Yam cuam tshuam rau kev sib tsoo efficiency ntawm pob zeb

Kev sib tsoo ua haujlwm ntawm lub pob zeb yog cuam tshuam los ntawm ntau yam, ntawm qhov tseem ceeb yog: daim ntawv txav ntawm lub pob steel hauv lub tog raj kheej, qhov nrawm ntawm kev sib hloov, qhov sib ntxiv thiab qhov loj ntawm lub pob steel, qib ntawm cov khoom siv. , kev xaiv ntawm lub liner thiab kev siv cov khoom sib tsoo. Cov yam tseem ceeb no muaj kev cuam tshuam rau kev ua haujlwm ntawm lub pob zeb rau qee yam.

Rau ib qho twg, cov lus tsa suab ntawm kev sib tsoo nruab nrab hauv lub tog raj kheej cuam tshuam rau kev sib tsoo ntawm lub pob zeb. Qhov chaw ua haujlwm ntawm lub pob zeb tau muab faib ua pawg hauv qab no:
(1) Nyob rau hauv qhov chaw nyob ib puag ncig thiab poob qis, qhov ntim ntim hauv lub tog raj kheej tsawg dua los yog tsis muaj, yog li cov khoom siv tuaj yeem ua cov voj voog ncig lossis poob txav hauv lub tog raj kheej, thiab qhov cuam tshuam qhov tshwm sim ntawm lub pob steel thiab cov hlau. pob loj dua, ua rau hnav ntawm lub pob steel thiab lub liner, ua rau lub pob zeb tsis zoo;
(2) Muab tso rau hauv qhov chaw txav, sau cov nyiaj tsim nyog. Lub sijhawm no, lub pob steel muaj kev cuam tshuam rau cov khoom siv, ua rau lub pob zeb ua haujlwm zoo heev;
(3) Nyob rau hauv thaj tsam ntawm qhov chaw ntawm lub pob zeb, lub voj voog ncig ntawm lub pob steel los yog kev sib xyaw ntawm kev poob thiab ntuav ua rau qhov kev txav ntawm cov pob hlau tsis muaj zog, thiab qhov hnav thiab cuam tshuam me me;
(4) Nyob rau hauv qhov chaw khoob, lub pob hlau tsis txav, yog tias qhov ntim ntau dhau lawm, lub pob steel txav ntau me me los yog tsis txav, ces nws yuav ua rau cov khoom siv khib nyiab, yooj yim rau lub pob zeb. ua tsis tiav.
Nws tuaj yeem pom los ntawm (1) tias thaum lub ntim ntim tsawg heev lossis tsis muaj, lub pob zeb raug kev poob loj, uas feem ntau yog los ntawm kev cuam tshuam ntawm lub pob steel ntawm cov khoom. Tam sim no lub pob zeb dav dav yog kab rov tav, txhawm rau txo qhov poob ntawm lub pob zeb kom tsis muaj khoom siv, muaj lub pob zeb ntsug.
Nyob rau hauv cov khoom siv pob zeb tsoos, lub tog raj kheej ntawm lub pob zeb yog tig, thaum lub tog raj kheej ntawm cov khoom siv sib xyaw yog nyob ruaj ruaj, uas feem ntau yog nyob ntawm cov khoom siv sib xyaw ua ke los cuam tshuam thiab do cov pob hlau thiab cov khoom hauv lub thoob. Lub pob thiab cov ntaub ntawv tig nyob rau hauv cov khoom siv nyob rau hauv qhov kev txiav txim ntawm ntsug sib tov khoom, kom cov khoom tsuas ua rau lub pob steel kom txog thaum nws crushed. Yog li nws yog qhov tsim nyog rau kev sib tsoo zoo thiab kev sib tsoo zoo.

