I-Calcium carbonate iyinhlanganisela ye-inorganic eyingxenye eyinhloko yetshe le-limestone (i-limestone ngamafuphi) kanye ne-calcite.I-calcium carbonate ihlukaniswe izigaba ezimbili: i-heavy calcium carbonate ne-light calcium carbonate.Njengomkhiqizi wemishini yokukhiqiza ye-calcium carbonate, i-HC, uchungechunge lwe-HCQ u-Raymond mill, uchungechunge lwe-HLM uchungechunge oluqondile lokugaya, uchungechunge lwe-HLMX oluqondile oluqondile oluqondile, i-HCH series ring roller mill ekhiqizwe yi-HCM Machinery isetshenziswe kabanzi ekukhiqizeni nasekusetshenzisweni kwe-calcium carbonate.Namuhla,Imishini ye-HCMizokwethula ubuchwepheshe bokucubungula kanye nemishini ye-calcium carbonate.Okokuqala, ukucutshungulwa kwe-calcium carbonate esindayo nobuchwepheshe bokukhiqiza Njengamanje, kunezinqubo ezimbili eziyinhloko zokukhiqizwa kwezimboni ze-calcium carbonate esindayo, enye inqubo eyomile;Enye indlela emanzi, ukukhiqizwa okomile kwemikhiqizo, ingasetshenziswa kabanzi ku-raber, amapulasitiki, ama-coatings nezinye izimboni.Inqubo emanzi isetshenziswa embonini yephepha, futhi umkhiqizo ojwayelekile uthengiswa ngesimo se-pulp kuma-mill paper.1. Inqubo yokukhiqiza eyomile: Izinto ezisetshenziswayo → Ukususwa kwe-Gangue → I-Gaw Crusher → I-Impact Hammer Crusher → I-Raymond Mill/i-ultrafine mpo yokugaya → Isistimu yokugreda → Ukupakisha → Umkhiqizo.Okokuqala, i-ganggue isuswa ngesandla ngokukhetha i-calcite, i-limestone, ushoki, amagobolondo olwandle, njll., ezithuthwa enkwalini.Khona-ke i-limestone igaywe ngokuchotshozwa yi-crusher, bese i-calcite powder ecolisekileyo ichotshozwa u-Raymond (pendulum) ukugaya, futhi ekugcineni impushana yokugaya ihlelwa yi-classifier, bese impushana ehlangabezana nezidingo zesayizi yezinhlayiya ipakishwe endaweni yokugcina. njengomkhiqizo, ngaphandle kwalokho ubuyiselwa emshinini wokugaya ukuze ugaye futhi.
2, inqubo yokukhiqiza emanzi:
Insimbi eluhlaza → umhlathi ophukile → Ugayo lukaRaymond → umshini wokuxuba omanzi noma umshini wokuhlubula (izikhawu, izigaba eziningi noma umjikelezo)→ Isigaba esimanzi 1 → ukuhlola → ukomisa → ukwenza kusebenze → Ukupakisha → Umkhiqizo.
Okokuqala, ukumiswa okwenziwe ngempushana ecolekileyo eyomile kuphinde kuchotshozwe esigayweni, futhi ngemva kokuphelelwa amanzi emzimbeni nokomiswa, kulungiswa i-super-fine heavy calcium carbonate.Izinqubo eziyinhloko zokugaya okumanzi kwe-calcium carbonate yilezi:
(1) Itshe lensimbi eluhlaza → umhlathi ophukile → Ugayo lukaRaymond → umshini wokugaya omanzi noma umshini wokuxebula (izikhawu, izigaba eziningi noma umjikelezo)→ isigaba esimanzi → ukuhlola → ukomisa → ukwenza kusebenze → isikhwama (ukumboza ibanga le-calcium esindayo).Ukuhlukaniswa kwe-superfine okumanzi kwengezwa ekugelezeni kwenqubo, okungahlukanisa imikhiqizo efanelekayo ngesikhathi futhi kuthuthukise ukusebenza kahle.Imishini yokuhlukanisa i-superfine emanzi ngokuyinhloko ihlanganisa isivunguvungu esinobubanzi obuncane, isigaba esivundlile esivundlile kanye nesihlukanisi sesitsha, ukugxiliswa kwe-pulp ngemva kokuhlukaniswa kuncane kakhulu, ngezinye izikhathi kuyadingeka ukwengeza ithangi le-sedimentation.Inkomba yezomnotho yenqubo yinhle, kodwa ukuhlukanisa kunzima ukusebenza, futhi azikho izinto zokusebenza ezisebenza kahle kakhulu zokuhlukanisa ze-superfine.
(2) Insimbi eluhlaza → ukuphuka kwemihlathi - Igayo likaRaymond → isigayo esinyakazayo esimanzi - ukusefa → ukomisa -→ ukwenza kusebenze -→ ukupakisha (ukupakisha ibanga le-calcium esindayo).
(3) Insimbi eluhlaza → ukuphuka kwemihlathi → Isigayo sikaRaymond → isigayo esinyakazayo esimanzi noma umshini wokucwecwa (izikhawu, izigaba eziningi noma umjikelezo)→ ukuhlola (ibanga lokumboza ngephepha i-calcium slurry esindayo).
Okwesibili, ukukhanya kwe-calcium carbonate processing kanye nobuchwepheshe bokukhiqiza Inqubo yokulungiselela ukukhanya kwe-calcium carbonate: impahla eluhlaza ye-limestone iphulwa ibe usayizi othize, i-lime holn igaya futhi idutshulwe ibe umcako (Ca0) kanye negesi ye-flue (igesi yomlilo equkethe i-carbon dioxide), umcako kufakwa ku-digester eqhubekayo futhi amanzi anezelwa ukuze kugaywe ukuze kutholwe i-Ca (OH)2 emulsion.Ngemva kokuhlunga okumahhadla nokucwengisiswa, i-emulsion ye-Ca (OH) 2 ecolekileyo ithunyelwa kumbhoshongo we-carbonization reactor/carbonization kanye negesi yomlilo ecolisisiwe equkethe i-carbon dioxide yokusabela kwe-carbonization synthesis.Ngesikhathi esifanayo, inani elifanele lezithasiselo liyengezwa ukuze kusabele ngaphansi kwezimo ezithile zobuchwepheshe ukukhiqiza i-ultra-fine calcium carbonate.I-Superfine calcium carbonate slurry yafakwa kureactor enamathelayo futhi i-ejenti yokumboza yobuningi yengezwa ukuze kusabeleke ngaphansi kwezimo ezithile zobuchwepheshe ukuze kutholwe imikhiqizo ye-calcium carbonate esebenza kahle kakhulu enokuguqulwa kwendawo.I-ultra-fine active calcium carbonate slurry iyahlungwa futhi iphelelwe amanzi, bese ithunyelwa ukomisa ukuze iqhubeke nokukhipha amanzi ukuze ifinyelele impushana eyomile edingekayo kokuqukethwe kwamanzi, bese igaywa ukuze kuhlanganiswe umkhiqizo oqediwe.
Okungenhla isingeniso se-calcium carbonate processing and production technology.Uma ufuna ukwazi okwengeziwe mayelana ne-calcium carbonate processing kanye nobuchwepheshe bokukhiqiza, sicela usinikeze umlayezo ngemininingwane:hcmkt@hcmilling.com
