Zvinhu zvakagadzirwa nekaolin zvinopa imwe nzira inodhura pane zvinhu zvechinyakare zvakagadzirwa nesimbi, zvichipa kushanda kwakanaka pamutengo wakaderera.

Mamwe mashandisirwo emaindasitiri eupfu hwekaolin anosanganisira kushandiswa kwayo muzvinhu zvinodzivirira kusvibiswa kwemvura, jecha refoundry, uye zvinhu zvinokonzeresa kusvibiswa kwemvura. Muzvinhu zvinodzivirira kusvibiswa kwemvura, upfu hwekaolin hunoshandiswa kugadzira zvidhinha zvinodzivirira kusvibiswa kwemvura, zvinhu zvinokonzeresa kusvibiswa kwemvura, nezvimwe zvinhu zvinopisa zvakanyanya, uko kugadzikana kwayo pakupisa uye kusagadzikana kwemakemikari kwakakosha. Mujecha refoundry, upfu hwekaolin hunoshanda sechinobatanidza, huchivandudza simba uye kugona kuumbwa kwejecha, zvichiita kuti zvinhu zvinokonzeresa kusvibiswa kwemvura zvive pamusoro wakatsetseka uye saizi dzakarurama. Muzvinhu zvinokonzeresa kusvibiswa kwemvura, upfu hwekaolin hunoshandiswa sechishandiso chekutsigira, zvichipa nzvimbo yakakura yekuchinja kusvibiswa kwemvura.

Kupararira kwemafuta e kaolin pasi rose kunoita kuti pave nehuwandu hwakakwana hweupfu hwe kaolin hunoshandiswa mumaindasitiri. Matunhu makuru anogadzira kaolin anosanganisira North America, Europe, Asia, neAustralia, imwe neimwe ine huwandu hwakawanda hwe kaolin deposits dzemhando yepamusoro. Kufambira mberi mukugadzirwa kwetekinoroji, senge kukuya zvakanaka kwazvo, kugadzirisa pamusoro, uye kuchenesa, kwakawedzera huwandu hwezvigadzirwa zve kaolin powder uye kwakavandudza mashandiro azvo. Vagadziri vanotarisa pakugadzira mhando dzakasiyana dzeupfu hwe kaolin kuti dzisangane nezvinodiwa zveindasitiri, kubva pazvikamu zvakapfava zvakanyanya zvekuputira kwepamusoro kusvika kumhando dzakaoma dze ceramics nezvinhu zvekuvaka.

Kudzora mhando chinhu chakakosha pakugadzirwa kweupfu hwekaolin, kuve nechokwadi chekuti chigadzirwa chekupedzisira chinosangana nezvinodiwa zvemaindasitiri. Vagadziri vanoshandisa matanho akasimba ekudzora mhando kuti vatarise saizi yezvidimbu, kuchena, kuchena, nezvimwe zvinhu zvakakosha. Izvi zvinoita kuti hupfu hwekaolin hushande zvakanaka mumabhenji ese, zvichiita kuti hupfu hwekaolin huve chinhu chakavimbika chekushandiswa mumaindasitiri. Pamusoro pezvo, kutsvagisa kuri kuenderera mberi nekuedza kusimudzira kwakatarisana nekuvandudza matekinoroji ekugadzirisa uye kutsvaga mashandisirwo matsva eupfu hwekaolin, zvichiwedzera kushandiswa kwayo mukugadzira kwemazuva ano.
