I-calcium carbonate iyinhlanganisela engeyona into ephilayo eyingxenye eyinhloko yedwala le-limestone (i-limestone ngamafuphi) kanye ne-calcite. I-calcium carbonate ihlukaniswe ngezigaba ezimbili: i-calcium carbonate esindayo kanye ne-calcium carbonate elula. Njengomkhiqizi wemishini yokukhiqiza i-calcium carbonate, i-HC, uchungechunge lwe-HCQ i-Raymond mill, uchungechunge lwe-HLM vertical mill, uchungechunge lwe-HLMX ultra-fine vertical mill, uchungechunge lwe-HCH ring roller mill olukhiqizwe yi-HCM Machinery luye lwasetshenziswa kabanzi ekukhiqizweni nasekucutshungulweni kwe-calcium carbonate. Namuhla,Imishini ye-HCMsizokwethula kuwe ubuchwepheshe bokucubungula kanye nemishini ye-calcium carbonate. Okokuqala, ubuchwepheshe bokucubungula nokukhiqiza i-calcium carbonate esindayo Njengamanje, kunezinqubo ezimbili eziyinhloko zokukhiqizwa kwezimboni kwe-calcium carbonate esindayo, enye inqubo eyomile; Enye indlela emanzi, ukukhiqizwa kwemikhiqizo eyomile, ingasetshenziswa kabanzi enjolobeni, epulasitikini, ezimbozweni nakwezinye izimboni. Inqubo emanzi isetshenziswa embonini yephepha, kanti umkhiqizo ojwayelekile uthengiswa ngesimo se-pulp kuma-paper mill. 1. Inqubo yokukhiqiza eyomile: Izinto Zokusetshenziswa → Ukususwa kwe-Gangue → I-Jaw Crusher → I-Impact hammer Crusher → I-Raymond Mill/i-ultrafine vertical mill → Uhlelo lokufaka amagredi → Ukupakisha → Umkhiqizo. Okokuqala, i-gangue isuswa ngesandla ngokukhetha i-calcite, i-limestone, i-chalk, ama-seashell, njll., athuthwa esuka e-quarry. Ngemuva kwalokho i-limestone ichotshozwa kakhulu yi-crusher, bese kuthi i-fine calcite powder ichotshozwe yi-Raymond (pendulum) grinding, bese kuthi ekugcineni i-grinding powder ibekwe ngamagredi yi-classifier, bese kuthi i-powder ehlangabezana nezidingo zosayizi wezinhlayiya ifakwe endaweni yokugcina njengomkhiqizo, ngaphandle kwalokho ibuyiselwa emshinini wokugaya ukuze igaywe futhi.
2, inqubo yokukhiqiza emanzi:
Itshe eliluhlaza → umhlathi ophukile → I-Raymond mill → I-wet mixing mill noma umshini wokuhlubula (ongenazikhawu, onezigaba eziningi noma umjikelezo) → I-Wet classifier 1 → ukuhlolwa → ukomisa → ukusebenza → Ukupakisha → Umkhiqizo.
Okokuqala, ukumiswa okwenziwe ngempuphu eyomile kuphinde kuchotshozwe emshinini wokugaya, futhi ngemva kokuphelelwa amanzi emzimbeni nokomisa, kulungiswa i-calcium carbonate esindayo enhle kakhulu. Izinqubo eziyinhloko zokugaya okumanzi i-calcium carbonate esindayo yilezi:
(1) Itshe elingavuthiwe → umhlathi ophukile → I-Raymond mill → umshini wokugaya omanzi noma umshini wokukhuhla (ongaguquki, onezigaba eziningi noma umjikelezo) → umshini wokuhlukanisa omanzi → ukuhlolwa → ukomisa → ukusebenza → ukufaka isikhwama (i-calcium esindayo yezinga lokumboza). Ukuhlukaniswa okumanzi okumnandi kwengezwa ekugelezeni kwenqubo, okungahlukanisa imikhiqizo efanelekile ngesikhathi futhi kuthuthukise ukusebenza kahle. Imishini yokuhlela emanzi okumnandi kakhulu ifaka phakathi i-cyclone encane enobubanzi, i-horizontal spiral classifier kanye ne-dish classifier, ukuhlushwa kwe-pulp ngemuva kokuhlukaniswa kuncane kakhulu, ngezinye izikhathi kudinga ukwengeza ithangi lokuthungwa. Inkomba yezomnotho yenqubo ilungile, kodwa ukuhlukaniswa kunzima ukusebenza, futhi ayikho imishini yokuhlela emanzi okumnandi kakhulu.
(2) Itshe eliluhlaza → ukuphuka komhlathi - I-Raymond mill → i-wet stir mill - ukuhluza → ukomisa -→ ukusebenza -→ ukufaka izikhwama (i-calcium esindayo yezinga lokupakisha).
(3) Itshe eliluhlaza → ukuphuka komhlathi → umshini wokugaya iRaymond → umshini wokugaya noma wokuxovula omanzi (ongenazikhawu, onezigaba eziningi noma umjikelezo) → ukuhlolwa (i-calcium slurry enzima ye-calcium slurry yephepha).
Okwesibili, ubuchwepheshe bokucubungula kanye nokukhiqiza i-calcium carbonate ekhanyayo Inqubo yokulungiselela i-calcium carbonate ekhanyayo: izinto zokusetshenziswa ze-limestone zihlukaniswa zibe usayizi othile, i-lime kiln ihlanganiswa futhi ishiswe ibe yi-lime (Ca0) kanye ne-flue gas (igesi ye-kiln equkethe i-carbon dioxide), i-lime ifakwa ku-digester eqhubekayo bese kufakwa amanzi ukuze kugaywe ukuze kutholakale i-Ca (OH)2 emulsion. Ngemva kokuhlunga nokucwenga okuqinile, i-Ca (OH) 2 fine emulsion ithunyelwa ku-carbonization reactor/carbonization tower kanye negesi ye-kiln ecwengisisiwe equkethe i-carbon dioxide ukuze kusebenze i-carbonization synthesis. Ngesikhathi esifanayo, inani elifanele lezithasiselo liyangezwa ukuze lisebenze ngaphansi kwezimo ezithile zobuchwepheshe ukuze kukhiqizwe i-calcium carbonate ecolekile kakhulu. I-Superfine calcium carbonate slurry yafakwa ku-coating reactor futhi i-quantitative coating agent yanezelwa ukuze isebenze ngaphansi kwezimo ezithile zobuchwepheshe ukuze kutholakale imikhiqizo ye-calcium carbonate esebenzayo ecolekile kakhulu ngokuguqulwa kwendawo. I-ultra-fine active calcium carbonate slurry iyahlungwa futhi ikhishwe amanzi, bese ithunyelwa ku-dryer ukuze kukhishwe amanzi ukuze kufinyelelwe impuphu eyomile edingekayo kokuqukethwe kwamanzi, bese ichotshozwa ukuze kufakwe umkhiqizo oqediwe.
Lokhu okungenhla yisingeniso sobuchwepheshe bokucubungula nokukhiqiza i-calcium carbonate. Uma ufuna ukwazi kabanzi ngobuchwepheshe bokucubungula nokukhiqiza i-calcium carbonate, sicela usinike umlayezo ukuze uthole imininingwane:hcmkt@hcmilling.com
