CAs ua tej tsob nroj

Tus Maas cov kab ntau lawm yog cov tshuaj xis mas cov kab ntau lawm cov kab uas muaj ntawm cov khoom siv rau kev ua kom cov txiv maj mam ua. Nws tsuas yog muaj cov txheej txheem xws li crushing thiab pret profectionization, cement clinker hlawv, kev sib tsoo thiab ntim tau yooj yim.

Txheej txheem tsis
Nyob rau hauv cov txheej txheem ntawm cov kab ntau lawm, tsawg kawg yog 3 tons ntawm cov ntaub ntawv (suav nrog ntau cov ntaub ntawv raw, sib xyaw, gypsum) yuav tsum tau ua av rau txhua 1 tuj ntawm Portland cement ua. Raws li kev txheeb cais, lub zog noj ntawm cov kab ua kom qhuav ntau lawm kab ua haujlwm rau ntau tshaj li 30%, thee sib tsoo nyiaj rau kwv yees li 40%. Yog li no, kev xaiv tsim nyog ntawm kev sib tsoo khoom siv thiab cov txheej txheem ntws, kev ua haujlwm txaus, thiab tswj cov haujlwm tseem ceeb rau kev siv cov khoom lag luam zoo thiab txo kev siv hluav taws xob.

Txuj Ci Ntau Lawm
Cov txheej txheem ntau lawm ntawm Portland Maas yog tus sawv cev hauv cov yaum cov khoom siv ntau lawm. Nws tsuas yog siv limestone thiab av nplaum li cov ntaub ntawv nyoos, uas yog crushed, proportioned, thiab hauv av mus rau hauv cov ntaub ntawv nyoos. Tom qab ntawd, lawv tau muab pub rau hauv Caas li cas rau calcine cov ntaub ntawv, thiab lub clinker yog qhov haum ntawm gypsum (qee zaum sib xyaw nrog lwm cov ntaub ntawv lossis cov khoom sib ntxiv).

Cov khoom siv xis nyob suav nrog: Caas Teb Kiln, Cyclone Preheatre, grate txias
Cement Rotary Motary Main rau calcining Caas Clinker thiab tau siv dav hauv kev lag luam xws li MAFENT, Metallurgy, thiab tshuaj lom neeg engineering. Cov khoom siv muaj lub tog raj kheej, cov cuab yeej txhawb nqa, cov cuab yeej txhawb nqa nrog lub taub hau nres, ib lub taub hau sib tsoo, ib qho khoom siv ntawm lub taub hau, khoom siv sib txuas, thiab lwm yam. Lub Kiln Teb muaj cov yam ntxwv ntawm cov qauv yooj yim, kev ua haujlwm txhim khu kev qha, thiab kev tswj tau yooj yim ntawm cov txheej txheem ntau lawm.
Lub grate txias yog ib hom tshuab cua txias nrawm nrawm nrawm nrawm nrog lub ntsej muag txias dua rau ntawm lub phaj grate, ua rau lub clinker kub kom poob los ntawm 1200℃rau hauv qab 100 degree. Cov roj txias uas txias yog tom qab ntawd tso tawm rau hauv lub kiln li cov huab cua ob.

Ua Ntej Homogenization
(1) Kev sib tsoo: hauv cov txheej txheem ntawm cov hmoov av, feem ntau yog cov khoom nyoos, xws li limestone, av nplaum, hlau ore, thiab thee. Limestone yog cov khoom siv ntawm cov txiv neej loj tshaj plaws hauv Caas ntau lawm, nrog qhov loj dua me me thiab ua kom nruj dua tom qab kev txiav. Yog li ntawd, crushing ntawm limestone ua lub luag haujlwm tseem ceeb hauv cov khoom crushing hauv cov nroj tsuag xis.
(2) pre homogenization technology rau cov ntaub ntawv raw yog hais txog kev siv cov khoom siv raw thiab ua kom cov khoom siv raw thiab ua kom lub raw khoom cia
Raw Khoom Siv Khoom Siv Hauv Tsev
Hauv cov txheej txheem ntau lawm ntawm cov txheej txheem ua cov cua txias tshiab, thiab cov khoom siv ua haujlwm ntawm cov khoom sib xyaw ua ke ntawm cov khoom sib xyaw ntawm cov khoom raw nkag mus rau hauv lub qhov.
kev tua neeg
Tom qab cov khoom siv raw yog preheated thiab pre decomposed nyob rau hauv lub voj voog preheater, cov txheej txheem tom ntej yog kom nkag mus rau lub cub qeeb rau clinker hlawv. Nyob rau hauv lub cubn, carbonate txuas ntxiv decomposes sai sai thiab undergoes ib series ntawm cov khoom siv- cov zaub mov muaj xws li cov zaub mov hauv CAs Clinker. Raws li qhov ntsuas ntawm cov khoom siv nce, cov zaub mov yuav hloov mus ua cov kua dej, thiab cov yaj nyob hauv cov theem ua kua yuav ua rau muaj ntau cov clinker. Tom qab Clinker yog hlawv, qhov kub pib txo qis. Thaum kawg, qhov siab - kub clinker tawm ntawm qhov kub thiab txias uas muaj kev thauj mus los ntawm txoj kev thauj mus los hauv dej Nyob rau tib lub sijhawm, lub tswv yim kub ntawm lub siab- Qhov kub thiab txias clinker tau rov zoo los txhim kho lub ntsuas cua sov thiab clinker zoo ntawm cov kab ke.