02 Ceev Ib qho tseem ceeb ua haujlwm ntawm lub pob zeb yog qhov ceev, thiab qhov kev ua haujlwm no ncaj qha cuam tshuam rau kev sib tsoo ntawm lub pob zeb. Thaum xav txog qhov kev sib hloov, tus nqi filling yuav tsum tau txiav txim siab. Lub filling tus nqi yog zoo correlated nrog tus nqi sib hloov. Khaws tus nqi sau kom tas mus li thaum tham txog tus nqi tig ntawm no. Txawm hais tias lub xeev cov lus tsa suab ntawm lub pob nqi yog dab tsi, yuav muaj qhov kev sib hloov tsim nyog tshaj plaws nyob rau hauv ib qho kev sau tus nqi. Thaum tus nqi ntim tau ruaj khov thiab qhov kev sib hloov qis qis, lub zog tau txais los ntawm lub pob steel yog qhov tsawg, thiab qhov cuam tshuam lub zog ntawm cov khoom siv tsawg, uas tej zaum yuav qis dua tus nqi ntawm cov ore crushing thiab ua rau muaj kev cuam tshuam tsis zoo ntawm cov ore. hais, uas yog, ore particles yuav tsis tawg, yog li kev sib tsoo efficiency ntawm tsawg ceev yog tsawg. Nrog rau qhov nce ntawm qhov nrawm, qhov cuam tshuam lub zog ntawm lub pob steel cuam tshuam rau cov khoom nce, yog li ua rau cov crushing nqi ntawm ntxhib ore hais, thiab tom qab ntawd txhim kho kev sib tsoo efficiency ntawm lub pob zeb. Yog tias qhov nrawm txuas ntxiv mus ntxiv, thaum ze rau qhov tseem ceeb ceev, cov khoom lag luam ntxhib tsis yooj yim tawg, qhov no yog vim tias tom qab qhov nrawm dhau lawm, txawm hais tias qhov cuam tshuam ntawm lub pob hlau tuaj yeem nce ntxiv, tab sis tus naj npawb ntawm cov voj voog. ntawm lub pob steel poob ntau heev, tus naj npawb ntawm steel pob cuam tshuam rau ib chav tsev lub sij hawm txo, thiab crushing tus nqi ntawm coarse ore hais tau txo.

03 Qhov sib ntxiv thiab qhov loj ntawm cov pob steel
Yog hais tias tus nqi ntawm cov pob steel ntxiv tsis tsim nyog, lub pob kab thiab qhov sib piv tsis tsim nyog, ces nws yuav ua rau txo qis kev sib tsoo. Kev hnav ntawm lub pob zeb hauv cov txheej txheem ua haujlwm yog qhov loj, thiab feem ntau ntawm qhov laj thawj yog vim li cas cov khoom siv hlau tsis muaj kev tswj xyuas zoo, uas ua rau cov khoom sib txuam ntawm cov pob steel thiab qhov tshwm sim ntawm cov nplaum nplaum, thiab tom qab ntawd ua rau cov khoom sib xyaw ua ke ntawm cov pob zeb steel. ib yam hnav rau lub tshuab. Raws li lub ntsiab sib tsoo nruab nrab ntawm pob zeb, nws yog ib qho tsim nyog los tswj tsis tau tsuas yog tus nqi ntawm cov pob steel ntxiv tab sis kuj nws qhov piv. Kev ua kom zoo ntawm kev sib tsoo nruab nrab tuaj yeem ua rau kev sib tsoo zoo li ntawm 30%. Nyob rau hauv tus txheej txheem ntawm kev sib tsoo, qhov cuam tshuam hnav yog loj dua thiab kev sib tsoo hnav me dua thaum lub pob kab taub loj dua. Lub pob taub me me, qhov cuam tshuam hnav me me, kev sib tsoo hnav yog loj. Thaum lub pob lub taub loj dhau lawm, tus naj npawb ntawm cov khoom thauj hauv lub tog raj kheej raug txo, qhov sib tsoo ntawm lub pob yog qhov me me, thiab qhov hnav ntawm liner thiab kev noj ntawm lub pob yuav nce ntxiv. Yog hais tias lub pob taub me dhau lawm, cov nyhuv cushioning ntawm cov khoom nce, thiab qhov cuam tshuam kev sib tsoo yuav tsis muaj zog.
Txhawm rau txhawm rau txhim kho kev sib tsoo, qee cov neeg tau muab tso rau hauv cov txheej txheem ua pob pob:
(l) Sieve tsom xam ntawm cov ores tshwj xeeb thiab pab pawg raws li qhov loj me;
(2) Lub crushing tsis kam ntawm cov ore yog soj ntsuam, thiab lub caij nyoog pob txoj kab uas hla yuav tsum tau los ntawm txhua pab pawg neeg ntawm ore hais yog xam los ntawm lub pob txoj kab uas hla semi-theoretical mis;
(3) Raws li cov yam ntxwv muaj pes tsawg leeg ntawm qhov loj me ntawm cov khoom yuav tsum tau ua hauv av, lub hauv paus ntsiab lus ntawm crushing statistical mechanics yog siv los coj lub pob muaj pes tsawg leeg, thiab qhov sib piv ntawm ntau lub pob steel yog ua los ntawm lub hauv paus ntsiab lus ntawm qhov siab tshaj plaws. crushing tshwm sim;
4) Lub pob yog xam raws li lub hauv paus ntawm lub pob suav, thiab cov hom pob tau txo qis thiab 2 ~ 3 yam ntxiv.

