I-Kaolin, ikakhulukazi i-ultra-fine calcined kaolin, njengento ebaluleke kakhulu ye-inorganic non-metallic, ibilokhu idlala indima ebaluleke kakhulu embonini yephepha ngezinto zayo ezibonakalayo ezinhle kakhulu.I-kaolin ebaliwe esetshenziswa embonini yephepha iyizimbotshana ezimbotshana futhi ezimhlophe eziphakeme ezisebenzayo, ezisetshenziswa kakhulu ukufaka esikhundleni se-titanium dioxide ebizayo nezinye izingulube zebanga eliphezulu.Njengomkhiqizi wemishini yokugaya, icalcined kaolinultra-fine mporollerisigayo ekhiqizwa HCMilling(Guilin Hongcheng) iye yasetshenziswa kabanzi futhi waqaphela ekukhiqizeni kaolin calcined.Okulandelayo yisingeniso sendlela yokukhiqiza i-kaolin ene-calcined:

Izidingo zekhwalithi zemboni yephepha ye-kaolin e-calcined ziboniswa ikakhulukazi ezidingweni zosayizi wezinhlayiyana, ubumhlophe, amandla okufihla, ukumuncwa kukawoyela, ukugxila kwe-viscosity, inani le-pH, inani lokugqoka kanye nezinye izinkomba ze-kaolin e-calcined.Ngaphansi kwezimo lapho imakethe ye-kaolin evamile ewashiwe ibilokhu incipha unyaka nonyaka ngenxa yomthelela we-calcium carbonate esindayo, ukuthengiswa kwemakethe kuye kwanda, okwenze abakhiqizi abaningi balandela okufanayo.Kusukela ngeminyaka yawo-1980, kutholwe inani elikhulu lochungechunge lwamalahle lwe-kaolin (kuthiwa lezi zindawo ezigciniwe zingaphezu kwamathani ayizigidi eziyizinkulungwane eziyi-10).Ngenxa yekhwalithi yayo ephezulu kanye nokungcola okumbalwa okuyingozi, uchungechunge lwamalahle i-kaolin isiphenduke impahla eluhlaza ekahle ekukhiqizeni ibanga le-kaolin elicolisekileyo lephepha.Ithemba lemakethe le-kaolin e-calcined ekhiqizwa ochungechungeni lwamalahle libanzi.

Inqubo yokukhiqiza kaolin calcined ikakhulukazi ihlanganisa izingxenye ezimbili: ukuchotshozwa superfine inqubo kanye calcining inqubo mhlophe.

1. Ukugaya inqubo ecoke kakhulu yendlela yokukhiqiza i-kaolin ehlanganisiwe: inqubo yokugaya i-superfine iyisixhumanisi esibalulekile sokunquma ikhwalithi ye-kaolin.Ukuchotshozwa kochungechunge lwamalahle i-kaolin superfine iyi-kaolin eqinile (kusuka ku-5~20mm ukuya ku-40~80 μ m) I-Ultrafine (kusuka ku-40 kuya ku-80 μ M ukuya ku-10 μ M noma - 2 μ m).calcined kaolinI-Raymond Mill kanye ne-calcined kaolin roller roller mill ekhiqizwa yi-HCMilling(Guilin Hongcheng) imishini yokuchoboza emahhadla, engasetshenziselwa ukuchotshozwa okumahhadla kwendlela yokukhiqiza i-kaolin e-calcined, futhi ingacubungula i-kaolin yochungechunge lwamalahle angama-80-600;HLMX uchungechunge calcined kaolin ultra-fine mporollerisigayo, isigayo se-ring roller kanye nezinye izinto zokusebenza zokuchoboza ze-ultra-fine zifanele ukuchotshozwa kwe-ultra-fine endleleni yokukhiqiza ye-kaolin e-calcined, engacubungula i-3-45 μ M i-superfine kaolin powder iyisigayo esihle se-kaolin esine-superfine powder.

