Kunezinhlobo eziningi zemishini yokugaya nokucubungula i-calcium esindayo eShayina. Ngokuvamile, ingafinyelela umphumela wokukhiqizwa okuhle kakhulu ngokuhlanganisa ne-classifier enhle kakhulu ukwakha uhlelo lokucubungula oluhle kakhulu. Kodwa-ke, iyiphi inqubo yokukhiqiza nemishini enengqondo kakhulu edinga ukuhlola ngobuqotho izinqubo nemishini ehlukahlukene ngokuya ngezidingo zobukhulu bemakethe kanye nenzuzo ephezulu yebhizinisi. Bese-ke, ungayikhetha kanjani umugqa wokukhiqiza inqubo eyomile ye-calcium esindayo? HCMilling (Guilin Hongcheng), njengomkhiqizi weumshini wokugaya i-calcium osindayoimishini, yethulwa ngezansi mayelana nokuqhathaniswa kwezinqubo zokukhiqiza ezomile ze-calcium carbonate esindayo:

I-calcium carbonate enamandla umshini wokugaya oqondile oqondile omuhle kakhulu

Njengamanje, isidingo esikhulu emakethe ye-calcium esindayo yaseShayina singama-meshes angu-600 ~ 1500 emikhiqizo ye-calcium esindayo; Izinga lokwenyuka kwenani elengeziwe lemikhiqizo ye-calcium esindayo liphansi (uma kuqhathaniswa ne-talc, i-barite, i-kaolin, njll.), futhi isikali singenye yezinto eziyinhloko ezithinta izinzuzo. Ukuze kuhlangatshezwane nezidingo zemakethe kanye nenzuzo yebhizinisi, ubuchwepheshe bokucubungula kanye nemishini ye-calcium esindayo kufanele kukhethwe ngokomthetho: ubuchwepheshe obuvuthiwe, ukusebenza kwemishini okuthembekile, ikhwalithi yomkhiqizo ozinzile, ukutshalwa kwezimali okuncane ngethani lomkhiqizo, kanye nokusetshenziswa kwamandla aphansi. Ungayikhetha kanjani intambo yokukhiqiza inqubo eyomile ye-calcium esindayo? Imishini yokucubungula eyomile ye-calcium esindayo yakhiwe kakhulu ngemishini yokugaya nokulinganisa. Imishini yokugaya evuthiwe ifaka phakathi i-calcium carbonate esindayo i-Raymond mill, i-vibration mill, i-calcium carbonate ultra-fine ring roller mill, i-dry stirging mill,umshini wokugaya oqondile we-calcium carbonate osindayokanye ne-ball mill. Imishini yokuhlukanisa ngokuyinhloko iyi-impeller type superfine classifier eyenziwe ngesimiso se-forced eddy current. Okulandelayo ukuqhathanisa inqubo yokukhiqiza eyomile ye-calcium carbonate esindayo ngokusekelwe ezicini zobuchwepheshe zemishini yokugaya:

(1) inqubo yokuhlukanisa i-calcium carbonate esindayo I-Raymond mill+classifier ye-calcium carbonate esindayo. I-Raymond mill ingeye-rolling and crush. Injini iqhuba i-grinding roller, futhi amandla e-centrifugal asetshenziselwa ukuphoqa izinto ukuthi zicindezele, zishayisane futhi zichebe ngesivinini esiphansi, okuhambisana nokuchoboza okuphazamisayo ngezikhathi ezithile. I-Raymond mill inezinzuzo ezinkulu maqondana nokutshalwa kwezimali kanye nokusetshenziswa kwamandla lapho kukhiqizwa imikhiqizo engaphansi kwama-meshes angu-400. Kodwa-ke, isimiso sokugoqa nokuchoboza sinquma ukuthi inani lempuphu ecolekile ekhiqizwa yi-Raymond mill lincane kakhulu. Isibonelo, phakathi kwempuphu ecolekile engu-400 mesh, impuphu ecolekile engu-<10 m ibiza cishe u-36% we-g1 kuphela]. Ngokuvamile, i-Raymond mill ingashintshwa noma uhlelo lokulinganisa olucolekile kakhulu lungangezwa ukukhiqiza imikhiqizo ecolekile kakhulu engu-800 ~ 1250 meshes. Kodwa-ke, ngenxa yokuqukethwe okuphansi kwempuphu encane, amandla okukhiqiza i-superfine heavy calcium powder engaphezu kwama-meshes angu-800 nge-Raymond mill lincane kakhulu.

