Calcium carbonate yog ib qho inorganic compound uas yog lub ntsiab Cheebtsam ntawm limestone pob zeb (limestone luv luv) thiab calcite. Calcium carbonate muab faib ua ob pawg: hnyav calcium carbonate thiab lub teeb calcium carbonate. Raws li lub chaw tsim khoom siv calcium carbonate, HC, HCQ series Raymond mill, HLM series ntsug mill, HLMX series ultra-fine ntsug mill, HCH series nplhaib roller mill tsim los ntawm HCM Machinery tau siv dav hauv kev tsim khoom thiab ua cov calcium carbonate. Niaj hnub no,Cov Tshuab HCMyuav qhia koj txog cov txheej txheem ua thiab cov khoom siv ntawm calcium carbonate. Ua ntej, cov txheej txheem ua calcium carbonate hnyav thiab tsim khoom Tam sim no, muaj ob txoj hauv kev tseem ceeb rau kev tsim khoom lag luam ntawm calcium carbonate hnyav, ib qho yog cov txheej txheem qhuav; Ib qho yog txoj kev ntub, kev tsim khoom qhuav, tuaj yeem siv dav hauv roj hmab, yas, txheej thiab lwm yam lag luam. Cov txheej txheem ntub yog siv hauv kev lag luam ntawv, thiab cov khoom dav dav yog muag hauv daim ntawv pulp rau cov chaw ua ntawv. 1. Cov txheej txheem tsim khoom qhuav: Cov Khoom Siv Raw → Tshem Tawm Gangue → Lub Tshuab Sib Tsoo Lub Qhov → Lub Tshuab Sib Tsoo Rauj → Lub Tshuab Sib Tsoo Rauj → Raymond Mill / ultrafine ntsug zeb → Kev Ntsuas Qib → Ntim → Khoom. Ua ntej, lub gangue raug tshem tawm los ntawm tes los ntawm kev xaiv calcite, limestone, chalk, seashells, thiab lwm yam, uas raug thauj los ntawm lub chaw txua zeb. Tom qab ntawd lub limestone raug tsoo los ntawm lub tshuab sib tsoo, thiab tom qab ntawd cov hmoov calcite zoo raug tsoo los ntawm Raymond (pendulum) sib tsoo, thiab thaum kawg cov hmoov sib tsoo raug ntsuas los ntawm lub tshuab faib tawm, thiab cov hmoov uas ua tau raws li qhov loj me me raug ntim rau hauv qhov chaw khaws cia ua khoom, txwv tsis pub nws raug xa rov qab mus rau lub tshuab sib tsoo kom sib tsoo dua.
2, cov txheej txheem tsim khoom ntub dej:
Cov hlau tsis zoo → lub puab tsaig tawg → lub tshuab Raymond → lub tshuab sib tov ntub lossis lub tshuab stripping (tsis tu ncua, ntau theem lossis voj voog) → Lub tshuab cais ntub 1 → kev tshuaj ntsuam → kev ziab → kev ua kom ua haujlwm → Ntim → Khoom.
Ua ntej, cov hmoov qhuav qhuav uas ua los ntawm cov hmoov zoo raug tsoo ntxiv rau hauv lub tshuab zeb, thiab tom qab lub cev qhuav dej thiab ziab, cov calcium carbonate hnyav zoo heev raug npaj. Cov txheej txheem tseem ceeb ntawm kev sib tsoo ntub calcium carbonate hnyav yog:
(1) Cov hlau tsis zoo → lub puab tsaig tawg → lub tshuab Raymond → lub tshuab sib xyaw ntub lossis lub tshuab tev tawv (tsis tu ncua, ntau theem lossis voj voog) → lub tshuab cais ntub → kev tshuaj ntsuam → kev ziab → kev ua kom qhuav → lub hnab (txheej txheem calcium hnyav). Kev faib tawm ntub superfine ntxiv rau cov txheej txheem ntws, uas tuaj yeem cais cov khoom tsim nyog raws sijhawm thiab txhim kho kev ua haujlwm. Cov khoom siv faib tawm ntub superfine feem ntau suav nrog lub voj voog me me, lub tshuab faib tawm kab rov tav thiab lub tais faib tawm, qhov concentration ntawm cov pulp tom qab kev faib tawm yog qhov nyias nyias, qee zaum yuav tsum ntxiv lub tank sedimentation. Cov ntsuas kev lag luam ntawm cov txheej txheem zoo, tab sis kev faib tawm nyuaj rau kev ua haujlwm, thiab tsis muaj cov khoom siv faib tawm ntub superfine zoo heev.
(2) Cov hlau nyoos → lub puab tsaig tawg - Raymond zeb → lub zeb sib xyaw ntub - sifting → ziab - → ua kom muaj zog - → hnab (ntim qib calcium hnyav).
(3) Cov hlau nyoos → lub puab tsaig tawg → Raymond zeb → lub tshuab sib xyaw ntub lossis lub tshuab tev tawv (tsis tu ncua, ntau theem lossis voj voog) → kev tshuaj ntsuam (cov calcium slurry hnyav).
Qhov thib ob, kev ua cov calcium carbonate thiab thev naus laus zis ntau lawm Cov txheej txheem npaj cov calcium carbonate sib zog: cov khoom siv limestone raw raug rhuav ua qhov loj me, lub kiln lime forging thiab hlawv rau hauv lime (Ca0) thiab flue gas (kiln gas uas muaj carbon dioxide), cov lime raug muab tso rau hauv lub digester tas mus li thiab dej raug ntxiv rau kev zom kom tau txais Ca (OH) 2 emulsion. Tom qab lim thiab ua kom zoo, Ca (OH) 2 emulsion zoo raug xa mus rau carbonization reactor / carbonization tower thiab mus rau hauv lub kiln roj refined uas muaj carbon dioxide rau carbonization synthesis reaction. Tib lub sijhawm, cov khoom ntxiv tsim nyog raug ntxiv rau kev cuam tshuam hauv qee qhov kev siv tshuab kom tsim cov calcium carbonate zoo heev. Superfine calcium carbonate slurry tau pub rau hauv lub reactor txheej thiab cov neeg sawv cev txheej ntau tau ntxiv rau kev cuam tshuam hauv qee qhov kev siv tshuab kom tau txais cov khoom calcium carbonate zoo heev nrog kev hloov kho qhov chaw. Cov ultra-fine calcium carbonate slurry raug lim thiab qhuav, thiab tom qab ntawd xa mus rau lub tshuab ziab kom ntxiv dewatering kom ncav cuag cov hmoov qhuav xav tau rau cov dej ntsiab lus, thiab tom qab ntawd crushed rau cov khoom tiav ntim.
Cov saum toj no yog cov txheej txheem ua thiab tsim cov calcium carbonate. Yog tias koj xav paub ntau ntxiv txog cov txheej txheem ua thiab tsim cov calcium carbonate, thov muab lus rau peb kom paub meej ntxiv:hcmkt@hcmilling.com
