Dombo reGaoling imineral inokosha zvikuru isiri yesimbi. Kaolin inogadzirwa nekupwanya, kukuya uye calcination ine hunhu hwakanaka, uye yave ichishandiswa zvakanyanya mumaindasitiri mazhinji, kunyanya muindasitiri yekuputira. Parizvino, mutengo wezvigadzirwa zvekaolin zvakajairwa calcined wakaderera, asi simba rayo rekufukidza harina kunaka, izvo zvinoderedza kushandiswa kwayo mumunda wekuputira kwepamusoro-soro. Izvi zvinoratidzwa kuti nekuwedzera kwehukuru hwezvikamu, simba rekufukidza rekaolin yakakanyiwa rinowedzera zvishoma nezvishoma, chikonzero chikuru ndechekuti kana zvikamu zvekaolin zvakapfava, simba rekufukidza rinokura.Kukuya kweKaolinmudziyo wekugadzira unoshandiswa kugadzirisa kaolin 300-1250 ultra fine kuti uvandudze simba rayo rekufukidza. Ndezvipi zvakanakira zvawo? Nhasi uno kubva kumugadziri wekaolin millGuilin Hongcheng kwamuri sumo yakadzama.

Mushure mekupwanya, kukuya uye kutsvaira zvakanyanya, 850℃ calcination, iyo inopa referensi inoshanda yekushandiswa uye kugadziriswa kwakadzika kwekaolin system yemarasha. Nekuda kwehuwandu hwayo hwakawanda hwesilicon nearuminiyamu, kaolin inopfava uye yakaoma kupfeka. Inofanirwa kunge yakapfava zvishoma (325 mesh sefa 5% ~ 10%), uye Raymond mill yakajairika haigone kuwana goho rakakura zvichibva pakupfava uku.