04 Khoom qib
Cov qib ntawm cov khoom cuam tshuam rau kev sau tus nqi, uas yuav cuam tshuam rau kev sib tsoo ntawm lub pob zeb. Yog tias cov khoom siv qib siab dhau lawm, nws yuav ua rau cov thee thaiv hauv lub pob zeb. Yog li ntawd, kev saib xyuas zoo ntawm cov khoom siv qib tseem ceeb heev. Nyob rau tib lub sijhawm, kev siv lub zog ntawm lub pob zeb kuj tseem cuam tshuam nrog cov khoom siv. Rau qhov nruab nrab cia pulverizing system, lub zog siv ntawm lub pob zeb suav txog li 70% ntawm lub zog siv ntawm lub tshuab pulverizing thiab li ntawm 15% ntawm lub zog siv ntawm cov nroj tsuag. Muaj ntau yam cuam tshuam rau qhov nruab nrab cia pulverization system, tab sis nyob rau hauv kev cuam tshuam ntawm ntau yam, kev soj ntsuam zoo ntawm cov khoom siv yog qhov tsim nyog heev.

05 Xaiv ib lub liner
Lub hauv paus phaj ntawm lub pob zeb tuaj yeem tsis tsuas yog txo qhov kev puas tsuaj ntawm lub tog raj kheej, tab sis kuj hloov lub zog mus rau qhov sib tsoo nruab nrab. Ib qho ntawm cov xwm txheej cuam tshuam rau kev sib tsoo ntawm lub pob zeb yog txiav txim siab los ntawm kev ua haujlwm ntawm lub liner. Hauv kev xyaum, nws paub tias txhawm rau txo lub tog raj kheej kev puas tsuaj thiab txhim kho kev sib tsoo, nws yog ib qho tsim nyog yuav tsum tau txo qhov zawv zawg ntawm qhov sib tsoo nruab nrab thiab cov liner, yog li kev siv lub ntsiab yog los hloov cov duab ntawm lub liner ua hauj lwm saum npoo thiab ua rau kom muaj kev sib tsoo. Kev sib txhuam coefficient ntawm cov liner thiab qhov sib tsoo nruab nrab. High manganese steel liner tau siv ua ntej, thiab tam sim no muaj roj hmab liner, sib nqus liner, angular kauv liner, thiab lwm yam. Cov kev hloov kho hauv ob sab phlu no tsis yog tsuas yog superior rau siab manganese steel hauv ob sab phlu hauv kev ua tau zoo, tab sis kuj tuaj yeem ua kom ntev lub neej kev pab cuam ntawm lub pob zeb. Kev sib tsoo kev ua tau zoo tuaj yeem txhim kho tau zoo los ntawm kev txhim kho lub xeev cov lus tsa suab, tig tus nqi, ntxiv thiab qhov loj ntawm lub pob steel, cov khoom qib thiab cov khoom siv hauv ob sab phlu zoo ntawm pob zeb.
