He Kupu Whakataki ki te Konumohe
Ka taea te tango ōhanga i te konganuku konumohe mai i te konganuku konumohe tūturu, ko te bauxite te mea nui rawa atu. E mōhiotia ana hoki te bauxite alumina ko te bauxite, ko te wāhanga matua ko te waikura alumina he alumina waikura kei roto ngā poke, he kohuke oneone; he mā, he hina rānei, ka kitea te tae parauri kōwhai, māwhero rānei nā te mea kei roto te rino. Ko te mātotoru he 3.9~4g/cm3, he pakeke 1-3, he mātotoru, he pakarukaru; kāore e wairewa i te wai, engari e wairewa ana i te waikawa whanariki me te wairewa konutai hauwai.
Te Whakamahinga o te Konumohe
He nui ngā rauemi o te bauxite, e hiahiatia ana mō ngā ahumahi maha; nō reira, he rauemi kore-whakarewa rongonui, ā, koia te take i tino manakohia ai, nā te mea he tino whai hua i roto i te ao ahumahi.
1. Ahumahi konumohe. He mea whakamahi te bauxite i roto i te tiaki whenua, te rererangi, te motuka, te hiko, te matū me ētahi atu ahumahi o ia rā.
2. Te whakarewanga. Ka tukatukahia te bauxite kua whakapūkaratia hei paura angiangi mō te whakarewanga i muri i te pokepokea ai, ā, e whakamahia ana i roto i ngā rāngai hōia, rererangi, whakawhitiwhiti kōrero, taputapu, mīhini me ngā taputapu hauora.
3. Mō ngā hua ātete ahi. Ka taea e te ātete ahi o te bauxite kua whakapūkarahia te eke ki te 1780 °C, he pumau matū, he pai hoki ngā āhuatanga ā-tinana.
4. Ngā muka ātete aluminosilicate. He maha ngā painga pēnei i te mama, te ātete ki te pāmahana teitei, te pumau pai o te wera, te kawe wera iti, te iti o te kaha wera me te ātete ki te wiri miihini me ētahi atu. Ka taea te whakamahi i roto i te rino me te maitai, te whakarewa kore-ferrous, te hikohiko, te hinu, te matū, te rererangi, te karihi, te tiaki whenua me ētahi atu ahumahi.
5. Ka taea te whakamahi i te rauemi mata o te konupūmā me te bauxite, me te tāpiri i te here e tika ana, mō te whakarewa i te raina rango whānui o te koko maitai rewa, ā, he tino pai ngā hua.
6. Ka taea te hanga i te sima bauxite, ngā rauemi whakakoi, me ngā momo matū mai i te konumohe bauxite i roto i te ahumahi uku me te ahumahi matū.

Te kaupapa whiriwhiri tauira mīhini hanga paura konumohe
| Whakatakotoranga | Te tukatuka hōhonu o te paura pai (200-400mesh) |
| Kaupapa whiriwhiri taputapu | Mira huri poutū me te mira huri Raymond |
Te tātari i ngā tauira mira huri
1. Mira huri pendulum a Raymond, raupapa HC: he iti ngā utu haumi, he nui te kaha, he iti te whakapaunga pūngao, he pumau ngā taputapu, he iti te haruru; koinei te taputapu tino pai mō te tukatuka paura konumohe. Engari he iti ake te nui o te tauine nui ki te mira huri poutū.
2. Mira poutū HLM: he taputapu nui, he kaha teitei, hei whakatutuki i te hiahia whakaputa nui. He teitei te āhua porowhita o te hua, he pai ake te kounga, engari he nui ake te utu haumi.
Wāhanga I: Te kuru i ngā rauemi mata
Ka kuruhia te konganuku konumohe 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 konumohe kuru ki te pūwero rokiroki mā te ararewa, kātahi ka tukuna ki te rūma huri o te mira kia ōrite, kia taurite hoki te rahinga e 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 tono o te tukatuka paura konumohe
Tauira me te maha o ēnei taputapu: 1 huinga o HC1300
Te tukatuka rauemi mata: Pauksite
Te pai: 325 mata D97
Te kaha: 8-10t / h
Whirihoranga taputapu: 1 huinga o HC1300
Mō te hanga paura me te whakatakotoranga ōrite, tata ki te 2 tana teitei ake te putanga o te HC1300 i tērā o te mīhini 5R tuku iho, ā, he iti te whakapaunga hiko. He aunoa katoa te pūnaha. Me mahi noa ngā kaimahi i roto i te rūma whakahaere matua. He māmā te whakahaere, ā, ka penapena i te utu mahi. Ki te iti te utu whakahaere, ka whakataetae ngā hua. Heoi anō, he kore utu te hoahoa, te aratohu tāutanga me te tono mō te kaupapa katoa, ā, e tino makona ana mātou.
