Kaolin, cyane cyane kaolin nziza cyane ya calcium, nk'ikintu cy'ingenzi cyane kidakomoka ku byuma, cyagiye kigira uruhare runini mu nganda z'impapuro kubera imiterere yacyo myiza. Kaolin ya calcium ikoreshwa mu nganda z'impapuro ni ibikoresho bifite imyenge kandi bifite imiterere yera cyane, ahanini bikoreshwa mu gusimbuza dioxyde de titanium ihenze n'andi mabara meza. Nk'uruganda rukora ibikoresho byo gusya,kaolini irimo calciumihagaze neza cyaneikizingourusyo yakozwe na HCMilling (Guilin Hongcheng) yakoreshejwe cyane kandi izwi mu gukora kaolini ifite calcium. Ibi bikurikira ni intangiriro ku buryo bwo gukora kaolini ifite calcium:

Ibisabwa n'inganda zikora impapuro za kaolini ikozwe muri calcium bigaragazwa ahanini n'ibisabwa ku bunini bw'uduce, umweru, imbaraga zo guhisha, uburyo amavuta ashyirwa mu mubiri, ubunini bw'ubushyuhe, agaciro ka pH, agaciro k'ubusa n'ibindi bimenyetso bya kaolini ikozwe muri calcium. Kubera ko isoko rya kaolini isanzwe yogejwe ryagiye rigabanuka uko umwaka utashye bitewe n'ingaruka za karubone nyinshi ya calcium, kugurisha ku isoko byakomeje kwiyongera, byatumye abakora byinshi babikurikiza. Kuva mu myaka ya 1980, havumbuwe umubare munini wa kaolini y'amakara (bivugwa ko ububiko bw'amakara burenze toni miliyari 10). Kubera ubwiza bwayo buri hejuru n'imyanda mike yangiza, kaolini y'amakara yabaye ibikoresho fatizo byiza byo gukora kaolini y'amakara yo mu rwego rwo hejuru. Isoko ry'akalini ikozwe muri kaolini y'amakara ni rigari.

Uburyo bwo gukora kaolini irimo calcium bugizwe ahanini n'ibice bibiri: uburyo bwo gusya superfine n'uburyo bwo kwera calcium.

1. Uburyo bwo gusya ibintu bito cyane mu buryo bwo gukora kaolini ya calcium: uburyo bwo gusya ibintu bito cyane ni ingenzi mu kumenya ubwiza bwa kaolini. Gusya kaolini ito cyane mu buryo bw'amakara ni kaolini ikomeye (kuva kuri 5 ~ 20mm kugeza 40 ~ 80 μ m) Ultrafine (kuva kuri 40 kugeza 80 μ M kugeza kuri - 10 μ M cyangwa - 2 μ m).kaolini irimo calciumUruganda rwa Raymond n'uruganda rwa kaolini rukozwe muri calcined vertical roller roller rwakozwe na HCMilling (Guilin Hongcheng) ni ibikoresho byo gusya cyane, bishobora gukoreshwa mu gusya cyane uburyo bwo gukora kaolini ikozwe muri calcined, kandi bishobora gutunganya kaolini ifite mesh 80-600;Kaolin ya HLMX irimo calcium ihagaze neza cyaneikizingourusyo, uruganda rukora ring roller n'ibindi bikoresho byo gusya neza cyane birakwiriye mu gusya neza cyane mu buryo bwo gukora kaolini ifite calcium, ishobora gutunganya 3-45 μ M ifu ya kaolini nziza cyane ni uruganda rwiza rwa kaolini ifite calcium.

2. Uburyo bwo gukora kaolini ikoresheje calcium calcium: Ukurikije imiterere ya kaolini y’amakara, ni ukuvuga ko irimo ibintu bimwe na bimwe by’umwimerere, ku buryo umweru wayo w’amabuye y’agaciro ari 6 ~ 40% gusa, ibyo bikaba bitaragera ku rwego rw’ubuziranenge bw’inganda zikora impapuro za kaolini itwikiriwe, bityo inzira yo gukuramo kalisiyumu no kuyitunganya igomba kwemezwa. Dukurikije ibisabwa bitandukanye ku bwiza bwa kaolini, ishobora kandi kugabanywamo ibintu bibiri: kaolini ikoresheje calcium calcium carbonated mu bushyuhe buringaniye na kaolini ikoresha calcium calcium carbonated mu bushyuhe bwinshi.