Preheating decomposition
Preheating thiab ib feem decomposition ntawm raw cov ntaub ntawv ua tiav los ntawm preheaters, hloov qee yam haujlwm ntawm cov kiln luv, kom luv ntev ntawm lub kiln. Nyob rau tib lub sijhawm, cov roj khoom siv hluav taws xob sib pauv hauv lub xeev muaj kev sib xyaw ua ke, thiab ua tiav cov pa hluav taws xob kom nrawm nrawm nrawm nrawm nrawm nrawm nrawm
(1) Cov Khoom Siv Dispersion
80% ntawm kev sib pauv cua sov tshwm sim nyob rau hauv cov inlet pipeline. Cov khoom siv raw pub rau hauv lub pas dej Preheline yog defleed upward los ntawm lub siab- ceev nce kev Airflow thiab dispersed.
(2) roj -}} kev sib cais
Thaum lub Airflow nqa cov hmoov mus rau hauv kev kub nyhiab, nws tau txav mus rau qhov kawg ntawm lub khob hliav qab, thiab tom qab ntawd tig rov qab kom raug rho tawm los ntawm cov pa yeeb.
(3) pre decomposition
Qhov tshwm sim ntawm pre decomposition technology yog cov thev naus laus zis hauv cov txheej txheem hloov pauv. Nws cuam tshuam nrog kev txiav txim siab rauv ntawm lub preheater thiab txhim kho cov txheej txheem hluav taws xob kom sai, thiab txhim kho cov roj ntsha sab hauv kom nrawm rau hauv cov khoom nyoos rau hauv kiln mus rau ntau dua 90%. Txav mus rau cov carbonate decomposition ua hauj lwm uas yog Ameslikas ua nyob rau hauv lub cau lub cub rau cov decomposition rauv; Feem ntau ntawm cov roj txuas ntxiv los ntawm cov decomposition rauv, nrog tus nqi me me ntawm lub taub hau cais, thiab yog conducive rau loj {3} nplai ntau lawm; Vim yog cov khaub ncaws sib xyaw roj thiab cov khoom siv raw, cov khoom siv hluav taws xob kub, hloov kho cov txheej txheem kub, thiab carbonate decompposition cov txheej txheem. Yog li ntawd, nws muaj cov kev ua tau zoo thiab cov yam ntxwv zoo xws li muaj txiaj ntsig zoo, ua haujlwm siab, thiab kev noj tsawg.

Maas Sib Tsoo
Kev sib tsoo MAAs yog cov txheej txheem kawg hauv kev txhim kho cov cement thiab tseem muaj zog siv cov txheej txheem ntau tshaj plaws. Nws lub luag haujlwm tseem ceeb yog kom zom cov cementy, thiab lwm yam kev ua tau zoo, thiab ua kom muaj kev ua tiav ntawm txoj cai ntawm cov xis thiab ua kom tawv nqaij.
Ncua Tawv Ntim
Maas tuaj yeem xa tawm hauv ob txoj kev: bagged thiab loj. Tus qauv hauv lub teb chaws yuav tsum tau hais tias qhov sib npaug ntawm cov xis kawm yuav tsum ncav cuag 70% lossis ntau dua, thiab ntau dua, thiab kev txhim kho loj hauv Suav teb.

Cim npe nrov: CEMENT YUAV UA TSOB NROJ, CHRIVE MAAs siv cov nroj tsuag tsob nroj, cov chaw muag khoom, Hoobkas