2. Inqubo yokubala kanye nokwenza mhlophe kwendlela yokukhiqiza i-kaolin e-calcined: Ngokubuka izici ze-diagenetic zochungechunge lwamalahle i-kaolin, okungukuthi, iqukethe izinto eziphilayo, ukuze ubumhlophe bayo be-ore eluhlaza bube ngu-6 ~ 40% kuphela, okukude kakhulu. ukuhlangabezana nezidingo zekhwalithi yemboni yephepha ye-kaolin eboshwe, ngakho-ke inqubo yokukhipha uketshezi nokuba mhlophe kufanele yamukelwe.Ngokwezidingo ezihlukene zekhwalithi ye-kaolin, ingabuye ihlukaniswe ibe yimikhiqizo emibili: izinga lokushisa eliphakathi ne-calcined kaolin kanye nokushisa okuphezulu kwe-kaolin e-calcined.

Ukuqhathaniswa kwenqubo yezindlela zokukhiqiza i-kaolin e-calcined: ngokuya ngokuthi inqubo ye-superfine iyinqubo emanzi noma inqubo eyomile kanye nokulandelana kwenqubo ye-superfine kanye nenqubo yokubala, izinqubo zokukhiqiza ezine zingahlanganiswa, okungukuthi.

(1) inqubo ye-superfine emanzi elandelwa inqubo yokubala (2) inqubo eyomile ye-superfine elandelwa inqubo yokubala (3) ukubala okulandelwa inqubo ye-superfine emanzi (4) ukubala okulandelwa inqubo eyomile ye-superfine.Ngenxa yokuthi abantu banokuqonda okuhlukile kwezinto zokwakha ezinhle kakhulu, izindlela zenqubo ezisetshenziswa emabhizinisini ahlukene zihlukile:

(1) Inqubo yokubala emanzi kakhulu yinde uma kuqhathaniswa, kodwa inokuvumelana nezimo eziqinile ezintweni ezingavuthiwe, futhi ikhwalithi yomkhiqizo ingahlangabezana nezidingo zemboni yephepha;

(2) Inqubo yokubala kanye nokumanzisa kabusha okucolekile ngokuvamile kudinga okomisa okokusebenza okukhethekile kanye nezisetshenziswa zokusabalalisa.Le nqubo inokuguquguquka okubuthakathaka ezintweni ezingavuthiwe, kodwa ingakhiqiza imikhiqizo edingwa yimboni yephepha;

(3) Inqubo eyomile kakhulu yokubala kanye nokubala kokuqala kanye nenqubo eyomile ecwebezelayo ayikwazi ukukhiqiza i-kaolin embonini yephepha (ngenxa yesizathu semishini esezingeni eliphakeme), edinga izinga eliphezulu lezinto zokusetshenziswa.

Sekukonke, inqubo ye-superfine eyomile ngaphambi kokubala iyasebenza kakhulu, futhi umdwebo wokugeleza kwenqubo uthi: insimbi eluhlaza → ukuchotshozwa → ukuchotshozwa → okucolekileyo kakhulu → ukubala → umkhiqizo.Izinzuzo zale nqubo yilezi: (1) inqubo ifushane, futhi yonke le nqubo idinga kuphela izinto ezintathu kuya kwezine eziyinhloko.Uma HongchengI-HLMX calcined kaolin ultrafine powder mill ikhethiwe, imishini emithathu kuphela edingekayo, okungukuthi, i-crusher, i-calcined kaolin ultrafine powder mill, i-calciner, elungele ukuphathwa okuphelele nokuhlela okunengqondo;(2) Ukusetshenziswa kwamandla kunengqondo.Kule nqubo, inqubo ye-superfine yezinto ibekwe ngaphambi kwenqubo yokubala ukugwema inkinga yokusebenzisa amandla amaningi ngenxa yokuchotshozwa nokushiswa kwezinto.Uma inqubo yokubala impushana yamukelwa, ingathathwa njengenqubo egcwele yokukhiqiza eyomile.Mayelana nobuchwepheshe, ukusetshenziswa kwamandla kunengqondo.

Ukusebenzisa uchungechunge lwamalahle i-kaolin ukukhiqiza i-kaolin ebaliwe yezinga lokunamathela embonini yephepha ngokungangabazeki kuyindlela ephumelelayo yokusebenzisa ngokunengqondo i-ganggue yamalahle.Kumele kuqashelwe ukuthi izindlela ezifanele zenqubo kufanele zikhethwe ngokuya ngezinsiza zendawo kanye nemali.Uma ufuna ukwazi okwengeziwe mayelana nezindlela zokukhiqiza nokukhethwa kwemishini ye-kaolin e-calcined, sicela usishayele ukuze uthole imininingwane.