Kugereranya inzira zo gukora kaolini irimo calcium: hakurikijwe niba inzira nziza cyane ari inzira y'amazi cyangwa yuma ndetse n'uruhererekane rw'inzira nziza cyane n'inzira yo gukaraba, inzira enye zishobora guhuzwa, ari zo

(1) inzira yo gutogosha ikoresheje amazi (wet superfine) ikurikirwa n'inzira yo gutogosha (2) inzira yo gutogosha ikoresheje amazi (3) inzira yo gutogosha ikoresheje amazi (4) inzira yo gutogosha ikoresheje amazi (wet superfine). Kubera ko abantu bafite imyumvire itandukanye ku bikoresho byiza cyane, inzira zikoreshwa mu bigo bitandukanye ziratandukanye:

(1) Uburyo bwo gukaranga neza cyane mu buryo butose ni burebure, ariko bushobora kwihutisha ibikoresho fatizo, kandi ubwiza bw'umusaruro bushobora guhaza ibyo inganda z'impapuro zikeneye;

(2) Uburyo bwo gukaranga no kongera kuvomera amazi muri rusange busaba ibikoresho byihariye byo kumisha n'ibikoresho byo gukwirakwiza. Ubu buryo ntibushobora kwifashishwa mu gutunganya ibikoresho fatizo, ariko bushobora gukora ibicuruzwa bikenewe n'inganda z'impapuro;

(3) Uburyo bwo gukaranga neza cyane hamwe no gukaranga mbere hanyuma uburyo bwo gukaranga neza cyane ntibushobora gukora kaolini yo mu nganda z'impapuro (kubera impamvu y'ibikoresho byiza cyane), bisaba ibikoresho fatizo bifite ubuziranenge bwo hejuru.

Muri rusange, inzira yo gukoresha superfine yumye mbere yo gukoresha calcination ifite akamaro gakomeye, kandi igishushanyo mbonera cy'inzira ni iki: amabuye y'agaciro → gusya → gusya → superfine yumye → calcination → umusaruro. Ibyiza by'iyi nzira ni ibi bikurikira: (1) inzira ni ngufi, kandi inzira yose isaba ibikoresho by'ingenzi bitatu kugeza kuri bine gusa. Niba HongchengUruganda rwa HLMX rukora ifu ya kaolin ultrafine hatoranijwe, hakenewe ibikoresho bitatu gusa, ari byo: icyuma gisya, uruganda rwa kaolin ultrafine powder, calciner, byoroshye gucunga muri rusange no gushyira ku murongo ukwiye; (2) Ikoreshwa ry'ingufu rirakwiye. Muri iki gikorwa, inzira nziza cyane y'ibikoresho ishyirwa imbere y'inzira ya calcination kugira ngo hirindwe ikibazo cyo gukoresha ingufu nyinshi bitewe no gusya no gutwika ibikoresho. Iyo inzira ya calcination y'ifu yemejwe, ishobora gufatwa nk'inzira yuzuye yo gukora yuma. Ku bijyanye n'ikoranabuhanga, ikoreshwa ry'ingufu rirakwiye kurushaho.

Gukoresha kaolini y'amakara mu gukora kaolini ifite calcium yo mu rwego rwo hejuru mu nganda z'impapuro nta gushidikanya ko ari uburyo bwiza bwo gukoresha gangue y'amakara mu buryo bushyize mu gaciro. Ni ngombwa kumenya ko inzira zikwiye zo gukora zigomba gutoranywa hakurikijwe umutungo w'aho uherereye n'imari shingiro. Niba ushaka kumenya byinshi ku buryo bwo gukora n'uburyo bwo guhitamo ibikoresho bya kaolini ifite calcium, turagusaba kuduhamagara kugira ngo umenye ibisobanuro birambuye.