(2) Inqubo yokuxuba umshini wokomisa + inqubo yokuhlukanisa. Umshini wokugaya owomisayo waziwa nangokuthi umshini wokugaya ibhola. Umzimba wokugaya uyi-cylinder eqondile, enomgodi wokugaya phakathi, futhi izinto zezilwane kanye nendawo kujikeleziswa ukuze kukhiqizwe ukugaya. Ukusebenza kahle kokugaya kwayo kuphezulu, futhi ingasetshenziswa kanye nomshini wokuhlukanisa, ofaneleka kakhulu ekukhiqizweni kwe-calcium esindayo enhle kakhulu ngaphezu kwe-mesh engu-1250; Kodwa-ke, ngenxa yenani elikhulu lokuxhumana phakathi kwezinto nezinto zokugaya, ukungcola kokungcola kukhulu futhi umphumela wokuvikela imvelo mubi.

(3) Inqubo yokugaya ngokudlidliza + yokuhlukanisa. I-vibration mill iwukusebenzisa ukudlidliza okuvama kakhulu ukwenza umthelela omkhulu nokugaya phakathi kokugaya okuphakathi nezinto zokwakha, ukuze kuchotshozwe izinto zokwakha. I-vibration mill inokusebenza kahle kokugaya okuphezulu kanye nokuqukethwe okuphezulu kwempuphu ecolekileyo empuphu, okufanelekela kakhulu imikhiqizo yokugaya enosayizi we-mesh ongaphezu kuka-1250; Isilinganiso sobubanzi bobude be-vibration mill sikhulu, futhi into yokugaya ngokweqile iyingozi. Akuyona inketho enhle yokukhiqizwa kwe-calcium esindayo.

(4) Inqubo yokugaya indandatho ye-superfine calcium carbonate + inqubo yokuhlukanisa. Isakhiwo somshini kanye nendlela yokugaya ye-ring roller mill kufana nokwe-Raymond mill. Zombili zingaphansi kwengcindezi ye-centrifugal ye-grinding roller ukuze zondle izinto futhi zichotshozwe. Kodwa-ke, isakhiwo se-grinding roller sithuthukiswe kakhulu. Ukusebenza kahle kwayo kokuchoboza kungcono kakhulu kunokwe-Raymond mill, futhi zisetshenziswa kakhulu ukukhiqiza i-superfine heavy calcium ngaphansi kwama-meshes angu-1500. Njengamanje, lolu hlobo lwemishini yokugaya luye lwakhuthazwa ngokushesha embonini ye-calcium esindayo ngenxa yokonga amandla kanye nokutshalwa kwezimali okuphansi. Isibonelo, i-HCH1395 ring roller mill iqinisekiswe yi-China Calcium Carbonate Association njengemishini yokonga amandla nokunciphisa ukusetshenziswa emkhakheni wokucubungula i-superfine calcium carbonate eShayina.

(5) Inqubo yokugaya i-roller mill eqondile ye-calcium carbonate + inqubo yokuhlukanisa. Indlela yokugaya ye-roller mill eqondile (ebizwa ngokuthi i-roller mill eqondile ngamafuphi) ifana neye-Raymond mill, eqondene nokugoqa nokuchoboza. Njengoba ingcindezi ye-roller isetshenziswa ngendlela ye-hydraulic enomfutho ophezulu, ingcindezi ye-roller ezintweni iyanda ngamashumi noma ngaphezulu, ngakho-ke ukusebenza kwayo kahle kokuchoboza kungcono kakhulu kune-Raymond mill. Njengamanje, ingenye yemishini eyinhloko yokukhiqizwa okukhulu kwe-calcium esindayo. I-HLMX series super-fine vertical roller mill eyenziwe yi-HCMilling (Guilin Hongcheng) ngokusekelwe ku-roller mill evamile eqondile ingahlukanisa izinhlayiya ezincane zezinto ezigayiwe nge-roller mill eqondile, futhi ububanzi bokuhlukaniswa bungu-3um kuya ku-45um. Ingakwazi ukukhiqiza imikhiqizo yemininingwane ehlukene nge-roller mill eyodwa eqondile, futhi ingakhiqiza ngokushesha nangokuzinzile imikhiqizo yobuncane obufanayo. Uhlelo lokuhlukaniswa komoya lwesibili lulungiselelwe, olusebenza kahle kakhulu ekuhlukaniseni, lungahlukanisa ngempumelelo i-coarse powder kanye ne-fine powder, futhi ubuncane bokuhlukaniswa bungafika ku-3 μ m. Thola imikhiqizo efanelekile enezincazelo ezahlukene. Isetshenziswa kabanzi ekucubungulweni kwamaminerali angewona awensimbi njenge-calcite, i-barite, i-talc kanye ne-kaolin. Uma sibheka ukukhiqizwa kwempuphu ye-calcium carbonate njengesibonelo, ingakhiqiza imikhiqizo ye-mesh engu-325-3000, efanelekile kakhulu emikhiqizweni ye-mesh engu-800-2500, enesilinganiso sokukhiqiza seyunithi eyodwa esingu-4-40t/h. Yamukelwa kabanzi ngamabhizinisi asekhaya angaphezu kosayizi oqokiwe kanye nezinkampani ezidumile zempuphu eYurophu naseMelika.

