:

• Ua kom pom tseeb. Qhov no yog lub npe ntawm cov khoom lag luam uas tau khaws cov khoom siv hluav taws xob ntau tshaj plaws hauv lawv cov muaj pes tsawg leeg, thiab cov ntsiab lus ntawm cov khoom siv pob zeb tau txo qis mus rau qhov tsawg kawg nkaus.
• khoom. Cov khoom siv raw no yog cov khoom nruab nrab. Cov ntsiab lus ntawm combustible tshuaj nyob rau hauv nws tsis ncav cuag nws qhov siab tshaj plaws tus nqi, tab sis tus nqi ntawm pob zeb Cheebtsam tsis nce ntau dhau. Cov khoom zoo li noKev ua tiav yog suav tias tsis tiav thiab xav tau kev ua tiav ntxiv.
• Mixed, lossis pov tseg. Nrog rau cov khoom siv raw no, txhua yam ua tiav los ntawm nws lub npe - cov ntsiab lus ntawm cov khoom siv hluav taws xob tsawg tsawg, thiab cov khoom siv pob zeb yog qhov siab tshaj plaws.

Coal ntxhua khaub ncaws

Cov neeg koom nrog muaj ntau yam txheej txheem sib txawv, uas tau muab faib ua pawg nyob ntawm lawv lub hom phiaj thev naus laus zis.

thawj qeb yog cov txheej txheem npaj. Lub luag haujlwm tseem ceeb ntawm theem no yog qhia cov khoom ntawm cov pob zeb loj, faib rau hauv cov chav kawm tshuab, thiab lwm yam. Cov theem no suav nrog cov kev ua haujlwm xws li kev tshuaj ntsuam xyuas thiab crushing. Yog hais tias peb tham txog cov txheej txheem crushing, ces nws yog heev yooj yim. Lub luag haujlwm ntawm theem no yog txhawm rau rhuav tshem cov pob zeb uas twb muaj lawm rau qhov loj me. Rau qhov no, sab nraud quab yuam siv, uas yog, cov cuab yeej tshwj xeeb. Kev tshuaj xyuas, raws li tau hais ua ntej, yog txheej txheem rau kev cais cov pob zeb rau hauv cov chav kawm los ntawm qhov loj me.

Tom qab ua tiav qhov kev npaj ua tiav, koj tuaj yeem mus rau qhov tseem ceeb, txoj haujlwm uas yog cais cov khoom siv ntawm cov thee rau hauv kev mloog zoo, nruab nrab lossis sib xyaw.

Tam sim no, pob zeb tau txais txiaj ntsig cov nroj tsuag siv hom kev nqus tau txiaj ntsig zoo li jigging, ntsia hlau thiab sib cais sib cais, hnyav slurry beneficiation.

Qee qhov chaw siv thee ntxhua khaub ncaws uas ua cov txheej txheem flotation. Lub essence ntawm technologyenrichment nyob rau hauv txoj kev no nyob rau hauv qhov tseeb hais tias qhov sib txawv ntawm lub cev thiab tshuaj zog ntawm cov thee thiab impurities yog siv.

Cov txheej txheem pabcuam

Ntxiv rau cov txheej txheem tseem ceeb, ob peb lub koom haum pab tau siv rau ntawm cov nroj tsuag ntxiv. Cov no suav nrog kev ua haujlwm kom lub cev qhuav dej lossis desusting.

Ib txwm, cov txheej txheem lub cev qhuav dej tsuas yog siv tau rau cov khoom siv ntxiv uas tau dhau los ntawm kev kho lub ntiajteb txawj nqus. Ob peb txoj kev sib txawv yog siv los ua kom tiav txoj haujlwm no. Cov khoom loj, ntau dua 13 hli, yog dewatered ntawm cov ntxaij vab tshaus, elevator lossis hauv cov kav dej. Crayons ntawm tib hom kev kawm mus dhau cov txheej txheem ntawm centrifugation, thiab nyob rau lub caij ntuj no kuj thermal ziab ntawm cov khoom.

Dedusting yog txheej txheem rau cais cov hmoov av me dua 0.5 hli los ntawm cov thee. Txhawm rau ua tiav txoj haujlwm no, siv ob txoj hauv kev. Txoj kev ntub dej - cov ntxaij vab tshaus lossis hydrocyclones yog siv. Txoj kev qhuav siv cov cua cais nrog cov qauv sib txawv.

Coal ntxuav schemes

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov ntawm no tias tsis muaj ib qho tswv yim rau kev txhawb nqa. Nyob rau hauv txhua rooj plaub, koj yuav tsum xaiv los ntawm ntau yam kev xaiv muaj. Cov kev txiav txim siab uas cuam tshuam rau qhov tshwm sim yog cov khoom ntawm ore nws tus kheej, nrog rau nws lub hom phiaj.

Piv txwv li, yog tias peb tham txog qhov tob ntawm kev nplua nuj, ces muaj ob peb lub tswv yim hauv qab no:

• Thawj txoj kev suav nrog kev txhawb nqa ntawm tsuas yog qhov loj tshaj plaws,qhov loj ntawm qhov ntau tshaj 25 (13) mm. Kev xa khoom tom qab ntawm pob zeb yog ua los ntawm kev sib koom ua ke, uas yog, ob qho tib si mloog zoo thiab pov tseg raug xa mus ua ke, lossis cais.
• Txoj kev thib ob yog kev txhawb nqa ntawm cov pob zeb hauv nruab nrab ntawm qhov loj ntawm ntau tshaj 6 (3) hli. Kev sib cais ntawm cov khoom tau txais kuj tuaj yeem ua ke los yog sib cais.

Kuj tseem muaj kev faib ua ob peb lub tswv yim, nyob ntawm qhov zoo ntawm cov concentrate tau txais thaum txhawb nqa. Ib qho ntawm cov txheej txheem thev naus laus zis tshaj plaws ntawm hom no yog kev tso tawm ntawm ib qho khoom lag luam. Nws tsuas yog siv rau kev txhawb nqa ntawm thermal thee ntawm cov qib zoo li no, uas thaum lub sijhawm ua cov txheej txheem tsis tau faib ntau chav kawm los ntawm qhov loj me. Ib qho piv txwv zoo ntawm cov tswv yim zoo li no yog thee cim P.

Rules

Qhov tseeb, muaj ob peb txoj cai rau kev tsim cov thee. Yuav kom meej, nws tsuas yog ib qho, tab sis tseem ceeb heev, thiab nyob rau hauv lub fact tias nws yog tsim nyog los soj ntsuam tag nrho cov txheej txheem ntau lawm thaum lub sij hawm ua cov pob zeb. Xws li cov txheej txheem yuav tsum muaj xws li kev faib ua feem ntau thiab ncaj qha ntxiv cov khoom. Txij li thaum yug me nyuam tsis tuaj yeem yog qhov loj tib yam, nws tau muab faib ua qhov loj, nruab nrab thiab me, tom qab ntawd nws raug xa mus rau theem tshuaj ntsuam.
