He kupu whakataki ki te kaolin
Ehara i te mea he kohuke uku noa iho te kaolin i te taiao, engari he kohuke kore-whakarewa tino nui hoki. Ka kiia hoki ko te dolomite nā te mea he mā. He mā, he pai, he ngawari te kaolin parakore, he pai te kirihou, te ātete ahi, te whakatārewatanga, te mimiti me ētahi atu āhuatanga ā-tinana. He nui ngā rauemi kaolin o te ao, ā, tata ki te 20.9 piriona tana te tapeke, e horapa whānuitia ana. He kounga teitei ngā rauemi kaolin i Haina, i te Hononga o Amerika, i Peretānia, i Brazil, i Īnia, i Bulgaria, i Ahitereiria, i Rūhia me ētahi atu whenua. Ko ngā rauemi kohuke kaolin o Haina kei roto i ngā mea tino pai o te ao, me te 267 ngā rohe whakaputa kohuke kua whakamātauhia me te 2.91 piriona tana o ngā rahui kua whakamātauhia.
Te whakamahinga o te kaolin
E toru ngā wāhanga o ngā konganuku kaolin puta noa i te ao, arā, te kaolin waro, te kaolin ngohengohe, me te kaolin onepū. He rerekē ngā whakaritenga kounga mō ngā momo tono, pērā i te kanapa nui, te matotoru iti, me te rahi o te matūriki pai mō ngā paninga pepa; he pai te kirihou, te āhua me te mā o te ahi mō te umanga uku; he pai te ātete o te ātete; he pai te whakatārewatanga o te umanga enamel. Ko ēnei katoa e whakatau ana i ngā whakaritenga kaolin o te hua, me te kanorau o ngā waitohu. Nō reira, ko ngā momo āhua o ngā rauemi te mea nui hei whakatau i te ahunga o ngā rauemi e wātea ana mō te whanaketanga ahumahi.
I te nuinga o te wā, he pai ake te kaolin waro o te whare (kaolin mārō) mō te whakawhanake hei kaolin kua whakapūkaratia, e whakamahia ana i roto i ngā momo mahi. Nā te mea he mā te kaolin kua whakapūkaratia, ka taea te whakamahi i roto i te hanga pepa, inā koa mō te hanga pepa paninga kounga teitei, engari kāore i te whakamahia ko ia anake nā te mea ko te oneone kaolin kua whakapūkaratia te nuinga e whakamahia ana hei whakanui ake i te mā, he iti ake te horopeta i te oneone kua horoia i roto i te hanga pepa. Ko te kaolin kore-wao (uku ngohengohe me te uku onepu), e whakamahia ana i roto i ngā paninga pepa me te umanga uku.
Te tukanga huri kaolin
Te tātaritanga wāhanga o ngā rauemi mata o te kaolin
| SiO2 | Al22O3 | H2O |
| 46.54% | 39.5% | 13.96% |
Te kaupapa whiriwhiri tauira mīhini hanga paura kaolin
| Whakatakotoranga (mata) | Paura pai 325mesh | Te tukatuka hōhonu o te paura tino pai (600 mata-2000 mata) |
| Kaupapa whiriwhiri taputapu | Mira huri poutū, mira huri raymond rānei | |
*Tuhipoka: tīpakohia te mīhini matua kia rite ki ngā whakaritenga putanga me te ātaahua
Te tātari i ngā tauira mira huri
1. Mira Raymond: He iti ngā utu haumitanga o te Mira Raymond, he nui te kaha, he iti te whakapaunga pūngao, he pumau ngā taputapu, he iti te haruru; he mira penapena pūngao tino whai hua mō te paura pai i raro i te 600mesh.
2. Mira poutū: he taputapu nui, he kaha teitei, ka taea te whakatutuki i te whakaputanga nui. He pumau ake te mira poutū. Ngā ngoikoretanga: he nui ngā utu haumi mō ngā taputapu.
Wāhanga I: Te kuru i ngā rauemi mata
Ka kuruhia te rauemi kaolin nui e te mīhini kuru kia tae ki te matotoru whāngai (15mm-50mm) ka taea te uru ki te mira huri.
Wāhanga II: Te Hurihuri
Ka tukuna ngā rauemi iti o te kaolin kuru ki te pūwero rokiroki mā te ararewa, kātahi ka tukuna ki te rūma huri o te mira kia ōrite, kia taurite hoki mā te whāngai hei huri.
Wāhanga III: Te Whakarōpūtanga
Ka mākahia ngā rauemi kua mira e te pūnaha māka, ā, ka mākahia te paura kāore i te tino tika e te kaiwhakarōpū ka whakahokia ki te mīhini matua kia hurihia anō.
Wāhanga V: Kohinga o ngā hua kua oti
Ka rere te paura e rite ana ki te matotoru o te paura mā roto i te paipa me te hau, ka tomo ki te kaikohi puehu hei wehe me te kohikohi. Ka tukuna te paura kua kohia ki te whare pupuri hua kua oti mā te taputapu kawe mā te putanga tuku, kātahi ka tākaihia e te waka tāke paura, e te tākai aunoa rānei.
Ngā tauira whakamahinga o te tukatuka paura kaolin
Ngā rauemi tukatuka: pyrophyllite, kaolin
Te pai: 200 mata D97
Putanga: 6-8t / h
Whirihoranga taputapu: 1 huinga o HC1700
He kōwhiringa tino whakaaro nui te mira huri a HCM hei mahi tahi me tētahi umanga pēnei me te pūnaha taurangi muri-hoko tino pai. He taputapu hou te mira huri kaolin a Hongcheng mō te whakapai ake i te mira tuku iho. Ko tōna putanga he 30% - 40% teitei ake i te mira Raymond tuku iho i ngā rā o mua, e tino whakapai ake ana i te pai o te whakaputa me te putanga o te mira waeine. He tino whakataetae mākete ngā hua kua oti te whakaputa, ā, he tino rongonui i roto i tā mātou kamupene.