(6) Inqubo yokugaya ibhola + ukuhlukanisa. Umgomo wokuchoboza wesigayo sebhola ukuthi izinto zokwakha kanye nemidiya yokugaya kuyathintana futhi kuyagaywa enqubweni yokujikeleza kwesigayo sebhola. Ukukhishwa kwayo kwempuphu ecolekile kuphansi kunokwemikhiqizo egaywe isigayo esomile nesigayo sokudlidliza, kodwa amandla ayo okucubungula aphezulu kunokweminye imishini yokucubungula, efanelekile emabhizinisini amakhulu okucubungula. Kodwa-ke, ukusetshenziswa kwamandla kwemikhiqizo enobunono kanye nomthamo ofanayo kuphakeme kakhulu kunokwesistimu yesigayo esijikelezayo esiqondile. Inzuzo yayo ukuthi ukuma kwezinhlayiya zomkhiqizo kuseduze nokuyindilinga, futhi imboni edinga ukuma kwezinhlayiya inenzuzo ezinye izinqubo ezingenakukwazi ukuyifanisa.

Njengamanje, kunabakhiqizi abaningi emakethe yobuchwepheshe bokucubungula i-calcium esindayo kanye nemishini, futhi izinkomba zobuchwepheshe zihola ekhaya noma emhlabeni jikelele. Kubatshalizimali, kunzima ukuqonda isimo sangempela. Kunconywa ukuthi abatshalizimali babhekisele ezixazululweni zobuchwepheshe zabakhiqizi bezobuchwepheshe abadumile emhlabeni wonke ukuze baqonde izinkomba zabo zobuchwepheshe lapho bebhekene nezixazululo zobuchwepheshe kanye nezinkomba zobuchwepheshe. Emkhakheni wokukhiqizwa kwemishini yemikhiqizo ye-calcium esindayo, izinkomba zobuchwepheshe ezithuthukisiwe zihlala zifana noma ziseduze. Ngokuphathelene nemishini yokucubungula i-calcium esindayo, emgqeni wokukhiqiza ofanayo, amandla afakiwe omenzi ngamunye wemishini angahluka ngo-30% noma ngaphezulu. Kuphela ngokukhetha amasu obuchwepheshe anengqondo nawesayensi lapho imiphumela emihle yokukhiqiza kanye nezinzuzo zomnotho ingatholakala khona.

Njengomkhiqizi onesipiliyoni seminyaka ecishe ibe ngu-30 ekukhiqizeni imishini ye-calcium powder, i-HCMilling (Guilin Hongcheng) inamakesi amakhasimende amaningi. Imishini yethu yokukhiqiza inqubo eyomile ye-calcium carbonate esindayo, njengei-calcium carbonate esindayo Umshini wokugaya iRaymond, i-calcium carbonate esindayo umshini wokugaya indandatho ocolekile kakhulufuthii-calcium carbonate esindayo umshini wokugaya oqondile oqondile omuhle kakhulu, inedumela elihle ekhaya nakwamanye amazwe. Uma unemibuzo mayelana nokuthi ungayikhetha kanjani intambo yokukhiqiza inqubo eyomile ye-calcium esindayo, sicela usithinte ukuze uthole imininingwane.
