Mīra Huri Pēhanga Teitei HPGR
Tono
Ko te rōra huri pēhanga teitei kotahi-puku he mea hanga motuhake hei huri i ngā konganuku sima, te paru kohuke, ngā konganuku maitai me ētahi atu kia rite ki ngā kirikiri iti, hei kuru rawa i ngā kohuke whakarewa (ngā konganuku rino, ngā konganuku konupora, ngā konganuku parahi, ngā konganuku mata-konutea, ngā konganuku vanadium me ētahi atu) me te huri i ngā kohuke kore-whakarewa (ngā konganuku waro, te feldspar, te nepheline, te dolomite, te kōhatu kōhatu, te quartz, me ētahi atu) kia paura.
Hanganga me te Mātāpono Mahi
Kauwhata Mātāpono Mahi
Ko te rōra huri pēhanga teitei kotahi-puku e whakamahi ana i te mātāpono huri o te whakaputa rauemi. Ko tētahi he rōra tūmau, ko tētahi he rōra neke. Ka huri ngā rōra e rua i te taha whakarunga i te tere kotahi. Ka tomo ngā rauemi mai i te whakatuwheratanga whāngai o runga, ā, ka hurihia nā te whakaputanga e te pēhanga teitei i roto i te āputa o ngā rōra e rua, ka tukuna mai i raro.
Wāhanga taraiwa
Kotahi noa te puku motuka e hiahiatia ana, ka tukuna te mana mai i te rōra tūmau ki te rōra nekeneke mā te pūnaha taputapu, kia tino ōrite ai ngā rōra e rua, kāore he waku reti. Ka whakamahia katoatia te mahi mō te whakaputa rauemi, ā, he nui te tere whakamahinga pūngao, e penapena ana i te 45% o te hiko ki te whakaritea ki te rōra huri pēhanga teitei tikanga.
Pūnaha tono pēhanga
Mā te pūnaha pēhanga ā-pūnaha puna whakakotahi ka taea te karo i te rōra nekeneke. Ina uru mai he mea rino ke, ka hoki whakamuri te pūnaha pēhanga puna ka tauhohe i te wā tika, kia eke te tere mahi ki te 95%; i te mea ka taea te karo i te rōra huri pēhanga teitei tuku iho, me tuku te hinu waipēhi mā te paipa hei whakamama i te pēhanga. Ka whakaroahia te mahi, ka kino pea te mata o te rōra, ka hē rānei te pūnaha waipēhi.
Mata hurihuri
Ko te mata o te rōra he mea whakarewa ki te rauemi whakarewa ātete-mau o te koranu, ā, ka taea te pakeke te tae ki te HRC58-65; ka whakatikatika aunoa te pēhanga me te rauemi, e kore e tutuki noa te kaupapa o te huri, engari ka tiakina hoki te mata o te rōra; ka mahi tahi te rōra neke me te rōra tūmau me te kore e paheke te waku. Nō reira, he roa ake te ora o te mata rōra i tērā o te rōra huri pēhanga teitei tikanga.
Ngā Āhuatanga Hangarau Matua
■Te Tino Pai o te Mahi. Ki te whakatauritea ki ngā taputapu kuru tuku iho, ka piki ake te kaha tukatuka mā te 40 - 50%. Ka taea e te kaha tukatuka mō te PGM1040 te eke ki te 50 - 100 tana ia hāora, me te mana 90kw anake.
■He iti te whakapaunga pūngao. E ai ki te tikanga taraiwa hurihuri kotahi, kotahi noa te motuka e hiahiatia ana hei taraiwa. He iti rawa te whakapaunga pūngao. Ki te whakatauritea ki te HPGR taraiwa rua tuku iho, ka taea e ia te whakaiti i te whakapaunga pūngao mā te 20~30%.
■He Kounga Pai Ātete-Kakahu. Mēnā kotahi anake te motuka e taraiwa ana, he tino pai te mahi tukutahi o ngā rōra e rua. Mēnā he ātete-kakahu ngā mata whakarewa, he pai te kounga ātete-kakahu o ngā rōra, ā, he ngāwari te tiaki.
■Te Tere Whakahaere Teitei: ≥ 95%. Mā te hoahoa pūtaiao, ka taea te pēhanga i ngā taputapu mā te rōpū puna pēhanga teitei. Ka taea te whakarite aunoa i te pēhanga mahi kia rite ki te pēhanga rōpū puna. Kāore he wāhi hapa.
■He aunoatanga teitei, he ngāwari hoki te whakarerekētanga. Ki te kore he pūnaha waipēhi, he iti te tere o te hapa.
■Ko te mata o te takai he mea whakarewa ki te rauemi whakarewa ātete-kakahu koranu, he pakeke teitei, he ātete-kakahu pai hoki; ko te pēhanga ki te puna i ahu mai i te kaha tauhohenga o te rauemi, ā, he taurite tonu te pēhanga, e kore e tutuki noa te kaupapa o te kuru, engari e tiaki ana hoki i te mata takai; ko te takai neke me te takai tūmau he mea hono, he mea taraiwa e te pūnaha taputapu, ā, he tino ōrite te tere, kia kore ai e paheke te waku i waenga i te rauemi me te mata takai. Nō reira, he roa ake te ora ratonga i tērā o te HPGR puku rua.
■He hanganga kiato, he iti hoki te wāhi papa.
