Calcium carbonate yog ib qho inorganic compound uas yog lub ntsiab ntawm limestone pob zeb (limestone luv luv) thiab calcite.Calcium carbonate tau muab faib ua ob pawg: hnyav calcium carbonate thiab lub teeb calcium carbonate.Raws li cov khoom siv calcium carbonate ntau lawm, HC, HCQ series Raymond zeb, HLM series ntsug zeb, HLMX series ultra-fine ntsug zeb, HCH series nplhaib cov menyuam zeb ua los ntawm HCM Machinery tau siv dav hauv kev tsim thiab ua cov calcium carbonate.Hnub no,HCM Machineryyuav qhia koj txog kev siv tshuab thiab khoom siv ntawm calcium carbonate.Ua ntej, hnyav calcium carbonate ua thiab cov cuab yeej siv ntau lawm Tam sim no, muaj ob txoj haujlwm tseem ceeb rau kev tsim cov calcium carbonate hnyav, ib qho yog cov txheej txheem qhuav;Ib qho yog txoj kev ntub dej, qhuav qhuav ntawm cov khoom, tuaj yeem siv dav hauv roj hmab, plastics, coatings thiab lwm yam lag luam.Cov txheej txheem ntub dej yog siv hauv kev lag luam ntawv, thiab cov khoom siv dav dav yog muag hauv daim ntawv pulp rau ntawv mills.1. Cov txheej txheem qhuav qhuav: Cov Khoom Raw → Gangue tshem tawm → Lub puab tsaig Crusher → Impact rauj Crusher → Raymond Mill / ultrafine ntsug zeb → Qib system → Ntim → khoom.Ua ntej, lub gangue raug tshem tawm ntawm tes los ntawm kev xaiv calcite, limestone, chalk, seashells, thiab lwm yam, uas yog thauj los ntawm cov chaw txua txiag zeb.Tom qab ntawd cov limestone yog ntxhib crushed los ntawm crusher, thiab tom qab ntawd cov hmoov calcite zoo yog crushed los ntawm Raymond (pendulum) sib tsoo, thiab thaum kawg cov hmoov sib tsoo tau muab qhab nia los ntawm cov chav kawm, thiab cov hmoov uas ua tau raws li qhov xav tau ntawm cov khoom loj yog ntim rau hauv qhov chaw cia. raws li cov khoom lag luam, txwv tsis pub nws rov qab mus rau lub tshuab sib tsoo kom rov ua dua.
2, ntub ntau lawm txheej txheem:
Raw ore → tawg lub puab tsaig → Raymond zeb → ntub sib tov zeb los yog stripping tshuab (intermittent, multi-theem los yog voj voog) → ntub classifier 1 → tshuaj ntsuam → ziab → ua kom → ntim → khoom.
Ua ntej, qhov raug tshem tawm ua los ntawm cov hmoov zoo qhuav yog ntxiv rau hauv lub zeb, thiab tom qab lub cev qhuav dej thiab ziab, super-nplua hnyav calcium carbonate yog npaj.Cov txheej txheem tseem ceeb ntawm ntub sib tsoo hnyav calcium carbonate yog:
(1) Raw ore → tawg lub puab tsaig → Raymond zeb → ntub dej nplawm zeb los yog tev tshuab (nruab nrab, ntau theem lossis lub voj voog) → ntub dej cais → tshuaj ntsuam → ziab → ua kom → bagging (txheej qib hnyav calcium).Kev faib cov ntub dej superfine yog ntxiv rau cov txheej txheem ntws, uas tuaj yeem cais cov khoom tsim nyog hauv lub sijhawm thiab txhim kho kev ua haujlwm.Cov khoom siv ntub dej superfine faib feem ntau suav nrog me me txoj kab uas hla cyclone, kab rov tav kauv classifier thiab phaj classifier, qhov concentration ntawm pulp tom qab kev faib tawm yog nyias nyias, qee zaum yuav tsum tau ntxiv sedimentation tank.Kev lag luam kev lag luam ntawm cov txheej txheem yog qhov zoo, tab sis kev faib tawm yog qhov nyuaj rau kev khiav lag luam, thiab tsis muaj cov khoom siv sib cais ntub dej superfine zoo heev.
(2) Raw ore → puab tsaig tawg - Raymond zeb → ntub nplawm zeb - sifting → ziab - → ua kom - → bagging (packing qib hnyav calcium).
(3) Raw ore → puab tsaig tawg → Raymond zeb → ntub nplawm zeb los yog tev tshuab (nruab nrab, ntau theem lossis lub voj voog) → kev tshuaj ntsuam (cov ntawv txheej qib hnyav calcium slurry).
Thib ob, lub teeb calcium carbonate ua thiab cov tshuab tsim khoom Kev npaj cov txheej txheem ntawm lub teeb calcium carbonate: limestone raw khoom tawg mus rau hauv ib qho loj, txiv qaub kiln forging thiab firing rau hauv txiv qaub (Ca0) thiab flue gas (kiln gas uas muaj carbon dioxide), cov txiv qaub yog muab tso rau hauv lub digester tas mus li thiab dej ntxiv rau kev zom kom tau Ca (OH) 2 emulsion.Tom qab ntxhib pom thiab ua kom zoo, Ca (OH) 2 zoo emulsion raug xa mus rau carbonization reactor / carbonization ntauwd thiab mus rau hauv cov roj refined kiln uas muaj cov pa roj carbon dioxide rau carbonization synthesis cov tshuaj tiv thaiv.Nyob rau tib lub sijhawm, qhov tsim nyog tus nqi ntawm cov tshuaj ntxiv tau ntxiv los ua raws li qee yam kev siv tshuab los tsim cov calcium carbonate ultra-fine.Superfine calcium carbonate slurry tau muab tso rau hauv cov txheej txheej reactor thiab cov txheej txheem ntau ntxiv tau ntxiv rau cov tshuaj tiv thaiv nyob rau hauv qee yam kev siv tshuab kom tau txais cov khoom siv calcium carbonate superfine nrog kev hloov kho saum npoo.Lub ultra-fine active calcium carbonate slurry yog lim thiab lub cev qhuav dej, thiab ces xa mus rau lub tshuab ziab khaub ncaws ntxiv dewatering kom ncav cuag cov hmoov qhuav uas yuav tsum tau rau cov ntsiab lus dej, thiab ces crushed rau cov khoom tiav ntim.
Cov saum toj no yog cov txheej txheem calcium carbonate thiab ntau lawm technology qhia.Yog tias koj xav paub ntau ntxiv txog cov txheej txheem calcium carbonate thiab cov cuab yeej tsim khoom, thov muab lus rau peb kom paub meej:hcmkt@hcmilling.com
