Kaolin, makamaka kopitilira muyeso-chabwino calcined kaolin, monga zofunika kwambiri inorganic sanali zitsulo zakuthupi, wakhala mbali yofunika kwambiri mu makampani pepala ndi zake zabwino thupi katundu.Calcined kaolin ntchito pepala makampani ndi porous ndi mkulu whiteness structural zinchito zakuthupi, zomwe zimagwiritsa ntchito m'malo mtengo titaniyamu woipa ndi inki ena apamwamba amasankha.Monga wopanga zida zopera, ndicalcined kaolinultra-fine verticalwodzigudubuzamphero opangidwa ndi HCMilling(Guilin Hongcheng) wakhala ankagwiritsa ntchito ndipo anazindikira kupanga calcined kaolin.Zotsatirazi ndikuyambitsa njira yopangira calcined kaolin:

The zofunika za makampani pepala kwa calcined kaolin makamaka anasonyeza mu zofunika tinthu kukula, whiteness, kubisala mphamvu, mayamwidwe mafuta, mamasukidwe akayendedwe ndende, pH mtengo, kuvala mtengo ndi zizindikiro zina za calcined kaolin.Pazifukwa zomwe msika wa kaolin wotsuka wamba wakhala ukucheperachepera chaka ndi chaka chifukwa cha kukhudzidwa kwa heavy calcium carbonate, malonda amsika akhala akuchulukirachulukira, zomwe zapangitsa opanga ambiri kutsatira.Kuyambira zaka za m'ma 1980, chiwerengero chachikulu cha kaolin chakhala chikudziwika (akuti malo omwe akuyembekezeka kupitilira matani 10 biliyoni).Chifukwa cha khalidwe lake lapamwamba komanso zonyansa zochepa zowononga, kaolin ya malasha yakhala yabwino kwambiri popanga mapepala opangira mapepala a calcined kaolin.Chiyembekezo cha msika wa calcined kaolin wopangidwa kuchokera ku makala a kaolin ndi otakata.

The ndondomeko calcined kaolin makamaka zikuphatikizapo mbali ziwiri: kuphwanya njira superfine ndi calcining whitening ndondomeko.

1. Akupera superfine ndondomeko ya calcined kaolin kupanga njira: akupera superfine ndondomeko ndi ulalo wofunika kudziwa khalidwe la kaolin.Kuphwanyidwa kwa malasha angapo kaolin superfine ndi kolimba kaolin (kuchokera 5~20mm kuti 40~80 μ m) Ultrafine (kuchokera 40 mpaka 80 μ M kuti - 10 μ M kapena - 2 μ m).calcined kaolinRaymond mphero ndi calcined kaolin ofukula wodzigudubuza mphero opangidwa ndi HCMilling (Guilin Hongcheng) ndi coarse kuphwanya zida, amene angagwiritsidwe ntchito koyambirira coarse kuphwanya njira calcined kaolin kupanga, ndipo akhoza pokonza 80-600 mauna malasha mndandanda kaolin;HLMX mndandanda calcined kaolin ultra-fine verticalwodzigudubuzamphero, mphero yodzigudubuza ndi zida zina zopopera zabwino kwambiri ndizoyenera kuphwanya kopitilira muyeso mu njira yopanga calcined kaolin, yomwe imatha kukonza 3-45 μ M ufa wapamwamba kwambiri wa kaolin ndi mphero yabwino kwambiri ya calcined kaolin.

2. The calcination ndi whitening ndondomeko ya calcined kaolin kupanga njira: Poona diagenetic makhalidwe a malasha mndandanda kaolin, ndiko kuti, lili ndi zinthu organic, kotero kuti yaiwisi miyala whiteness ndi 6 ~ 40% okha, amene ali kutali. kukwaniritsa zofunikira zamakampani opanga mapepala a kaolin wokutidwa, kotero kuti calcination decarburization ndi whitening ndondomeko iyenera kutengedwa.Malinga ndi zofunika zosiyanasiyana za khalidwe la kaolin, zikhoza kugawidwa m'magulu awiri: sing'anga kutentha calcined kaolin ndi kutentha calcined kaolin.

Kuyerekeza njira ya calcined kaolin kupanga njira: malinga ngati njira superfine ndi yonyowa ndondomeko kapena youma ndondomeko ndi ndondomeko superfine ndondomeko calcination, njira zinayi kupanga akhoza pamodzi, ndicho.

(1) yonyowa superfine ndondomeko kenako calcination ndondomeko (2) youma superfine ndondomeko kutsatiridwa ndi calcination ndondomeko (3) calcination kutsatiridwa ndi chonyowa superfine ndondomeko (4) calcination kenako youma superfine ndondomeko.Chifukwa anthu amamvetsetsa mosiyanasiyana za zida zabwino kwambiri, njira zomwe zimagwiritsidwa ntchito m'mabizinesi osiyanasiyana ndizosiyana:

(1) The chonyowa superfine calcination ndondomeko ndi yaitali, koma ali amphamvu kusinthika kwa zipangizo, ndipo khalidwe mankhwala akhoza kukwaniritsa zofuna za makampani pepala;

(2) The calcination ndi rewetting superfine ndondomeko zambiri zimafuna zida zapadera zowumitsa ndi zida zobalalitsira.Njirayi imakhala ndi kusinthasintha kofooka kuzinthu zopangira, koma imatha kupanga zinthu zomwe zimafunidwa ndi makampani opanga mapepala;

(3) The youma superfine calcination ndondomeko ndi calcination woyamba ndiyeno youma superfine ndondomeko sangathe kutulutsa kaolin kwa makampani pepala (chifukwa cha zida superfine), amene amafuna mkulu khalidwe la zipangizo.

Ponseponse, njira yowuma kwambiri musanayambe kuwerengetsa imakhala yogwira ntchito kwambiri, ndipo chithunzi chamayendedwe ake ndi: ore yaiwisi → kuphwanya → kuphwanya → youma wapamwamba → calcination → mankhwala.Ubwino wa njirayi ndi: (1) ndondomekoyi ndi yaifupi, ndipo ndondomeko yonseyi imafuna zida zazikulu zitatu kapena zinayi zokha.Ngati HongchengHLMX calcined kaolin ultrafine powder mphero amasankhidwa, zida zitatu zokha zikufunika, zomwe ndi, crusher, calcined kaolin ultrafine powder mphero, calciner, yomwe ndi yabwino kwa kasamalidwe kambiri komanso kukonza koyenera;(2) Kugwiritsa ntchito mphamvu ndikoyenera.Pochita izi, njira yapamwamba kwambiri ya zipangizo imayikidwa patsogolo pa ndondomeko ya calcination kuti apewe vuto la kuwononga mphamvu zambiri chifukwa cha kuphwanya ndi kuyaka zipangizo.Ngati calcination ufa ndondomeko anatengera, izo zikhoza kuonedwa ngati zonse youma kupanga ndondomeko.Pankhani yaukadaulo, kugwiritsa ntchito mphamvu ndikoyenera.

Kugwiritsa ntchito malasha angapo kaolin kupanga ❖ kuyanika kalasi calcined kaolin kwa makampani pepala mosakayikira njira yabwino ntchito mwanzeru gangue malasha.Tiyenera kuzindikira kuti njira zoyenera zoyendetsera ntchito ziyenera kusankhidwa molingana ndi chuma cha m'deralo ndi ndalama.Ngati mukufuna kudziwa zambiri za njira zopangira ndi kusankha zida za calcined kaolin, chonde tiyimbireni zambiri.
